PTK5188ProTek RC LiFe 4PK/4PX/4PV Transmitter Battery Pack (6.6V/2100mAh)The ProTek R/C LiFe Car Transmitter Battery Pack is intended for use with the Futaba 4PK, 4PV and 4PX Transmitters. Lithium battery technology is evolving. With cell dimensions that fit anywhere a standard Li-Po 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 batt
