In this article, I will compare the best lithium batteries.
I will tell you which one to choose based on these criteria:
These are the best LifePo4 batteries
LiTime is known as Ampere Time. They have re-branded their battery line-up.
They have two versions, the normal and the mini. The mini uses pouch cells, while the normal version uses prismatic cells. Prismatic cells will last longer but are a bit bigger. I recommend using their normal version. This is the most value for money you will get. Here are a few remarkable features of this pricepoint:
There are two other models for this battery.
Use promo code ‘cleversolarpower’ at checkout and receive a 3% discount at the official LiTime store.
If you use the battery in freezing temperatures, I recommend getting the version with a built-in heater.
LithiumSolar reviews the Smart Battery with a low-temperature cutoff in the following video.
Choose the basic version if you want the best budget LiFePO4 battery (also called lfp battery). There is no Bluetooth connectivity and no low-temperature protection.
If your battery needs to be capable of absorbing vibrations or shocks like in a vehicle, then I recommend using the SOK Lithium battery.
SOK has an excellent reputation for delivering quality batteries at a reasonable price. They even offer a 7-year warranty if you buy from current-connected. They add 3 more years to that.
They have several versions:
I don’t have experience with them personally, but the reviews on amazon are all very positive. The customer service seems great. If you want to have a two pack of 12V 100Ah batteries, then this is your best choice. If you order this battery you can make a 24V 100Ah battery or a 12V 200Ah battery.
This battery doesn’t have low-temperature protection, so if you plan on using this battery, make sure your charge controller has a temperature sensor so it will disable the charging when the temperature goes below 5°C (41°F).
Lithiumsolar did a great review and teardown of this battery:
Is LiFePO4 better than lithium-ion?
Lithium-ion or Li-ion batteries are found in cell phones. These batteries are made for fast charging, but trade that with lifespan.
Did you notice that your phone’s battery has been reduced over its first few years?
If we change the batteries in our phones with LiFePO4 battery cells, we will get a longer lifetime, but the charging will take longer. That’s why a healthy trade-off with cycle life and charging speed has been made, and that’s why our phones use Li-ion batteries.
LiFePO4 batteries are in the same category as Li-ion batteries. Lithium iron phosphate is like part of the Li-ion family.
For solar systems, LiFePO4 is still preferred because it’s safer and doesn’t contain cobalt (source).
How good are LiFePO4 batteries?
Lithium iron Phosphate batteries have come a long way since their early development in 1996. These kinds of batteries are used in solar systems or electric vehicles.
Their development has made these the go-to battery chemistry for these applications.
Yes, if we use the cycle life of lithium cells we can calculate the following:
This article showed the best budget, durable, and reputable battery brands if you want to buy a lithium (LiFePO4) 12V 100Ah battery.
Since their smart battery is sold out, we have selected this as the best 12V LiFePO4 battery. This battery comes at a great price but without smart functions.
I’m an off-grid enthusiast. I created this website to give clear and straight-to-the-point advice about solar power. I’m also the author of the book ‘Off-grid solar power simplified‘. Read more about me on my about page, check out my channel, or send me a message.
I would like to know which battery should I buy for my off grid coiling systems in Africa?Champion 1, Li Time or which one?
It depends on your needs. I recommend using my off-grid solar calculator. Then you can see how many batteries you will need. If you need more than 5kW of storage, then I recommend using a server rack lithium battery.
