HYPERION G3 LiFePO4 Batteries for Radio Transmitters and Receivers
 
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!)
 2S 6.6V Receiver Pack
3S 9.9V Transmitter Pack 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.

Or you can purchase ready-made accessory cables such as shown below
HP-FG-CBL-2EHR is specifically made for radio transmitters, such as JR 9x, which use this 2-pin plug type. Connect this between your G3 transmitter pack, and the radio.
HP-FG-CBL-3STD is made for radio transmitters which use the 3-pin "servo" connectors, or can be used to power any standard receiver using a G3 6.6V receiver pack.
HP-FG-CBL-CHG is a Charge Cable, which allows the packs to be charged at high rates.
HP-FG-CON35-2P is two sets of 3.5mm connectors and insulators, allowing you to make any needed cable.
