TWO-METER is a very sophisticated electronic device that controlled by high performance microprocessor and precise resistors 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 consumptions of the power system. And also, the built-in self-balancer can equalize the individual voltages instantly. Connection board for Thunder Power and FlightPower batteries SOLD separately!!!!

TWO-METER can handle all types of Lithium batteries (Li-poly, LiIo, LiFe) consisting of series-wired cells, but the battery pack has to have a balancing plug for checking voltages.

Watt Meter: The Watt-meter circuit can measure the electric current up to 100A/60V. You can verify the electric consumptions on your power system.



Battery Checker: TWO-METER shows you the voltage and residual capacity of your Lithium battery pack with its individual voltage of each cell.



Integrated Self-Balancer: TWO-METER has an integrated self-balancing circuit (1S - 6S) 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 voltages will be equalized to the lowest cell voltage of the battery pack.
