We are able to rebuild your Stromer batteries, but this is at your own request. We recommend contacting your local Stromer dealer, as these batteries are still being manufactured. If for whatever reason you cannot source a replacement, we are certainly willing to work with you if you want to replace your old cells with brand new ones if you don't want to purchase a whole pack. Please send in your charger if you would like us to rebuild your battery for any Stromer E-bike using our Battery Intake Form. We also have options to upgrade your battery capacity, depending on the model, for increased range. 

 Battery Intake Form

Send us your original Stromer Battery Pack made to fit the Stromer Sport and ST1s. We'll re-use your case so you know it'll fit perfectly. We can replace a worn-out battery and upgrade it for longer range.

Submitting payment online reserves your spot in our production line. You still need to send the battery and charger in using our Battery Intake Form so we can service your rebuild.
