How long does the battery last on a single charge, and how do I charge it?

The WHEELTOP EDS TX battery delivers approximately 24,000 shifts per charge (roughly 60+ hours of typical riding), and charging uses a proprietary magnetic charging cable that attaches directly to the derailleur port with a full charge taking around 2 hours. The OX2.0 battery is user-replaceable—simply remove 4 screws with a 2mm hex key to swap in a fresh battery pack.
