How long does the battery last, and how do I charge the WHEELTOP EDS OX 2.0?

The OX 2.0 battery delivers approximately 24,000 shifts per charge—roughly 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 derailleur port for a full charge in about 2 hours, and the user-replaceable battery can be swapped by removing 4 screws with a 2mm hex key.
