MAXIMUM POWER - 72V 42Ah EBMX SurRon Battery
Are you a thrill seeker that is after ultimate performance, extreme power density and up to a 15kW tune?! This massively powerful 72v battery will deliver all the thrills you could want and do it while still fitting in the stock SurRon battery slot as a plug and play solution. Note: this battery will require the use of a controller upgrade and will not run on the stock 60v controller. If you need a BAC4000/8000 controller to go with this new 72v battery, we may have a few left in stock (but don't tell anyone).

Trying to decide between 60v and 72v?
Both batteries are able to run the most powerful tune available (15kW and 600-800 phase amps). Both batteries are very powerful and capable. If the intended use for the bike is normal trail riding, we really like our 60v. 60v is plug-and-play in a stock bike, but also works very well with the 8.5kw BAC4000 tune. If the intended use for the bike is racing / track use, or steep hills for extended periods, wide open throttle, 200lb+ riders who ride hard, then the 72v battery is probably a better option. The 72v battery will run cooler in heavy load conditions (it draws less amps, and amps are what generate the heat). 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.
Nate runs a BAC4000 at 8.5kw with his 60v EBMX battery on 16/19" wheels.
Brian runs a BAC8000 at 12kw with his 72v EBMX battery on 18/21" wheels.
When riding together, at the same speed, we get almost identical range.
