Installed PCB ( 5 Amp) will prevent the battery pack from over charge (> 8.4V ), over discharge( < 5.5 V), Overdrain (> 5.0A 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 18 G wire leads
