Amps

Abbreviation for "Ampere". A measurement for electric current. Sub-C battery packs are generally charged anywhere from 1-6 amps. Micro 2/3A battery packs are charged at 0.1 - 2.0 amps. When charging, more amps translates to more punch and acceleration, and less amps translates to more runtime. Racers prefer punch over runtime since their heats and mains are only a few minutes long. Bashers usually prefer more runtime.
