LiFEPO4 power for Rx and servos?

       Remove this ad - become a site supporter!
The Question:
Straight up: Is it or is it not okay to power servos rated for 6 volts with an unregulated 6.6V LiFEPO4? Here are the servos I'm using:

Channel 1
Port aileron
Hitec HS-5625MG
Rated for 4.8V and 6.0V

Channel 2
Port elevator
Hitec HS-5945MG
Rated for 4.8V and 6.0V

Starboard elevator
Hitec HS-5945MG
Rated for 4.8V and 6.0V

Channel 3
Hitec HS-625MG
Rated for 4.8V and 6.0V

Channel 4
Hitec HS-5945MG
Rated for 4.8V and 6.0V

Channel 6
Starboard aileron
Hitec HS-5625MG
Ratings for 4.8V and 6.0V

This is related to an ongoing issue I'm having with fried throttle servos (Throttle servos frying - cause unknown) but I want to ask this question in a separate thread.

Re: LiFEPO4 power for Rx and servos?

Hey John:

I have been using nothing but 6.6V A123's in all of my planes for the last 4 years or so with no issues whatsoever. Anything from .40 sized nitro planes to 50cc Gas.

I think that the issues you are having with your throttle servos are caused by some other situation you have going on.
