I have a CBA III that indicates my Genuine Sanyo Eneloops stay above 1 volt all the way up to 8 amps and at 10 amps are right at 1 volt per cell. For those who might be interested, don't try to pass more than 4 amps through one of the regular battery/servo type connectors such as a Futaba "J". Ask me how I know and yes I have a scar on my thumb and forefinger as a reminder - that little plastic connector can get real hot.

I flew an AeroWorks Extra 50cc using 5 Hitec HS7985MG's and 1 HS7955TG for the rudder powered by two 5 cell packs handmade with Sanyo Eneloops for just about two years without a single problem. The receiver during that time was an AR7000 Spektrum using dual redundant switches etc. That plane is the one I'm standing beside in my avatar and I'm still flying it today although it now has dual redundant 2300maH A123's supplying the electrons. It does still have it's original Sanyo Eneloop AA 4 cell pack on the ignition.

No, I don't sport fly it, I beat the crap out of it doing things that most folks call me "crazy" for. Things like full throttle knife edge spins into inverted full throttle flat spins etc. Never had a brown out on the receiver nor any sort of battery related issue at all. I'm not saying that there aren't better ways to power your bird but the Eneloops provided me with many many hours of very reliable, very inexpensive fun when I first entered the big gasser scene.

P.S. This pic was taken when it had the Eneloops in it.
