Features

• No memory effect
• Longer storage life then NiMH Batteries
• Light weight and higher energy density than any rechargeable battery
• Installed PCB ( 5 Amp) will prevent the battery pack from over charge (> 8.4V), over discharge(< 5.5 V), Overdrain (> 5.0Amp) 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.
