What to check before buying
Voltage first. Fitting a 3S pack to a 2S car can destroy the speed controller. Check the car’s manual or listing.
Physical size. Measure your battery tray. A pack that does not fit is no use, however good it is.
The connector. Buy the plug your car uses, or fit the matching connector to the pack. Never force mismatched plugs.
A proper charger. LiPos need a balance charger. Our best RC battery chargers guide compares them.
