While Campagnolo Electronic Power Shift boasts the best battery life in the electronic shifting market, after a thousand miles or more, you're going to need to charge the system. Campagnolo makes this process relatively painless with its new EPS Charger Kit. This is the second version of the battery charger, and it's designed to seamlessly work with the EPS V2 and V3 systems. Simply connect the EPS Power Unit via the EPS Charger Cable (sold separately), have a couple cups of coffee with the Sunday paper, and get back out on the road. Please note that due to the V2/V3 Power Unit's updated charging port, this battery kit is not compatible with the first generation Power Unit and charging cable.
