Are you ready to upgrade or replace your Sondors e-bike battery? Let EMP set you up with a higher power battery pack so you can have more fun on your ride! We can rebuild and repair your old battery pack and have it running better than new.

We can upgrade the bullet-style, water bottle mounted batteries up to 36V 14Ah. The triangle batteries have even more room for up to 65 cells, meaning we can potentially get those up to 36V 18Ah!
From the original Sondors fat e-bike, Thin, or Fold models, including 7 and X variants, we can make sure your battery has fresh, grade A cells for a longer, more powerful ride and longer life overall. We have options to fit any budget, with various lithium ion cylindrical or polymer pouch cells.

Just fill our our Battery Intake Form or give us a call at 1-888-456-9410 and we'll make sure you get what you need. We warranty our batteries for 12 months. We'll even recycle your old battery for you!

I have the original sondors and my battery won’t charge (I’m guessing it’s the BMS issues and the voltage is too low). Can you fix or even upgrade this? What’s the turnaround time?
Thanks!
