The Mighty Volt

If people want to run 24s LiPo with a 72v rated controller then simply charge the LiPo's to 4.0v. You will give yourself some leeway with the margin of error AND you will probably extend the life of your LiPo's. Personally I think trying to get 100v out of a 72v-rated controller is just asking for trouble in any case. Granted, its a PITA to have to switch to the 4115's but really, 88v is plenty. How fast do people want to go? And for how long? I agree with Jeremy on the reliability thing. 2000w in my X5305 in a 20" wheel at 72v {24s of LiFe} is plenty. Plenty to get up any hill, plenty to stay with traffic. Let us count our lucky stars that the Germans used to over-engineer their stuff too.
