    It is not an exact science. There are too many factors for a short journey to accurately measure. For instance, drawing current will heat the battery, as the battery heats the internal resistance drops and the battery can more easily deliver power, improving efficiency, so efficiency will...

    How do you know when it is fully balance charged?

    If it works like a standard lithium ion battery then max volts (on one cell) is 4.2V and as it discharges the voltage drops to dead at around 3.3V but it is not a straight-line so at 3.7v it's not far off dead. 375V at 75% sounds about right if 400v was max. You also get voltage sag (drop) as...
