Lithium Batteries for Solar Power Systems

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.

⭐Consistent Output

Most batteries on the market don't output as much current once they reach 50% of their battery life. This means that while you may have 50% of the battery remaining, the current is not very strong, so some of your accessories may stop working. In contrast, marine lithium batteries continue to output the same amount of current even when the battery life is below 50%. Not only that, but LiPo batteries can be completely depleted before they need to be recharged.

⭐Long Lasting

With ion lithium marine batteries, you need to pay more up front, but in the long run, these costs will save you a lot. Compared to lead-acid batteries, lithium marine batteries typically last 2 to 4 times longer (up to 10 times longer). Lead-acid batteries can usually be recharged 300 to 400 times. If you use it every day, this means it will last about a year. By comparison, our Diypow deep cycle lithium marine batteries are rated for 5000 cycles, which means they can be recharged 5000 times. If you use it every day, that's nearly 14 years of use. So while lithium marine batteries are initially more expensive, you're actually going to spend a lot less in the long run.

⭐1/3 Lighter Than Lead Acid Battery

For fishing boats, lightweight lithium batteries travel 1/4 mile more than boats using lead-acid batteries. In general, reducing the weight of the boat makes fishing easier. Diypow deep cycle lithium marine batteries are light weight, compact, fit in almost any boat, and won't weigh your boat down. You'll spend less money on gas and be able to drive better.

⭐6 Strong Protections

Our lithium batteries have a built-in BMS (Battery Management System) that provides protection against overcharge, overdischarge, low voltage, high voltage, short circuit and over temperature.

⭐Fast Charge

Our lithium battery provide 0.25C charge for standard and even 0.5C charge for customization. Lithium battery can be fully charged within 4 hours.

⭐Higher Discharge Rate

Our lithium batteries can provide a discharge rate of 1C, which is 5 times higher than lead-acid batteries. The higher discharge current can easily drive your device.

1. What is Lithium solar battery?

Lithium solar battery are simply lithium batteries used in solar power systems. More specifically, most lithium solar cells are deep cycle lithium iron phosphate (liFePO4) batteries, similar to the lead acid deep-cycle starter batteries commonly found in automobiles.

2. How do lithium solar batteries work with solar panels?

Solar batteries lithium are rechargeable batteries that store energy generated by solar panels. Here's how they work:

  • Solar panels convert sunlight into direct current (DC) electricity.
  • The DC electricity produced by the solar panels is sent to a charge controller, which regulates the charging process to prevent overcharging and damage to the battery.
  • The charge controller then directs the DC electricity to the lithium solar battery for storage.
  • The lithium solar battery stores the energy as chemical potential.
  • When electrical power is needed, the battery releases the stored energy in the form of direct current (DC) electricity.
  • The DC electricity from the battery is converted to alternating current (AC) electricity, if needed, by an inverter.
  • The AC electricity can then be used to power various devices and appliances. 

Overall, lithium solar batteries enable the storage and utilization of solar energy, allowing for a reliable power supply even when sunlight is not available, such as during the night or on cloudy days.

3. Is lithium battery good for solar?

Lithium batteries for solar are the best for storing energy in solar systems. They are more efficient, charge faster, require no maintenance and last longer. Their efficiency comes from the cells' low internal resistance, which allows them to be charged with minimal losses. Diypow has the best solar lithium battery.

4. How long do lithium solar batteries last?

On average, solar batteries lithium can last from 5 to 25 years. Lithium-ion cells are the most common type of solar cell, with a lifetime of up to 10 years. Factors that affect solar battery life are cell type, installation, depth of discharge, cycle life, environment and maintenance.

5. Do lithium batteries charge faster on solar?

Lithium batteries can be charged faster on solar energy if the solar panel system has sufficient energy output. The charging speed depends on factors such as the power of the solar panel, its efficiency and weather conditions. It is important to have a properly sized solar panel system to ensure optimum charging performance.

6. How do you maintain lithium solar batteries?

  • Keep it Clean: Regularly clean the battery and solar panels to remove dust and dirt.
  • Prevent Overcharging: Use a charge controller to avoid damaging the battery from overcharging.
  • Temperature Management: Protect the battery from extreme temperatures and store it in a cool, dry place.
  • Temperature Management: Protect the battery from extreme temp
  • Dispose of Responsibly: Follow local regulations for proper disposal of faulty or expired batteries and store them in a cool, dry place.
  • Follow Manufacturer's Instructions: Refer to the manufacturer's guidelines for specific maintenance recommendations.

7. How many panels does it take to charge a 200AH battery?

Charge the 200 AH battery to no more than 30 amps to avoid damage. Four 100-watt solar panels will charge one 200-amp-hour battery in five hours.

8. What are the 4 batteries for solar panels?

The four main types of solar batteries are lead-acid batteries, lithium-ion batteries, nickel-cadmium batteries and flow batteries. Of these three options, lithium-ion batteries will last the longest.

9. Should I charge my lithium battery after every use?

Unlike other types of batteries that need to be charged throughout storage, LiPo batteries do better at 40% -50% of the DoD (depth of discharge). Tip: After every 30 charges, allow your LiPo battery to fully discharge before recharging. This helps avoid a condition known as digital memory.

10. Why do lithium-ion batteries not last forever?

What causes lithium-ion aging? This lithium-ion battery has ion movement between the positive and negative electrodes. Theoretically, such a mechanism should always work, but cycling, elevated temperatures and aging reduce performance over time.

11. How long do lithium batteries last if not charged?

LiFePO4 batteries don't necessarily expire, but they do experience a small amount of energy drain when they are sitting still. In particular, when left in the right conditions, our LiFePO4 cells experience a 2-3% depletion per month.

12. How do I keep my lithium-ion battery healthy?

Charge or discharge the battery to approximately 50% capacity prior to storage. Charge the battery to approximately 50% capacity at least once every six months. Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).

13. Can you add lithium batteries to an existing solar system?

Yes, it is possible to retrofit an existing solar system with a battery pack. This is a great way to reduce the impact of power outages and make solar power available 24/7. solar panels are almost always compatible with energy storage systems

14. Do lithium batteries need a special solar charger?

Lithium batteries do not require a special solar charger. Solar chargers are suitable for all types of batteries, including lithium batteries. They can convert electrical energy into an electrical charge via solar energy, which is then stored in the lithium battery. This way you can use the solar charger to charge the lithium battery without the need for additional equipment.

15. How many solar panels does it take to charge a lithium battery?

You need approximately 310 watts of solar panels to charge a 12V 100Ah Li-ion battery with 100% depth of discharge during 5 peak solar hours using an MPPT charge controller.

16. Solid state battery vs lithium ion

Lithium-ion batteries consist of a cathode, anode, diaphragm and electrolyte. Lithium-ion batteries used in smartphones, power tools and electric vehicles use a liquid electrolyte solution. Solid-state batteries, on the other hand, use a solid electrolyte rather than a liquid.

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
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.

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.
