Spare Battery for 24 Volt Kits

Spare 24v Battery Pack

  • Small & Compact
  • Provides 12 - 16 miles of range
  • Replacement Battery for 24 Volt Kits
(6 reviews)

Replacement lithium-ion battery for all 24V electric bike kits (Economy, Sprinter, Commuter). Or an extra battery for very long rides. Range of 12-16+ miles. Built from certified Samsung cells.

If you purchased your Hilltopper kit before 2018 please call customer support at 206 682 7520 first to make sure this battery will fit your plugs (we changed all of our kits to plugs with an even higher waterproofy-ness rating in 2018 since we live in Seattle and it rains a lot).

Also, DIY tip: you can order a battery module for $60 less. Typically the module is what wears out first in an e-bike battery, so this hack is a great way for you to enjoy like new battery performance while also saving money. Ask for tips on how to do this, they may even offer to swap it out for free if you mail your battery in 😉

Woks great

This is the second purchase for me. They have really improved the battery size and the cables are easier to install. The sprinter battery is perfect for what I need.


Going strong!

Love this product. I live in New York city and every time I go out with my bike, everyone is amazed at the aesthetic and performance of my bike. I love racing the delivery guys downtown.
