KS Rage/LEV Circuit battery

The KS Rage/LEV Circuit battery powers KS Rage Circuit and KS LEV Circuit wireless dropper seatposts. Removable and rechargeable, it replaces disposable batteries and keeps your seatpost ready to use, without cables or connectors.

This 450 mAh lithium battery fits at the rear of the seatpost head, behind the saddle clamp, where a clip holds it securely in place. It simply slides out, allowing you to recharge it away from the bike.

With a typical battery life of around 8 weeks under normal use, it needs charging less often. Charging takes approximately 4 to 4.5 hours with the KS USB-C charger. A practical, more environmentally friendly alternative to disposable batteries, particularly suited to long rides or multi-day trips.
