Kalkhoff Battery Rebuild For Panasonic Mid Motors

Do you have a Kalkhoff e-bike with a Panasonic mid-mount motor that's not lasting as long as it once did? Send in your battery to us and we will replace the cells, upgrading your capacity and restoring it to better than new! Their original specifications were 259 Wh at 25.9V and 10 Ah. We can upgrade that to 15 Ah at the same voltage for 389 Wh and 50% more range! 

The Derby Cycle version below (shown for an Agattu Impulse 8 model) has a 10S 5P configuration with upgrade options up to 15Ah to give you almost 40% longer range than the original!

Just fill out our Battery Intake Form and send us your battery and charger. We will contact you with a quote and upgrade options. We recycle your old cells and re-use your case so you know it will fit back in your bike. We use brand new, grade A lithium ion cells and warranty all of our work for 12 months.
