The V4 Power Unit is the battery and brains behind Campagnolo EPS 12-speed: a slim sealed unit that fits almost anywhere and rarely needs charging.

Highlights

  • Sealed unit, 16.6 mm diameter and 259 mm long
  • Fits inside the seatpost with a 27.2 mm or 31.6 mm adaptor
  • Alternative adaptor mounts it in the seat tube or down tube via bottle cage bolts
  • About 1700 km per full charge (about 400 km from 25%)
  • 10% more charge capacity than the previous unit

Cables

Supplied with cables of 1380 mm to the interface, 930 mm to the rear derailleur and 600 mm to the front derailleur.

Covered by Campagnolo's Limited Conventional Warranty against defects in materials and workmanship. For batteries and Power Units the warranty term is 2 years from the date of retail sale (3 years for other Campagnolo products), for the first retail purchaser with proof of purchase. Like all rechargeable batteries, charge capacity reduces gradually with use and age; normal wear, crash damage and incorrect use or charging are not covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with Campagnolo's Australian distributor.
