OK, so this might be a retard question, but I have both a 6c and a 7c nimh battery. I think they are worn out and I need to get some replacements. Here's my question, should I go with a 2s lipo or stick to the 6s/7s? Will the 2s have as much power as the 7s? I'm assuming the lipo will give me longer run times. I have a mamba 5400kv motor if that helps at all. I'm just looking for somebody to give me a good break down. Thanks..

The typical 7 cell pack will give about 8 volts for appx 1-2 minutes, then equalize around 7-7.5 volts under a load for the remainder of the run. A decent lipo pack will give 7.4 volts under load consistently thru a run with less weight and more runtime per MAH.
