Meet the Gladiator 72 Surge, our collaboration with Surge Stunts. Totally drop in, NO LID EXTENSIONS REQUIRED! Designed for Stunt Riders, but great for Sur-ron riders of all kinds! Unlock tons of new potential by upgrading to a 72V system and take your riding experience to the next level! 

The 72 Surge 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 top mounted discharge wires. The in-depth display allows the rider to be completely in tune with the battery. The display includes figures for Percentage, Voltage, Capacity (Amp Hours), battery temperature, Amps and Watts.

How does it stand in our lineup? 

The 72 Surge sets itself apart from the rest of our batteries by being the only true "stock fit" battery, meaning there are no lid extensions required. In addition, the 72 Surge features a thick 18awg steel case for additional protection and durability. 

The 72 Surge can provide 15KW of real-world continuous power, providing great flexibility for your power needs. If you are looking for a higher power 72V battery, check out our 72 Compact (22KW continuous) and 72 Max (30KW 

continuous). If you’re mostly looking for range, or do not intend to buy an aftermarket controller, take a look at our Gladiator 60 Series offerings!

This battery is a higher voltage and requires the use of an aftermarket controller to make it compatible, as well as a 72V charger. 

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.

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. 

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.
