What's the battery life on the WHEELTOP EDS, and how do I charge it?

The WHEELTOP EDS delivers approximately 24,000 shifts per charge (~60+ hours of typical riding). Charging uses a proprietary magnetic charging cable (not USB-C or micro-USB)—simply attach the magnetic tip to the port on the derailleur for a full charge in ~2 hours. The OX2.0 battery is user-replaceable: remove 4 screws with a 2mm hex key to swap a new battery pack when needed.
