Li-Ion Power Tool cells work great for RC!

Ask coolhand about LiMn, he runs them.

Lol, it seems we are playing "post-tag". :)

Some of the variables you mention are things I really don't want to worry about. That's one of the reasons why I like electric: plug it in and go. I don't want to have to worry if a cell becomes unbalanced, or if I am pulling too much current. All I have to worry about with NiMH cells is that I don't over-discharge them, and that's pretty easy to do. Like I said, when I build something, I over-do it so I don't have to worry about those things when I play. OK, so it's paranoia and laziness. :)

BTW: It looks like this topic is straying a bit off the power-tool-cell theme. Sorry for the unintended hijack! The conversation sort of evolved. :dft001:

Hopefully, coolhand will see this thread and chime in. In the meantime, I'll still be looking for the holy grail of lightweight, powerful, and small cells...
