Batteries and controllers upgrades are all the rage because they allow to transform the Sur Ron into a rocket.

With a good controller and a proper battery, you can tune the power however you want. I opted for the ASI BAC 4000 and settled on 13kW.

At this power level and with a well programmed controller, the bike plays in the big league. It definitely compares to big petrol bikes in terms of power and acceleration, while keeping astonishingly manageable and nimble.

Still, it can loop you in no time if you're not careful so don't land that Angry Bee to your mom. It's not dangerous per-se, but as a 450cc, it requires a bit of experience to handle.

Regarding the battery, you can either use 60 or 72V. Good quality cells will deliver great power in both configurations. The latter being recommended for higher power as it'll be able to maintain lower current and won't heat as much, whereas the former will maintain compatibility with the stock controller.
