LiFe TX Battery Pack (9.9V/2100mAh) for Futaba, JR, Spektrum, KO

Sale price$69.99


This is intended for use with Futaba, JR, Spektrum and KO Propo Transmitters that use a 4x4 AA Battery Tray. With cell dimensions that fit anywhere a standard LiPo battery will and with rapidly increasing capacity, LiFe chemistry will soon set the standard that all others are judged by. With the ability to deliver 1000+ usable cycles, and a life span up to 4 times longer than LiPo batteries (when cycled under the same discharge conditions), these batteries offer the user an excellent balance of performance and value. LiFe batteries are more durable than LiPo and are able to handle a higher level of abuse when compared to LiPo without the risk of pre-mature failure. Unlike LiPo, LiFe cells can be stored in a fully charged state with little to no loss in stored power, and can be discharged deeper with less risk of damage to the cells. Most importantly, LiFe batteries are safer.

1) You will need a LiFe specific charger to charge the pack (NiMH, NiCD or Li-Poly only chargers WILL NOT WORK!)
2) You must not discharge the LiFe battery pack below 33% capacity during the break in period or below 2.5V per cell after break in.
3) It is not recommended that you charge this LiFe battery pack at amp rates higher than 1C.
4) Read the instructions carefully before operating this battery.
