Special Features 1.Libra-Meter is a very sophisticated electronic device that controlled by high performance microprocessor and precise resistors. it has three functions of "watt-meter", "battery checker"and "self-balancer". Those functions are essential for electric flyers to ensure safe battery condition and to measure the electric consumption of the power system. And also, the built-in self-balancer can equalize the individual voltages instantly. Libra-Meter can handle all types of Lithium batteries (LiPo, Lilo, LiFe) consisting of series-wired cells, but the battery pack has to have a balancing plug for checking voltage. -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. *Input: DC7.2-60.0V,0-100A *Output: DC7.2-60.0V,0-100A *Current loss: 20mA *Battery self-balance: 6 cells *Item size: 10.3×5.0×2.0cm *Item Weight: 5.7 oz Package Content: 1x Watt Meter 1x Balance Socket Board 2x Sets of Cable
