Ploy for lipoly? Makes sense.

Wouldn't a 4cell have lower amp draw due to lower weight though? Which also would have an exponential effect on the decrease in losses?

Plus there are so many other areas that suffer from more weight and speed regardless of current. Tires, parts, heck... even the track barriers. lol
