Product Description
LiFePO4 Battery Balancing- Things to Remember
Here are some of the things you should keep in mind when balancing
a LiFePO4 battery:
Make sure the connections are tight. Loose connections can cause
sparking and fire.
Check the polarity of the cells, whether you are connecting them in
series or parallel.
Balancing is a long time so it is okay to leave the battery
unattended for intervals. However, you should monitor the battery
continuously when the cell voltage is near 3.5V.
The balancing system should be turned off at night since you cannot
regularly check on it.
Turn off the balancing system if there are unexpected occurrences
during the balancing process.
How to Maintain a LiFePO4 Battery and Keep It Balanced?
Keeping a LiFePO4 battery balanced is easy if you follow a proper
maintenance protocol. Maintaining a LiFePO4 battery is a very easy
task. Following the maintenance steps for LiFePO4 battery will
prolong the life of your battery and keep the cell balance intact
in the process.
Conclusion
LiFePO4 battery balancing can seem like a daunting task. However,
with the right battery and BMS, it is quite easy. Lithium batteries
have management systems that can handle your cell balancing
requirements.

Packing List
Wire connect
A single EK-C8S5A supports the use of 6 and 7 and 8 string battery packs. The wiring method is as follows:
EK-C8S5A supports cascading battery packs. Fox exmple, 3pcs of 8s cascade to 20s, see below drawing:
NOTE:As shown in the figure above,there can be multiple common ends of energy exchangeso that the efficiency of equilibrium will be higher;It is also possible to use only one common end of theenergy exchange atthejunction of two modules.The other free feet are suspended, and it is best todistribute the number of strings equally on each board.If you need the cascade diagram for more strings, Please contact our online service, Thanks.
