How to derive battery output power
The voltage level of the battery determines the maximum electrical power which can be delivered continuously. Power P [W] is the product between voltage U [V] and current I [A]: [P = U cdot I tag{1}] The higher the current, the bigger the diameter of the high voltage wires and the higher the thermal losses.
