This is a replacement mount / dock for a 36v 5.4Ah Canister battery for the new 2022 Sprinter kits and beyond. Controller and dock only. Controller is built into the base of the dock in a clever and waterproof case. A replacement Canister battery is available here. The Canister battery & dock are compatible with 36V Sprinter Hilltopper 9-pin motors from years 2020 to present.

For Hilltopper kits made prior to 2020 please see the universal replacement battery or contact support@hilltopperbikes.com with your model and estimated year for replacement battery options (for old 24v kits see our DIY battery module hack for one clever and thrifty option).
