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.

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. Click here to order |

Best Budget LiFePO4 battery:
AmpereTime
|
If the SOK is out of stock, this is the next best budget battery. But it is lacking a basic safety feature: low temp charging protection.
What that means is that these must be mounted indoors or in an insulated box. If you are in the tropics, you are set! As long as the batteries never go below freezing, these work great. If you were to lower this batteries internal temperature to below freezing, and charged quickly, it will damage itself. So it is crucial to mount these in a warm location! Besides the low temp charging issue, it is a great battery! I have used them for months in a 48V pack. It is a very well made battery that should last a long time. I have many friends who use these packs without any issue as well. 12V Models 12V 100Ah Click Here to Purchase 12V 200Ah Click Here to Purchase 12V 300Ah Click Here to Purchase 12V 400Ah Click Here to Purchase 24V Models 24V 100Ah Click Here to Purchase 24V 200Ah Click Here to Purchase 48V Models 48V 100Ah Click Here To Purchase (AmpereTime's 48V battery is overpriced unlike their other models.

Battle Born 12 volt 100 amp hour
Lithium Iron Phosphate Battery Good battery, but expensive. If you want something that works great for years (or decades), buy this battery. I have not heard of a dissatisfied battle born battery buyer. It just works. I would go with the SOK/Ampere time battery above unless I needed a sealed battery, for marine application. The battleborn has the best case and terminals around, and can handle high moisture environments. It is also ideal for high vibration systems, such as RV's and vans.
These are safe to parallel connect in chains (to increase capacity of your system) with standard battery cables. If you plan to power large loads, you will need multiple batteries (for each 1000 watts required, use 1 battery. Example: 4500 watt load will require 5 batteries wired in parallel).
