DHS 72v 65ah Race Battery for Surron Ultra Bee – RS50 Cells – 61kw!

DHS 72V 65Ah Race Battery w RS50 cells producing 61kw peak!

An OEM-fit battery engineered for riders who demand maximum performance, instant torque, and high-output reliability. Developed with RS50 performance cells, this pack delivers class-leading performance without compromising fitment or safety.

Our take: Reliance RS50 tabless cells have overtaken Molicel P50b cells in overall total performance. RS50 cells in their 72v configuration are rated at 61kw peak and 850a at 100% charge. In our real-world testing, this battery can easily achieve 43kw+ at 600amps continuous without overheating.

This battery can be used with your OEM controller. The only thing we have not tested is the long-term viability of the controller and how it handles a battery this powerful. Technically, the controller should limit the power requested from the battery and work just fine. If you do not need the race spec battery, here is the normal 72v 65ah version.

No modification needed—This battery was designed as the perfect drop-in for someone looking for an OEM-size replacement with maximum performance.

The good news: no lead times! This battery ships from our SLC, Utah warehouse AND the charger is included!
