Light weight and higher energy density than any rechargeable battery
Installed PCB (2 Amp) will prevent the battery pack from over charge (> 8.4V), over discharge(< 5 V), Overdrain (> 2.0Amp) and Short Circuits. It helps protect battery chemistry integrity and prolongs battery life.
2 Amp polyswitch installed to limit max. discharging current at 2 A and to protect wrong polarity.
The battery module is wrap by PVC shrink and with 12 G wire leads
