WHEELTOP Wireless Derailleur Battery Life: Specs, Charging and Tips

WHEELTOP EDS battery specs for each model, how to charge and check battery level in the app, and how to get the most from each charge.

Quick answer: WHEELTOP EDS rear derailleurs (TX, GeX and OX 2.0) use a built-in 800mAh 7.4V (5.92Wh) lithium battery, rated by WHEELTOP at 20,000+ shifts per charge. The TX front derailleur uses a 500mAh 7.4V (3.7Wh) battery. All charge through a magnetic connector, and the WHEELTOP app shows each part's battery level.

WHEELTOP EDS Battery Specs by Model

  • TX rear derailleur: 800mAh, 7.4V, 5.92Wh
  • GeX rear derailleur: 800mAh, 7.4V, 5.92Wh
  • OX 2.0 rear derailleur: 800mAh, 7.4V, 5.92Wh

How Long Does a Charge Last?

WHEELTOP rates the rear derailleur at 20,000+ shifts per charge. Real-world range depends on how often you shift, terrain and temperature, so check the battery level in the app before longer rides. Cold weather can reduce battery performance; see cold-weather tips.

Checking Battery Level in the App

After pairing, the WHEELTOP app home screen shows the live battery level of every connected component: derailleurs and shifters.

How to Charge

Snap the magnetic charging cable onto the derailleur's charging contacts. Make sure the contacts are clean and dry first. Attaching the charger also wakes new parts, which ship switched off.

Getting the Most From Each Charge

  • Charge before long rides and events
  • Keep contacts clean after wet or muddy rides
  • Keep firmware up to date (firmware update guide)
  • Store the bike indoors in cold weather
