Diypow Best Lithium Powerwall Battery

What are lithium powerwall batteries? Simply put, they store excess electricity generated by solar panels. When your solar panels are not producing energy, including at night and on cloudy days, the stored energy can power your home. They can also power your home when the grid fails.

Dipow's home energy storage battery features a sleek, patented design that fits nicely on the wall or on the floor. Multiple Powerwalls can be stacked together to increase stored energy and power more devices in your home or business. There is AC coupling which makes it easier to install into an existing solar panel system. This home energy battery is used for emergency backup. In addition, there are easy-to-use Bluetooth applications that allow you to monitor your home battery energy storage system in real-time and change the way they distribute power throughout the day.

Types of Home Energy Storage Batteries

Where and when is it in the best interest of your solar equipment to use lithium batteries? The following are some of the situations where our lithium iron phosphate batteries are particularly useful:


These batteries are inexpensive for short periods of time and can be recharged many times. However, they are also easily damaged and must be constantly maintained to avoid problems. It is very important to check and replenish the water level every few weeks or you could damage your battery. In addition, leaks can cause damage to the marine environment and pose many safety issues.


Sodium-sulfur batteries are high-temperature batteries. Sodium-sulfur batteries have a high energy density and can store more energy than conventional lead-acid or lithium-ion batteries. However, it requires higher temperatures, operating at 300-500 degrees. Sodium-sulfur batteries are still in the development and experimental stage, but there are still a number of technical and practical application challenges to overcome.


Comparing lithium batteries to other batteries is like comparing an iPhone to a flip phone. Both options will work, but one clearly has better reliability, functionality and design. Lithium batteries save a lot of money over time, they last longer, last up to 10 years, are much lighter, maintenance-free, and non-toxic to the environment. Especially lithium-ion batteries. They are the only lithium deep cycle batteries on the market today that use Bluetooth technology. This eliminates any guesswork or worry. With our lithium batteries (unlike other batteries), you know exactly how much power is left.

Tesla vs. Diypow Powerwall Batteries

Tesla Powerwall

Tesla has designed this AC battery system for residential and light commercial use. It uses lithium-ion batteries and runs quieter and cleaner than conventional gasoline backup generators. It has no exposed vents and no visible wires, making it a safer solution for homes with children or pets. 

The following are the technical details of the Powerwall:

  • Energy capacity: 13.5 kWh, can be combined with up to 10 Powerwalls
  • Power: 7 kW peak/ 5 kW continuous; seamless backup transition; pure sine wave output
  • Dimensions: 45.3 "L x 29.6 "W x 5.75" D
  • Mounting: Floor or wall mount
  • Warranty: 10 years


Since its launch in 2015, the Powerwall has become the best known in the solar cell sector. It features a sleek design that mounts nicely to the wall. Multiple Powerwalls can be stacked together to increase storage capacity and power more appliances throughout your home or business. In addition, the Powerwall is one of the cheapest solar cell options on the market.


Everyone is more concerned about the Tesla powerwall battery cost. The truth is that the price does seem a bit high and not everyone can afford the cost. Depending on when you order from Tesla, it may take a few months for your Powerwall to arrive. In addition, the Powerwall requires multiple electrical boxes and additional components to meet local electrical codes. These additional components take up space and limit your ability to incorporate them into a viable design solution while leaving you with fewer options for concealment.

Diypow Powerwall

Diypow is a system with an intelligent BMS and a large LCD screen. It can manage and monitor battery information including voltage, current and temperature, protecting the battery from overcharging, deep discharge, overload, overheating and short circuits, helping to extend the life of the battery. There are equipped with inverters that are fully compatible with the battery. Compared to the Telsa, the Diypow powerwall has many of the same features and an equivalent power profile.

The following are the technical details of the Diypow:

  • Rated energy: 10 kWh, up to 20.48 kWh when installed with a second Diypow wall-mounted battery
  • Power: Continuous power: up to 10.24 kW
  • Dimensions: Energy Storage System = 16.53 "L x 27.55" H x 10.19" W, Inverter = 18.5" L x 12.59" W x 5.31" D
  • Mounting: Wall Mounted & Stand Mounted
  • Warranty: 10 years


CAN/RS485/RS232 communication protocol lithium ion battery compatible with most inverters. Comes with its own Bluetooth BMS to monitor and manage the power used by the solar panel. Supports up to 32 batteries in parallel. Diypow batteries also typically operate at lower temperatures than their competitors, which increases the likelihood that the batteries will operate at maximum capacity for longer periods of time.


In contrast, Diypow may be inferior to Tesla in terms of brand awareness.

Powerwall Batteries Buying Guide

If you are a home user and want to save money on your electricity bill, if you are a commercial user and want to balance the peaks and valleys of electricity, reduce your electricity costs, find a reliable emergency backup power source, or if you are in a rural or remote area without a stable grid supply, you can choose Diypow's energy storage batteries to solve your energy problems.

Let's take a look at some of the problems you may encounter in purchasing energy storage batteries.

  1. Are the new Powerwalls LFP?
  2. Do any of the systems have a bumpless transfer from grid to battery in the case of an outage?
  3. Could I use a powerwall in an off-grid system?
  4. Is Diypow Powerwall worth it?
  5. How do I calculate how many solar installations I need?
  6. What’s a kWh?
  7. How big is a whole house battery backup?
  8. How long will a 5kWh battery last?
  9. How big should my battery be?
  10. If the power goes out, do I need to turn on the battery?
  11. If the battery is fully charged, how long will it last?
  12. Should the battery be outside or inside?
  13. What kind of battery do I need if I don't have a grid connection?
  14. How many batteries do I need for a 10kW solar system?

1. Are the new Powerwalls LFP?

Yes, Diypow batteries are all lithium iron phosphate(LFP) batteries made up of Grade A cells for greater safety, high energy density and a life span of up to 15 years.

2. Do any of the systems have a bumpless transfer from grid to battery in the case of an outage?

Yes, Diypow systems all have a seamless automatic transfer with no downtime.

Diypow Powerwall Batteries

3. Could I use a powerwall in an off-grid system?

Yep, you definitely could! If you are assembling a small house on wheels and have been looking for a solution to go with solar cells. Since Diypow lithium iron phosphate batteries are sold together with an inverter, this is a viable option.

4. Is Diypow Powerwall worth it?

Diypow powerwall total costs can be expensive upfront, but they are worth the cost due to the higher battery capacity and longer lifespan. If you have solar panels installed and want to be energy independent, the Powerwall will help you get there as the system stores any excess energy generated by the solar panels.

5. How do I calculate how many solar installations I need?

To calculate how much solar installation you need, you need to consider several factors such as your energy consumption, the efficiency of the solar panels, the available sunlight in your area.

Calculate required capacity: To calculate the required capacity of your solar installations, divide your annual energy consumption (in kWh) by the product of solar panel efficiency and available sunlight. The formula is as follows:
Required Capacity (kW) = Annual Energy Consumption (kWh) / (Solar Panel Efficiency x Available Sunlight)

6. What’s a kWh?

Kilowatt hours (kWh) are a measure in thousand-watt steps of how much energy an appliance uses in an hour. A 1,000 Watt microwave running for a maximum of one hour uses 1 kWh. So does a 100 Watt light bulb if it’s on for 10 hours.

This means that with 13.5 kWh of stored power, the Tesla Powerwall 2 could technically run your 1000 microwave for 13.5 hours. In reality, you may only use it for 30 minutes and use lights, the TV and other appliances as well.

But if you used less than 13.5 kWh of electricity daily, the Powerwall 2 could supply you with enough power for one day, if it were fully charged.

Keep in mind that although the Powerwall 2 can store enough energy to last 13.5 kWh, it outputs a maximum of 5 kW of energy at any one time. So you need to make sure you aren’t running more than 5 kW of appliances at once. If you were running 5 kW of appliances all at once and continuously, then the Powerwall would last less than three hours.

Diypow Powerwall Batteries

7. How big is a whole house battery backup?

The capacity of batteries is measured in kilowatt hours (kWh) and ranges from 1 kWh to over 10 kWh. Multiple batteries can be combined together to add more capacity, but 10 kWh household batteries are typical for most homes.

8. How long will a 5kWh battery last?

We have received a lot of questions asking about how long does a 5kWh battery last. Typically, a 5kWh solar battery can last approximately ten hours when you’re only running a few appliances, such as your TV, fridge, and even a few lights. However, it will drain quickly if you add the use of heavy-duty appliances, such as air conditioners. 

A 5kWh battery will have 5000 watts hours, or 5 kilowatt hours, of storage energy. A fully charged battery will be able to maintain the average fridge (200W) for approximately 1 day.

9. How big should my battery be?

The first thing to do is to check if batteries are a viable solution. This means that we look at the solar panel system you have installed. We want to make sure that you are producing enough electricity to supply your house and recharge the batteries at the same time. If you're not producing a lot of electricity, we don't want to give you a huge battery if you're not exporting a lot to the grid.

10. If the power goes out, do I need to turn on the battery?

Suppose it's daytime, it's hot, and the air conditioning is on throughout the house. The power is out. If the battery can't handle the load, it will shut itself off. You then have to turn off the air conditioning and turn the battery back on. But if you are not running a heavy load, the battery will automatically switch itself off the moment the power failure occurs. In the meantime, the battery remains charged from the solar panels in the background, even though it provides power to the house. (Remember that this only works if your house is on single-phase power.)

11. If the battery is fully charged, how long will it last?

It depends on what you are running on it. If you have a few lights on, watching TV and cooking, then the battery will last 12-13 hours. However, once you add a big consumer of electricity, such as an air conditioner or dishwasher, you will drain the battery much faster. It will then last for about two to three hours. If you have a single phase power and there is a power outage, you could potentially back up the whole house - as long as you don't run more than 5 kW of continuous power.

12. Should the battery be outside or inside?

It should go in a covered area, like a garage or a shed. We like to have it close to the electricity switchboard too.

Diypow Powerwall Batteries

It can be mounted outside, but because the sun shining on the battery will heat it up, we need to mount it on the east or south side. It can be mounted on the floor or on the wall.

13. What kind of battery do I need if I don't have a grid connection?

Whether you use solar power and are connected to the grid, or not connected to the grid at all, you will need a backup power source for night-time use or cloudy days.

If you're connected to the grid and it's cloudy for three days in a row, you won't have enough power to power your house or charge your batteries. So you need power from the grid.

In an off-grid system, you will need a generator for those cloudy days. But you also need off-grid lithium-iron phosphate batteries.

14. How many batteries do I need for a 10kW solar system?

In summary, a 10 kW solar system typically requires a battery pack with a capacity of 20-30 kWh, which may require 100-150 battery packs with a capacity of 200 amps.

15. How many kWh can a solar battery store?

The average household uses 8-10 kWh of electricity per day. The starting capacity of domestic batteries is around 2.5 -5 kWh, with small systems up to about 13-15 kWh for larger systems.

What Our Customer Say

Based on 29 reviews
NIce battery

More practical than a AGM lead battery for me. Much lighter (30 lbs). Can be discharged 100 % , compared to 50% on an Lead acid - so really equivalent to 200Amp-Hr (and then only 1/4 weight!).

Good battery for now

The vendor delivered the product sooner than expected and in great condition. Will use the battery to power a 12V 55Ibs trolling motor. So far, I am very happy with the product.

Double the power. Half the weight...!

EDIT: Tonight I cooked my dinner and used the oven for an hour and twenty minutes while I was watching TV with my mini PC on for streaming. This battery had more than enough juice to do all that with power left to spare.

I also have a 55 Quart 12V dual zone refrigerator and freezer connected and it runs 24 Hours a day.

This battery is incredibly powerful. It doubled my capacity and is half the weight. I also purchased the Diypow charger and am able to top it off in a very short time. I mainly purchased the setup for cooking while I'm on the road and I can use my 3-In-1 Galanz for about 40 minutes or so before I have to give it a little juice. My old setup used 4, 100 deep cycle batteries and didn't hold a candle to this Lifpo4 setup. I can definitely see myself getting a couple of these for our off-grid camp next spring. If you're in doubt, take the risk and go for it. You won't be disappointed. Almost forgot to mention that their customer service is outstanding. I did have several questions before I placed my order and they responded very quickly. I've been using this for about a month. Simply Great!

Only use these batteries if you know what your doing!

The Battery is rated at 50AH and on first discharge pulled 51AH down to 10.6 volts. Your getting the full rated capacity.
Its very light compared to the 45AH Lead Acid battery it is replacing.
No fumes or acid to deal with since this battery is inside the vehicle with people(trunk fender well to be exact)
LiFePo4 chemistry is a direct 12v Pb replacement.

Good price

Battery arrived early and after testing it and hooking it up, everything looks good. The seller emailed me after delivery to see if I had any concerns which was nice.

satisfactory for dry camping

Used with another same battery in a camper to get more days of service.

For my trolling motor on the beach

More power , light weight , charge lasts so much longer on my trolling Motor its amazing !!

Quality product and good customer service

I installed this in my 19ft RV connected to a 200w solar system and a 2000w invertor. So far works great, we're able to run the coffee maker, toaster and the 900w microwave in the morning. I may upgrade to 400w of solar to help speed up charging but so far it seems to be holding out really well. I've ordered a battery monitor to help manage the available power.

Excellent battery

I previously had a pouch cell 48v battery pack that lasted for about 1 year before it started holding less and less of a charge and started swelling. This battery has been excellent and seems to drain much slower that the pouch type battery packs. DIYPOW has excellent communication and shipping speed. The battery seems to be well made and came in well-cushioned packaging. I am using it on a 48v 1500w atv and it has no problem handling extended periods of max throttle. 5 star battery and company. Great battery and BMS for electric vehicles and I highly recommend it.

These batteries are exellent

These batteries are excellent so for. I purchased (4) 300Amp hour batteries.
They are 1/3 the weight of my old lead acid battues witch only lasts about 6 years.
I have them installed in series with a Schneider electric 4KW inverter:
They are also connected to a 15KW off-grid Generator (Generac).
If it has raining for days like it has been in Southern California, the 15KW off-grid Generator (Generac)
auto turns on to power up the potteries when they are lower than 50% capacity., So we are never with out power.
They batteries charge up many times quicker than my old lead acid batteries.
We have plenty off power with out 12 350 Watt solar panels.

very good battery, sooo happy convenient shipping, excellent product!

Works great for my diy solar system

Lithium battery for kayak trolling motor

Just because its an off brand, dont let it fool you. I use two of these to make 24v for my trolling motor for my kayak. Its an NK-180 motor. I run 14+ miles at 84% throttle! I had no issues, going on over a year now of frequent use. For trolling motors they work great. Im using a Noco two bank charger to charge them on the Lithium charger setting.

4 Pcs CATL 302AH Deep Cycle LiFePO4 Battery Cells
Karl Jensen
They look good and tested good.

The battery arrived intact and was one of the best matches of the 16 sets I encountered; voltage (0.003V Delta) and internal resistance (0.22 ohms - identical), most of the sides are flat with no swelling, and most importantly the soldered terminals have studs so you don't have to use tools to install the studs yourself. The bus bars are plated real copper, but I use 2/0 jumper diagonals to avoid straining the terminals. I will be doing a capacity test after the top is balanced and my expectations are very positive. nicole answered my questions and was very prompt in keeping in touch.

Update 4/19/23.
I did a quasi-capacity test and they far exceeded expectations. Conditions: 630 lbs compressed, top balanced. Running/starting at 56 volts (3.5 volts per section) and ending at 48 volts (3 volts per section). Loads ranged from 60 to 30 amps (normal house load) with two different meters showing results of 305 and 298 amp hours. Yes, there is more room at the top and bottom of the charge, which would allow for more capacity. Deltas are less than 0.008 at the flat of the curve during charging (60 amps) and discharging. less than 0.060v Delta at both ends. the balancer only starts working when each cell exceeds 3.4 volts. Float at 3.4 volts. Absorption/end charge 56.2 (3.512 volts per cell).

Great Quality

Put these in the RV. They have worked very well and we are happy to move away from our wet / lead acid batteries. Really liked the sturdy side post connectors for the wires hooking up to the batteries. Very sturdy.

I recommend 100%

I love this battery so far. I have it connected to a 36v minnkota trolling motor and I can have it on for 9-10 hours so far. Customer service is also A++

These are incredible batteries.

I have lived off grid solar for 33 years and these batteries (I have three) are great. With the help of a Diypow inverter I can now use a dishwasher, microwave, clothes washer and dryer and large tv all powered by the Sun. These batteries offer the greatest bang for the buck.

Arrived promptly

Arrived promptly & in excellent condition. Thanks!!!

Great LFP battery

I didn't rip it apart to check the BMS, but I've run it through a number of charge/discharge cycles now and it's been a champ. So far, so good. What is there to say? It acts like a 48V LFP battery pack.

One thing I will note, and this applies to all LiFePO4 (LFP) batteries, is that the BMS should always be viewed as a final fail-safe and not generally be relied on for over-volt and under-volt protection, because such protections may cause it to trip while current is flowing and that is never good for these FET power switches. It is always better to program your charge controllers with slightly lower voltage limits and always better to program other logic to shut equipment down when the battery is exhausted first, then "pull the plug" with a battery protect device, and make the breakers trip at slightly lower amperages, and not rely on the BMS in the battery itself pulling the plug for you. If you want your batteries to last, that is.

I will update the review after a few months of operation.

4 Pcs CATL 302AH Deep Cycle LiFePO4 Battery Cells
Very well matched set

The four cells are perfectly matched in voltage (<5mV variance). The vendor was very communicative during the international shipping crisis and got us the batteries as fast as was possible under the circumstances. Interesting that they fit perfectly in an Airstream Basecamp battery box with room for a BMS.

Very compact

Bought this to replace the same capacity AGM in my van conversion. Very compact and light weight compared to my 80lb AGM. Superior packaging and clearly written instructions. Arrived double boxed. Very impressed with the quality. Contacted the seller about charging and got an immediate response. Only time will tell if there is going to be an issue with the bms. Set my mppt solar controller to lithium and seems to be going the job charging to spec. Cant beat the price really, I paid almost this much for my AGM battery.

I'm loving the product

Although it took awhile for the battery to get to me I am very impressed with it. I put installed it into my 36 volt EZGO golf cart and it's terrific. Top speed hasn't changed much but acceleration has and I'm very surprised that I have played 36 holes and the volt meter has barely moved from from full without recharging. So far I would highly recommend it for a golf cart.

Trailer life

Excellent battery so far very happy survive the whole winter. Everything still working good first battery Ive had that actually last excellent battery perfect.

4 Pcs CATL 302AH Deep Cycle LiFePO4 Battery Cells
Don Owen
Good Cells

Ordered the 8 counts 310AH cells to set up a 24-volt system to a cargo trailer conversion. The shipping was very fast for me. Did a capacity test and got the full 310AH. After a couple of days of testing, I had a cell go bad. Howard help me troubleshoot the cell and we figure the cell did go bad. They then made things right without question and replace the cell at no cost to me. plan to order more in the future.

Does as advertised

I thought the BmS was faulty because it only charged to 52 volts. I decided to to test it anyway , so I charged it up to 52 volts let it sit overnight and tested it at its resting voltage of 49.8 volts this morning, I was so surprised to see the results, it stayed steady between 49 and 50 volt for hours as I was averaging around 6amps then it stayed between 48 and 49 volts for hours. I pulled 4KWH and it was still at 48.3 volts. Its a great battery , its well built has good dual positive and negative connections.

Perfect replacement for lead acid

Replaced two 58 Ah lead acid batteries with this 200Ah Diypow battery. I dont even plug trailer in anymore when Im home, its been 8 days now running 12 volt fridge and battery is still at 84%. Trailer has 1 -195 watt solar panel attached to roof and I have a 150 watt panel on a stand that I used to set up to help charge batteries, but I havent needed to use it with the new battery. So far I love this battery and May pick up a second one.
