Diypow Best Lithium OFF-Grid Batteries

The off-grid solar system packages with batteries use solar panels to convert solar energy into electrical energy when light is available, and supply power to the load through the solar charge/discharge controller, while charging the battery.

On cloudy days or when there is no light, the battery bank supplies power to the DC load through the solar charge/discharge controller.

At the same time, the battery also supplies power directly to the stand-alone inverter, which inverts the AC power to the AC load.

An off-grid battery bank is composed of solar panels, solar inverters and batteries. If the output power is 220V AC or 110V AC, a special off-grid inverter is required. The common battery capacity is 100Ah, 200Ah, 300Ah. can be configured as 12V system, 24V and 48V system according to different power demands, which is easy to use and widely applied.

Off-Grid Solar System Packages With 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:

⚡OFF-GRID SOLAR POWER SYSTEMS

Lithium batteries are a boon to country dwellers! If you've ever lived or traveled "off the grid," you know you can't live without batteries for your solar setup. In remote areas, you need batteries to store solar energy for future use. This is also true in places where there are massive power outages. Because lithium-ion batteries use energy efficiently, they keep the lights on longer. When you need 100% clean energy, lithium-ion solar cells are the perfect choice for off-grid systems. By forgoing grid power, you avoid using fossil fuels. When you add lithium batteries to your array, your solar energy will go further, making switching to an off-grid system even easier!

⚡BACKUP POWER FOR GRID-TIED SYSTEMS, OR HYBRID SYSTEMS

Lithium solar cells are perfect for providing backup power in the event of a power grid outage. For those who live in areas prone to natural disasters, storing solar power for emergencies is a must! This is also true for those in areas with unreliable power grids! This is also true for areas with unreliable power grids. Using a hybrid solar power system (grid-tied + solar + battery backup) gives you the best of all worlds. You can rely on solar power when it's available, grid power on dark days, and battery storage when all else fails. Not only can you reduce your electric bill by using solar power, but you're always covered in case of an emergency.

Diypow Lithium OFF-Grid Solar Batteries Buying Guide


There are many off-grid battery systems that use batteries as a backup plan for different areas, for example, home backup power, where an off-grid system can provide power to the home in the event of a power outage or disconnection, ensuring that the basic power needs of the home are met, such as lighting, refrigerators, communication devices, etc.

In most cases, all off-grid battery banks have a backup plan that consists of batteries whose role is to store current and then provide power when the grid-connected system does not respond.

In this complete buying guide, I will explain to you every single point about off-grid batteries. Which battery is best for you, which battery has the longest life cycle, and what the different advantages of using a battery in an off-grid system are.

This purchase covers the different features you need to know before you make a buying decision. Let us know more about this.

1. What is Off-grid system? 

As the name implies, off-grid systems are not connected to the utility grid and operate independently. Since these systems are not connected to the grid, battery storage is a must for these systems. 

Off-grid systems are designed to meet all the energy demands of their installation speed. For this purpose, huge battery storage capacities and off-grid inverters are used, which are quite expensive. As a result, off-grid systems are more expensive than grid-connected systems. These systems are best suited for locations away from the grid or located in remote areas such as military camps, communication towers, remote rural areas, mining areas, remote farms, street lighting or highway motels. Off-grid solar systems are also widely used by RVs and trailers to power their appliances. The benefit of using an off-grid solar system is that if you have enough backup batteries, you can enjoy an uninterrupted power supply even in the event of a utility outage.

Diypow OFF-Grid Batteries

2. What batteries are best for off-grid?

An off-grid system consists of solar panels a solar battery to store and supply power, and an inverter to control the input and output of generated power and optionally a backup generator.
LiFePO4 (LFP) batteries are the best batteries for off-grid solar. They have higher charging speed and low self-discharge rate, longer life cycle, safer and more environmentally friendly.

3. Is 12v or 24v better for off-grid solar battery?

If your energy needs are around 1,000 to 5,000 watts, choose a 24-volt system. If you want a smaller DIY system for your RV, van or small house, go with a 12-volt system.

4. How many batteries do I need for off-grid lithium battery?

If you want to keep the power on when the grid is off, you usually only need one solar cell. If you want to go completely off the grid, you need more storage capacity, a 10.24 kW Diypow powerwall, or 8-12 12V Diypow lithium batteries.

5. How long do off-grid batteries last?

On average, solar cells can last from 5 to 25 years. Lithium-ion cells are the most common type of solar cell, with a life span of up to 15 years. Factors that affect the life of a solar cell are the type of cell, installation, depth of discharge, cycle life, environment and maintenance.

6. What voltage are off-grid batteries?

Most people are beginning to explore off-grid solar systems with a system voltage of 12 volts. 12 volts is very common, which makes things easy because there are many options for batteries, inverters, chargers, and devices such as light bulbs that can use 12 volts of DC power.

7. How do grid batteries work?

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or power plant and then releases the energy at a later time in order to provide electricity or other grid services when needed.

8. How big should my off-grid battery be?

In a typical off-grid cabin application, you will have a 24 or 48-volt battery pack that ranges from 600 to 800 amp hours. In larger systems, a Diypow powerwall battery can reach 10.24 kWh.

9. What is the best off-grid battery for cold weather?

LiFePO4 or LFP batteries are suitable for almost all conditions (temperature range from -4 °F to 140 °F (-20 °C to 60 °C)). LiFePO4 batteries are an excellent alternative for continuous, reliable power for off-grid solar, RV and camper owners who live or travel in extreme cold climates.

10. What type of inverter is off-grid?

Off-grid Solar Inverter - Off-grid solar inverters are very popular and they come with backup power. Off-grid solar inverters work independently of the grid. Most household appliances such as fans, coolers, TVs, air conditioners, water pumps, etc.

11. Can batteries charge from the grid?

Some batteries can be charged with electricity from the grid during off-peak hours (usually at night), when electricity is cheaper than during the day. The energy stored in the solar cell system will be used whenever the home's energy use exceeds the level produced by the solar panels.

12. What is the best power source for off-grid home?

Solar. This is definitely a favorite for off-grid power systems and for a good reason. Solar panels use photovoltaic cells to harness the sun's energy and convert it to direct current, which an inverter can then convert to alternating current.

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.

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++

Arrived promptly

Arrived promptly & in excellent condition. Thanks!!!

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.

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
Ultrasound
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.

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.

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.

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.

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.

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.
