The Team Corally Sport Racing 50C lipo battery packs are particularly suitable for every hobby driver, basher and club racer. The Sport racing 50C battery packs have a discharge rate of 50C which is more than sufficient for any type of RC car with a brushed or brushless motor. The Sport racing 50C battery packs can be charged with up to 3C charging current (cycle life is shortened). The cells of Sport racing 50C battery packs are assembled under very strict selection criteria including voltage, internal resistance and voltage drift. All our Sport racing 50C cells have been submitted to an aging test of at least 21 days before being assembled. Because of these strict criteria we can guarantee the quality of all our Team Corally Sport racing 50C battery packs.
