Meet the Gladiator 72 Max - a 72V battery like no other, with near limitless potential. With speed, power, and range, the 72 Max has it all. This battery is a higher voltage and requires the use of an aftermarket controller to make it compatible, as well as a 72V charger.

Now comes in a steel enclosure, which is built in-house starting with a sheet of raw steel that is bent, welded, powder coated, and laser engraved by our highly trained fabrication team. Features an injection molded lid with relocated discharge wires. 

How does it stand in our lineup? 

The 72 Max is designed for riders who are looking for a top of line 72V battery to provide the best in performance. Crank up the power and leave everyone in the dust! With a rating of over 30kw of real-world continuous power and 43kw peak, (yes really!), the 72 Max allows you to push your bike to new limits with ease. The 72 Max requires you to swap your base plate (included) and is currently our tallest in the Gladiator line-up. If you’re looking for a 72V battery that fits with the stock base plate and has a lower profile, we recommend checking out the 72 Compact

This battery will require you to have a 72V compatible controller, as well as a 72V charger. The stock Sur-Ron controller and charger are not compatible with the Gladiator 72 Max. If you’re looking for a battery that is compatible with your stock Sur-Ron controller/charger, we recommend checking out the 60 Max, or one of our other 60V options

Order cancelation requests after 72 hours are subject to a 25% re-stocking fee. All battery sales outside of the lower 48 are final and cannot be refunded or returned. Battery servicing for Hawaii customers is outsourced to a local repair center. If you are having issues with a product please reach out to our support team.
