Meet the Gladiator 72 Colossus - a 72V battery like no other, with near limitless potential. With speed, power, and range, the 72 Colossus 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.

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 Colossus is designed for riders who are looking for a top of line 72V battery available to provide the best range of its class. If you want more speed and distance, you might have found your fit! You will be all set for long adventures with up to 4,320 Watt Hour of capacity. With the Standard Version rated for 22KW of real-world continuous power (34KW Peak), the 72 Colossus provides you with flexibility when it comes to tuning. Looking for even more power? The Pro Version of the battery is rated for 30KW (43KW Peak)! With an XT-60 top mounted charge port you can charge this battery as fast as 45 Amps with our Chi Charger. The 72 Colossus 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 without any lid risers we recommend checking out the 72 Pulsar

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 Colossus. If you’re looking for a battery that is compatible with your stock Sur-Ron controller/charger, we recommend checking out the 60 Odyssey. Compatible with 2024 Sur-Ron but requires QS8/QS10 version of the battery.

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.

Add On

QS8 Bike Harness:

This is a harness cable upgrade for your Sur-Ron, replacing the OEM bike harness to provide higher current capability. Comes with a Male QS8 connector with 7 AWG. This harness cable is not used with the Sur-Ron breaker, which can be removed from the bike, giving you more space for wire routing. The harness comes with an inline fuse pre-installed. Meant to be paired with the QS8 connector version of this battery.  QS10 versions of this harness with 6 AWG also available. 

How to correctly use the connectors: Plug in the first half of the connector for 3-5 seconds to allow for the filter capacitors to pre charge before making the full connection.
