These are fantastic batteries, at a fantastic price. But unfortunately, they are always out of stock and the customer support team can take a while to respond. 
 
FEATURES: 
  • Flexible Racking Options
  • LiFePo4 16-Cell Pack
  • Environmentally Friendly & Lead Free
  • Scalable. Add batteries as your budget allows.

I highly recommend sticking with the "Pro Model" EG4 if you can. It seems to have less issues.

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!

5kWh 48V 100A LiFePO4 Solar Battery

These are actually great batteries, but some people have complained to me that the customer support is awful. It is pretty much a clone of the SOK battery. Same exact cells and BMS. Even the inspection report looks the same. I would stick with SOK, but sometimes Jakiper has a good sale price.
  1. Size:442*460"177mm | Weight:45kgs
  2. 4000 Estimated Cycle Life to 80% capacity
  3. 100A Max Charge Current | 120A Max Discharge Current
  4. 19″ Rack Installation | or Rack Stack Installation with Side Handler
  5. Pre charge resistor and internal SOC shunt is included
  6. ​3X RS485, 1XCAN and 1X RS232 Communication Ports

Upgraded ​model! This one has stronger terminals (same as SOK) and updated firmware and an on/off switch. Really nice!

I have actually used a Jakiper battery in my main 48kWh system longer than any other server rack battery on the market. I have had zero issues with it, and I parallel it directly with other random packs I have lying around. 

Overall it is just as good as an EG4. The EG4 does have some fancy labels on the balance leads and a really cool looking plastic cover for the cell terminals, but both batteries use almost the same parts and both work well. The jakiper is taller than the EG4, so be sure to check the dimensions if that matters in your build.
