Function of PCB/PCM/BMS
· Main IC：（Different solution use different IC）
· Over charge protection： Connect charger between P+ and P- to charge battery to 4.2±0.05V(Based on customer requirement), the way to protect the battery is cut off the power.
· Over discharge protection: Connect application between P+ and P- to discharge battery to 2.5±0.1V(Based on customer requirement), the way to protect the battery is cut off the power.
· Short-circuit protection：when P+ and P- get short-circuit, PCB will cutoff the power in 5-50uS to protect the battery
· Over current protection: when B- and P- voltage to（0.15±0.02V）,PCB will cut off the power in 5-26ms to protect the battery.
