Lithium battery PCM and BMS


PCM or PCB ( protection circuit module or board ) is the "heart" of Lithium battery pack.  It will protect Lithium battery pack from overcharging, over-discharging and short-circuit, avoid Lithium battery pack from explosion, fire and damage.


For low voltage lithium battery packs (<20 cells), you shall choose PCM with equilibrium function to keep each cell in balance and good service life. For high voltage Lithium battery pack (>20 cells), you shall consider advanced BMS ( battery manage system) to monitor each cell's performance to ensure battery's safer operation.
