LiFe Racing Packs - How to?
Ok, thinking of going to LiFe batteries from Lipo's for safety reasons really, and trying to work out what I'd need to do to keep the same speed:
1. As the voltage is lower, would I need a lower turn motor, or just a gearing change, to get a similar speed? The C x Mah would be similar to my current cells, does that mean punch is similar, and therefore if I used a higher pinion to get the speed back I'd lose punch compared to Lipo? But if I go from say 5.5 to 4.5 I'd get more punch, is it all a case of finding a balance between the 2, and if so is it feasible to get that balance right? 2. What's LiFe efficiency like? Eg all things being equal would a 3500 pack give the same runtime as a 3500 lipo? Ignoring recovering the speed! Or is it lower efficiency, like nimh? 3. Anyone with any inside goss know if some life saddle packs have been sent for homoligation this year? I only know of one such pack even being around!
