WebThe equation for the electric potential due to a point charge is \text {V}=\frac {\text {kQ}} {\text {r}} V = rkQ , where k is a constant equal to 9.0×10 9 N⋅m 2 /C 2. Key Terms electric potential: The potential energy per unit charge at a point in a static electric field; voltage. WebLiPo charger power is measured in Watt which is calculated by multiplying voltage (Volts) and current (Amps). If you are just charging one battery at a time, you don’t need much power. For example, to charge a 4S 1500mAh, the most you need is 1.5A x 16.8V = 25.2W (assuming you are charging at 1C).
