Are you a thrill seeker that is after ultimate performance, extreme power density and up to a 15kW tune?!

Trying to decide between 60v and 72v?

Both batteries are able to run the most powerful tune available (15kW and 600-800 phase amps). Although the 72v battery is not necessarily more powerful than the 60v battery, the 72v battery will run a little cooler in heavy load conditions (it draws less amps, and amps are what generate the heat). Both batteries are very powerful and capable. If the intended use for the bike is trail rider the 60v is probably the better option, if the intended use for the bike is racing / track use, then the 72v battery is probably a better option. Both batteries work with either BAC4000 or BAC8000. BAC8000 is better choice for more phase amps, which will give significantly more low down torque when accelerating.
