I need to buy new packs, as this last weekend demonstrated that mine are nearing the end of the line (well over 100 cycles).
Has anyone got experience with the Turnigy Nano battery? Hobby King has them listed for not much more than the one I've been using and claims twice the cycle life as well as a higher recharge rate (5C!).
Supposedly there is an improved chemistry that lowers the resistance and makes for greater charge mobility.
The 2650 4S that I was using is $25 each and the equivalent Nano is $28. The Nano is 10 grams lighter, but is about 10mm longer which will take some internal whittling to fit in. If the Nano really doubles the cycles, it's a no-brainer.
