Universal Replacement Battery

The Universal Hilltopper Replacement Battery - Available in December 2026.

Upgrade or replace your power source with ease. This 36V 8Ah battery serves as a universal replacement for all legacy 24V Hilltopper kits (Economy, Sprinter, Commuter, Twin Pack) as well as 36V Ranger kits.

Housed in a waterproof Tiger Shark case, this compact, slim battery features an integrated controller optimized for all 24V and 36V Hilltopper motors. Expect 16–20+ miles of range on a single charge.

Key Upgrades & Efficiency:

• 24V Legacy Kits (Sprinter, Economy): Upgrading to 36V increases your overall range by 50–60%.

• 36V Kits (Commuter, Ranger): Delivers a 10–15% increase in range over older packs.

• Variable Speed Throttle: Replacing a 24V setup upgrades you from a basic push-button to smooth, variable-speed control.

Important Compatibility Notes:

• Requires a 36V charger and matching cable set.

• Pre-2018 36V Kits: In 2018, we updated our connectors to higher-rated waterproof plugs (essential for our wet Seattle weather!). If your kit was purchased before 2018, you will need a new cable set to fit this battery.

• Upgrading from 24V? Be sure to select the battery + 36V charger + cable set bundle. Use promo code UpgradeTo36V at checkout to save $75 on your upgrade!
