The HobbyKing 1500mAh Transmitter pack fits snuggly into your FrSky Taranis X9D, most JR, Spektrum, or Futaba radios that take a square 8 x AA cell battery. With a capacity of 1500mAh, this LiFePo4 replacement for your old NiCD or NiMH will last four to five times longer.

Probably the best advantage of a LiFePo4 transmitter battery is that it will give an accurate voltage reading from start to finish which means you can say goodbye to the days when you thought your Transmitter was fully charged at home, only to find the voltage drop off rapidly when at the field.

LiFEPo4 packs also feature a much lower self-discharge rate than the NiCD and NiMH counterparts. With a nominal voltage of 9.9v, LiFePo4 cells closely match the NiMH cells most radios were designed for.
