i personally made the switch in my 4wd buggy not to long ago and i hate to say it but i won't be looking back at nimh in that buggy. the power that i get from these trakpower lipo's is unreal. i run 2 heats easily on one battery. i don't have to re-peak cells or any of that time wasting nonsense that i have done for so many years with nimh. don't get me wrong, nimh has its place in many applications but for 1/10th scale lipo is the way to go.
