I started with Nmih in all my trucks. Then I got a loader and due to size and space constraints it came with a lipo. I'm sold on Lipo ever since. Everyone has given sound advice and cautions with these. The main reason I use is not just for the power. It's the reduced size that makes the difference. With all the electronics we add and have in our builds, the less space taken by the battery the better! I couldn't have my day cab the way it is without lipo.
Here's a size comparison for you. 2,000ma Nmih compared to a 2,200ma lipo.
