Picked up some Tenergy LSD NiMh back in January, so far they work really good.

Don’t know how long they will go in our transmitters, never ran them down, I only occasionally charge them before big races just to be sure. But we are using DX3Rs which are real easy on batteries.

Haven’t touched the ones in the remotes, mice, keyboards, etc. They last a lot longer in the kids gaming stuff and a camera than anything I’ve tried before. Not including the Sanyo Eneloops, which by all accounts are excellent, but I couldn’t find them locally. (Edit: haven't tried any of the other LSDs mentioned)

For me they eliminate any need to consider a transmitter lipo, no over discharge or balancing to worry about. Highly recommended. (Edit: meaning LSD in general)
