Server Rack LiFePO4 Solar Batteries

High quality, high capacity solar batteries at a great price! These are taking over the market because they have everything. State of charge indicator, communication system, high quality BMS and a circuit breaker! These features improve the installation process and scalability substantially!

Previously, EG4 and SOK were selling the cheapest server rack batteries around. Now they are almost double the price of the competition! I started testing these batteries in my lab and they work surprisingly well. They pull the same capacity as the more expensive versions and even come with closed loop communication on some models. 
There are hundreds of these things available, but the ones I have tested are down below:

​Ecoworthy:
Version 3 of this battery is fantastic. It is on par with batteries that cost $300-$500 more. Actually, it is testing better than the other batteries. 105-106Ah capacity tests at a 1C rate. Closed loop communication. And now you can add an external screen. Company is now working on UL.

Vatrer:
Pulled best capacity out of all packs tested! Currently #1 on my list, but it does not have closed loop communication. But unlike the others, it has a screen and it is cheaper than the others! My favorite currently.

This company is new to the scene, but they have some pretty nice batteries. Every pack comes with:
  • Large Terminals (EG4 has small terminals and cannot fit 4/0 cables)
  • High Quality DC Rated Circuit Breaker
  • Internal Heaters! This usually costs a lot of money, but these packs have this feature included
  • High quality, expensive cells from EVE or CATL. These are best in the industry
  • No questions asked 10 Year Warranty that actually transfers to the next owner if you sell it
  • 10-20 Year Design Life​
  • The display is better than an SOK battery, but comparable to the pro EG4 model. Shows everything you need without having to clicking around.
I've actually been running these packs longer than EG4, and they work great. I have not had a single issue, and I prefer the trophy battery display and terminals. 

​This is also the only server rack with low temperature internal heaters. If you are in a cold climate and need some serious energy storage, these are for you.

For the price and features, I would say these are the best value all around. Great batteries! 

They have 3 sizes:
