SOK Lithium Server Rack Battery
Get this Server rack if you want a rugged internal design. The cells are packed in a metal rack inside.
The battery cells are serviceable. If you have a bad cell, you can replace it with another 100Ah cell. Other server racks have welded their cell together, which makes them not serviceable.
If you buy from currentconnected you can expect exceptional customer service.
EG4 or LiFePOWER4 Server Rack Battery
This server rack has outstanding specifications:
- It has low-temperature disconnect
- It has good customer support
- The price is very reasonable compared to other server rack batteries
The only downside is that it has 5 years warranty compared to other batteries like Jakiper that offer a 10-year warranty. However, I don’t think that is a big deal because the battery will likely not fail after those 5 years. If it fails, it will be on first use or after 10 years.
Lithium solar did a great review video about this battery.
Jakiper LiFePO4 Server Rack Battery
The Jakiper has been one of the first good server racks on the market. It features all the components you will need.
It has an LCD display so you can instantly see the battery statistics. With other batteries we have mentioned before, that is not possible.
However, I do not think it’s necessary to have this feature. If you use a shunt, you can see the battery’s state of charge.
EG4 LL V2 Server Rack Battery
This battery is an upgraded version of the standard EG4 48V battery. It has a display where you can adjust the settings and view the battery information without needing a computer.
This version has a display and two fire arrestors. If you are interested in the EG4 V1 battery (the one we recommend) but would like to add a display, then this version is for you.
It also holds a 10 Year warranty, just like the Jakiper server rack battery.
This is the best option if you want a low-temperature disconnect and an excellent battery.
