Overview
The ProTek R/C LiFe 4-Cell Car Transmitter Battery Pack is a premium 6.6V 2100mAh replacement battery designed to power popular pistol-grip RC car transmitters with the safe, stable chemistry of LiFePO4 (LiFe). With higher safety, more cycles, and a flatter discharge curve than NiMH or LiPo, LiFe is the smart long-term choice for transmitter power.
Built to drop-in fit for common Futaba, Sanwa, and KO transmitters that accept a 4-cell pack, this LiFe battery delivers all-day runtime and consistent voltage from start to finish.
