1 cell lipo pack = 4 cell NiMh?

[DrKnow65]

yes and no... higher C ratings tend to translate to lower internal resistance, but there are some 25c cells that hold their voltage better than 30c cells. No matter what you won't find a lipo cells that will stay at 4.2v even at 5c.

if weight is the issue, you can get a lower capacity with a higher C rating that should supply the amps you are looking for.

try to get a lipo that is 120% of the rating you need.

the problem is.... it is a 4 nimh cell 19t/10.5 pan car class and have a 2s lipo would be too high in voltage. is there a regulator to bring it down to 5v and handle the rigors of racing?
