Protek RC Futaba Spektrum Transmitter Life Battery (9.9V/2100mAh)

This is the ProTek R/C LiFe Transmitter Battery Pack and is intended for use with Futaba, JR, Spektrum and KO Propo Transmitters that use a 4x4 AA Battery Tray. Lithium battery technology is evolving. With cell dimensions that fit anywhere a standard Li-Poly battery will and 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 Li-Poly 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 Li-Poly and are able to handle a higher level of abuse when compared to Li-Poly without the risk of pre-mature failure. Unlike Li-Poly, 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 SAFE! There is no risk of combustion! LiFe cells will not catch fire or explode when over charged, or after a deep discharge.

• Safe chemistry will not explode or catch fire
• More mAh per gram compared to NiMH cells, meaning lighter models, and longer runtime
• Virtually no "self discharge", so the battery is always ready to go even weeks after charging.
• Superior voltage performance under load compared to NiMH cells, with consistent torque and speed.
• Fast charge time
