Just wondering if lipo's are a better investment then NiMH, NiCd, or alkaline batteries. I was looking at some batteries and saw 7.4v 3600mAh lipo battery and was wondering if i connect them in parallel (i think that is what it is) if it is possible to achieve 7.4v 7400mAh? the higher the mAh the longer the runtime correct?

thanks

Yep, that is correct. Only you can determine if it is good investment though. Welcome to hobby talk. What kind of rc you have?
