ProTek R/C 2100mAh 6.6V LiFe Transmitter Battery Pack – Reliable & safe power for Futaba transmitters

The ProTek R/C 2100 mAh 6.6 V LiFe transmitter battery is the ideal choice for operators who value reliability, safety, and longevity . This battery is compatible with the Futaba 3PV , Futaba 4PM , Futaba 4PV , Futaba 4PK , Futaba 4PLS , Futaba 4PX , Futaba 7PX , Futaba 10PX , Futaba 16SZ , and Futaba 18SZ transmitters.

LiFe technology offers over 1,000 charging cycles , a four-fold longer service life than LiPo batteries, no self-discharge , and maximum safety , as there is no risk of fire or explosion. LiFe batteries are more robust, more forgiving of deep discharge, and can be stored fully charged.

With a nominal voltage of 6.6 V, this battery offers a stable voltage curve that is significantly better than NiMH batteries— without the risks of LiPo . This makes it ideal for racers and ambitious hobbyists.
