Is there some reason this radio sucks the life out of batteries so fast? I use good quality alkalines and the voltage drops off dramatically. I don't know if there is a low voltage alarm, but after one weekend, the voltage showing is about 5.3V on the screen and I start having my car going into failsafe because it is losing signal.

Put in a fresh set and all is good, but I'm getting tired of changing batteries every race weekend. I don't even do nitro any more with the long mains. My qualifiers are 6 minutes and mains are 12. I run two classes and maybe have one practice run for each on a race day. So that is maybe 75 to 80 minutes with the radio on and the batteries are shot????

It would be nice if you would check with the tech guys to see if the LiFe batteries would work. The voltage is significantly less than Lipo.
