Replacement Batteries

Replace or upgrade your Stromer battery. Extend the range of your bike, or keep a spare at the office that's always fully charged to take that scenic route home.

The BQ Range from Stromer have 78 lithium ion cells, specially developed for high performance with speed pedelec electric bikes.  

There is no memory effect with Stromer's batteries, meaning you can charge as much or as little as you want, as often as you need. Topping up won't damage your battery.

During winter, it can help extend range to store batteries in warmer environments and not let them get too cold.
