How long does the battery last, and how do I charge the WHEELTOP EDS TX?
The WHEELTOP EDS TX battery provides 20,000+ shifts per charge (~60+ hours of typical riding), with a full charge taking around 2 hours using the proprietary magnetic charging cable. Simply attach the magnetic tip to the charging port on the derailleur. The rear derailleur battery is fixed with 4 screws and is not meant to be replaced by the rider; have a professional mechanic replace it.
