About the LiFe Transmitter Battery
Safe, Long-Lasting Power
LiFePO4 chemistry delivers the stability and peace of mind every racer wants. Unlike LiPo batteries, LiFe cells will not catch fire or explode, even when over-charged or deeply discharged. Capable of more than 1,000 charge cycles and up to four times the lifespan of LiPo packs, this transmitter battery offers incredible durability with consistent performance every time you power on.
Better Than NiMH — Without LiPo Risks
With a nominal voltage of 6.6V, this 2-cell pack provides higher performance than standard NiMH batteries while remaining cooler, safer, and lighter. LiFe cells hold their charge far longer in storage and can be stored fully charged without degradation—ideal for transmitters that sit between race weekends.
Features:
-
Safe LiFe chemistry — no risk of fire or explosion
-
Long cycle life — 1,000+ usable charge cycles
-
Stable voltage under load for consistent transmitter performance
-
Virtually no self-discharge — always ready to use
-
Fast charge times and efficient energy delivery
-
Lightweight and compact — reduces transmitter fatigue
-
Compatible with a wide range of Futaba radios
Important Use & Safety Notes:
- Use only a LiFe-specific charger (NiMH, NiCd, or LiPo chargers are not compatible).
- During the first 20 cycles, avoid discharging below 33% capacity.
- After break-in, do not discharge below 2.5V per cell.
- Charge at 1C max for best lifespan.
- Always unplug or remove the battery when not in use.
