nOtE: this charger has a maximum output of 50 watts. you can determine the maximum
available current (a) by dividing 50 (W) by the battery pack voltage (V). W/V = a.
the maximum safe charge current that can be set is determined by the type of cells and
the manufacturers recommendation. this is often 1C (1 x capacity of cells) for LiPo and
niMh batteries.
