How does it stand in our lineup?
Are you having trouble deciding between 60V and 72V? Don't worry, we have an answer for that. The 66 Max is perfect for riders looking to begin their upgrade journey. Providing more range, power and speed, it is an all-in-one package for your Sur-Ron. It achieves this by utilizing the extra tolerance in your stock controller. For those who already have an upgraded controller, the 21700 Molicel cells give you 28kw of real world continuous power to work with. The 66 Max requires you to swap your stock base plate with a new one, which is included with your order. If you’re looking for a drop-in option with plenty of power, we recommend checking out the 66 Compact.
If you are mostly interested in range, checkout our 60V Sur-Ron Batteries, also compatible with your stock controller. Already upgraded to an aftermarket controller and have a need for even more speed? Our 72V Sur-Ron lineup might be of interest to you! The 66 Max requires a new charger, and will not be compatible with the stock charger. A standard charger is provided with this battery for free, or you can upgrade to a Variable charger.
