Features: Watt-meter program: the watt-meter circuit can measure the electric current up to 100A. you can verify the electric consumptions on your power system. Battery checker: Libra-meter can show you the voltage and residual capacity of your Lithium battery pack with its individual voltage of each cells. Integrated self-balancer: Libra-meter has an integrated self-balancing circuit which is self-operative without linking to charger. When you connect the battery pack to the individual port of the device the balancing job will be started instantly. In this case the individual cell voltage will be equalized to the lowest cell voltage of the battery pack.
Specification: Input power: Max 60V (both on watt-meter and battery checker) Max. current: 100A (watt-meter) Min operating voltage: 6.6V Current consumption: 20mA at battery checker program Dimension: 105 * 57 * 20 mm Weight: 87g
