RC car batteries
A hot streak on mini-car racing circuit should never be deterred by battery problems. Whether you’re a nitro running on 12 AA batteries or an electric running on 8, power and speed should never be compromised.
You may also want to run on RC car batteries with a 7.2 volt power, but whatever it is, it should always be fully charged before you go to race. The runtime on an electric car usually clocks in anywhere from 10 minutes to up to 30 minutes, depending on battery conditions. As for its fuel, a full tank of gas can run from 15-45 minutes depending on several conditions as well. Charging times usually vary, from as short as two hours and up to 10 hours. It is best to do the charging at least a day before intense use to stock up on battery life, unless you have a spare battery.
