A KEY improvement and a  brand NEW features for the Enerdrive B-Tech G2 LIthium Battery range is the  “Built-In Reset Button” making re-starting a flat battery a breeze. No longer do you need to apply a voltage to the battery terminals to wake up the battery. Press the button and within seconds, the battery will come back to life ready to accept a charge source to rejuvenate the battery.

Battery Management System

The other battery specifications remain relatively the same; battery weight, battery dimensions, max charge & discharge rates. The Prismatic Cell Design & Battery Management System (BMS) with Active Cell Balancing appears equal to the previous version. For those that don't know, the internal Battery Management System ensures safe and accurate operation of the battery. It monitors and optimises each Prismatic cell within the battery during normal operation. It will also protect the battery pack from over charge, over discharge, over temperature & short circuit.
