To bring up an old thread once again, I thought I would mention an alternative to lipo for the DX3r. Really, the only reasons for going lipo in a transmitter is flatter discharge curve and lower self-discharge. Well, how about using some LSD (low self-discharge) NiMHs? Doesn't really solve the flat discharge curve, but the high LSD of regular NiMHs can be a PITA if your radio is sitting on a shelf for a couple/few weeks. So, I've been doing a little reading and found this: http://www.stefanv.com/electronics/l...discharge.html. The cells tested here dropped only 0.04-0.07v after 7 weeks sitting on a shelf. That's a heck of a lot better than the Duracell NiMHs I'm using now. I'd probably opt for the cells that dropped the least, which is around 0.04v after 7 weeks, but even the worst ones would be better than nothing. Sanyo would most likely easiest to find, and I think I remember my LHS saying something about some LSD batteries they had. I might have to check them out.
