| You probably want to consider a Lipoly pack, they are very common and the cells are coming down in price to closer to comparable with nicd and Nimh for the voltage and capacity.
as far as the whole fire thing,
Not that I am aware of... they are not idiot proof (as far as safety is concerned like nimh cells are) but the only times that people gripe (check rcgroups, the lipoly penetration there seems to be very very very good) about them blowing up, burning things down, etc. is when charging (or should I say over charging) or after the pack has been heavily damaged in a crash. So what my buddies who are going to lipoly are doing is charging them in a fire resistant case (such as a metal ammo case lined with plastic with the lid shut) and putting it where it won't do damage if the pack goes up. That and they treat a damaged pack the same way, put store it in the metal case, and carefully dissect off the damaged cells and destroy them.
(the switching batteries shouldn't be a problem, as a primary power pack, you probably will want to have at least two around anyways)
