12V Lithium Solar Batteries
​for Beginners

The lithium batteries below are considered "Drop-in Lead Acid Replacement" because you can use them with standard 12/24/48 volt solar charge controllers/chargers/inverters and more. Simply hook them up to your system in the same way you would a typical lead acid battery.
​
They are also safer than lead acid (multiple protection features and non-combustible) and last 4-8X longer! Once you go lithium, you will never go back! The best lithium-ion battery chemistry for solar is LiFePO4 due to its safety and price.

My "Best Value" 12V LiFePO4 Battery for 2023

$669 for 12V 230Ah

I have tested a lot of batteries, and this one blows away the competition. If you want a budget battery that will not give you any problems, this is the way to go!
  • Low Temperature Protection. Every other battery at this price point does not have low temperature cut off. This one does!
  • 200A charge and discharge. This means you can run a 2,500W inverter, or charge with 2500W of solar, into a single battery!
  • EV Grade Battery Cells that are matched by capacity and internal resistance
  • Li Time 12V batteries have incredible surge capacity with their own dedicated BMS. Their trolling motor battery has a better surge than anything I have tested!
  • 2.94kWh for $669 w/ low temp protection is the lowest I have seen for a 12V battery with this build quality. This is cheaper than server rack batteries!
  • Li Time has sold tens of thousands of batteries with very low failure rate. Compare this to more expensive lifepo4 batteries that have BMS failures and other issues. The cell voltage differential on their cells is lower than batteries that cost 2X as much in my testing. 
  • This is their only large form factor 12V battery that has high charge and discharge rating, but also has low temp protection.
So overall, the best bang for your buck 12V battery I can find. Buy a few of these and save a ton of money.

The Ultimate Budget Battery

Li Time sells other models that are even cheaper than the battery above, but they do not have low temp charging protection. If you are in the tropics, or plan to store your batteries indoors, these batteries are a fantastic deal. I suggest most people stick with the battery above, but if you plan to never run your system in freezing temperatures, these are the best deal around and they have many sizes:

LiFePower4 (Budget Model)

$1,449 for 12V 400Ah
Click Here to Purchase
This battery has features that the other batteries on this page do not have, and for around the same cost per Ah:
  • Built in communication system! CAN BUS or RS485
  • Built in DC rated circuit breaker on LL model
  • State of Charge Indicator w/ Internal Shunt
  • Fire arrestor
  • Precharge resistor circuit (no need to use your own resistor)
  • Rated to 7000 cycles w/ DOD of 80%!
I think this is the best option on this page. Highest quality BMS with the best features. And a great warranty by a united states company. The only downside I can see is the reduced output current for the capacity. Most other smaller batteries can output more current compared to this pack. If you size your solar system properly, these batteries output is more than enough. So if you have a special circumstance that requires you to run large loads with a small battery, this one is not for you. But if you are using this for solar, it is perfect.

12V 300Ah for $999

Strange name, but this battery is one of my viewers favorites! It has low temperature protection unlike many of the other budget 12V batteries on amazon.com. I have never had a response to this company though, and have zero experience with their warranty process, but so far everyone loves them! 

Update: I recently ripped open another Weize battery and they changed the internal components. In my opinion, they were lower quality. So as always, you get what you pay for! I still am not hearing any complaints but you never know what youre getting with these cheaper batteries.

Bomb Proof 12V Battery, but Expensive! SOK Battery

This battery has the components of a $1000+ LiFePO4, at a fraction of the price. I have not found a better battery w/ warranty for the price of the SOK. Check out these stats:
  • Can be connected for use in 12V/24V/48V systems. Most budget batteries do not have this ability!
  • Can be serviced. If one of the cells fails in ten years, you can swap it out for a new one. If the bms fails, you can swap it out in minutes. 
  • 7 year warranty
  • Large durable terminals
  • Steel case
  • Low temperature charging protection

And it is well engineered! It is a tank of a battery, and can handle abuse for years. 
And the SOK has been cycle tested. Here is the life cycle curve where it is cycled 3500 times! Check it out:

Marine Environment SOK Battery

If you live near the ocean or plan to build a mobile system that needs to survive a rugged environment, check this pack out. 

Same cells and BMS as the classic SOK that everyone loves, but encased with a water resistant case. 

Over the years I have said that the original SOK might not be the best idea for high moisture environments because the case is made of steel. If you were to scratch the paint, you may have rust. No longer is this a problem.
