Batteries and Mounts

Every electronic shift system is powered by some sort of battery, and different bikes have different types of battery mounts. From internal batteries, which are often housed inside the seatpost or seat tube, to external style batteries that can be mounted under a chainstay, at the water bottle mounts or other out-of-the-way places on your frame, we have everything you need to keep your system charged up and running smoothly.

Whether you need to replace a worn-out battery, or you want a spare for your kit, we carry batteries from major brands including Shimano and SRAM. Our collection also includes battery chargers that are compatible with the most current electronic drivetrains as well as older model systems. If you have any questions about compatibility or which particular battery or mount will work best with your electronic drivetrain and frame, call one of our JensonUSA Gear Advisors at 888-880-3811 to help you get it sorted.
