Installed PCB (4 Amp) will prevent the battery pack from over charge (> 12.6V ), over discharge( < 7.5 V), Overdrain (> 4.0A mp) and Short Circuits. It helps protect battery chemistry integrity and prolongs battery life.
4.2 Amp polyswitch installed to limit max. discharging current at 4.2 A and to protect wrong polarity.
The battery module is wrap by PVC shrink and with 22 G wire leads
