These cells need to be connected together with the appropriate bus bars. Our default quantity is 1 busbar per cell, so a 4 cell pack would get 4 busbars. Hardware for attaching busbars to the cells is included.
Typically, 4 or more of these cells will be wired in series or parallel-series with a Battery Management System (BMS) to create a 12 volt battery, 8 cells for a 24v battery, or 16 cells for a 48v battery, with a suitable BMS. They may be paralleled at a cell level to increase your overall capacity (Ah).
It is very important to use a BMS to manage these cells. Here’s Why
LiFePO4 chemistry is easily damaged by over charging, over discharging, over/under temperature, and especially low temperature charging. Use a BMS that monitors each series-connected cell (or group of parallel connected cells) and has a low-temperature cutoff.
Our recommended BMS units:
- 500A REC-Q BMS for 8S or 16S Packs
- 500A REC A BMS for 4S Packs
- 150A/100A/100A JBD BMS for 4S, 8S, or 16S Packs
