Balancing is the process of equalizing the voltage and state of charge (SOC) of each cell in a battery pack. This prevents overcharging or undercharging of individual cells, which can cause damage, reduce capacity, and shorten lifespan. Balancing can be done either during charging (top balancing) or during discharging (bottom balancing).
Yes, generally a LiFePO4 balancer should be used for top balancing as well as bottom balancing technique. The balancer refers to an electronic circuit or simply a module responsible for detecting individual cell voltages in the battery pack and, in the process, actively compensating for them when required.
Generally if your cells are new and their voltages are very close to each other, the balancing function of BMS can make them balance slowly during charging. So there is no need to do top balancing, you can just assemble them into a battery pack.
In LiFePO4 batteries, as soon as the cell with the lowest voltage hits the discharge voltage cut off designated by the BMS or PCM, it will shut down the entire battery. If the cells were unbalanced during discharge, this may mean that some cells have unused energy and that the battery isn't truly “empty”.
