While discussing my battery problems with my 2015 epic SE, a friend of mine mentioned that there was a way to use the old battery as a power supply for less demanding applications. while the battery may no longer have enough power to run the bike it can certainly charge phones and tablets perform and other less demanding applications. Anyone heard of anything like this? I was told there is a way of connecting a USB charging port like they have on the 2016 and newer EJoe models. would love to hear comments on this from the forum. Thanks.
