8 battery metrics that really matter to performance

Battery power refers to the rate at which an electrical current can be moved through a battery, and it''s measured in watts, or more often C-rate. The higher the power, the faster a battery can deliver its stored energy (or store incoming energy). C-rates are commonly used to describe battery power. For example, a 1C discharge rate describes ...
