LiFePO4 9.9V 2100mAh TRANSMITTER PACK, for any transmitter using Standard 2x2x2 BLOCK 8-Cell (9.6V) Nimh packs. Includes Safety PCM circuits to allow charging inside Transmitter, using standard wall NiMH charger.

These are LiFePO4 Transmitter Power Packs, with high-rate 3.5mm gold charge/discharge plugs, and Hyperion-style Balance Tap.
See DATASHEET for full specifications and usage guidelines.

Almost all transmitter and receiver power packs today are made using NiMH cells. Many users have noted the much higher capacity or lighter weight of Lipo cells, but LiPo have voltage "too high" (3.7V/cell) to work reliably with most transmitters, receivers, and servos.

But unlike LiPo, LiFePO4 cells (3.3V/cell) can be an excellent replacement for NiMH on voltage basis.

And compared to high-capacity NiMH packs, the Hyperion G3 LifePO4 Radio batteries have these other advantages:

More capacity per gram, meaning lighter models in flight, and longer transmitter duration
Almost no "self discharge", so your radio is always ready to go even weeks after charging.
Superior voltage performance under load, so your servos perform with more consistent torque and speed.
Faster charge time (as fast as 15 minutes!)

In addition, the LiFe chemistry is not subject to "thermal runaway" fires, which can occur when LiPo are overcharged, making LiFe a much safer alternative.

Hyperion - as well as other quality digital servos makers - will be introducing "High Voltage" servo types which can handle both LiFePO4 and LiPo voltages. However, unlike LiPo, LiFePO4 can be stored in a fully charged state, and discharged deeper, without damage to the cells. So they are more "rugged" than LiPo, safer, more convenient and a better choice overall.

In the LiFe pack photos, you can see a Hyperion-style balance connector, and also a red connector with 3.5mm gold plugs, and a "spare" connector set. The red connector allows these packs to be charged at high rates. The "spare" can be attached to your existing Radio plug, or used to make a charge cable.
