My 2012 uses the same charging components as well as the same battery. I have not modified them.
I would take a pic of my Shorai as I wrote in the date of purchase, on its top. It's dark, and I cant get a decent picture.
The date says, "2-11-2013". I always said I would replace it at the first sign of trouble. So far, it's as good as new. The secret is to ignore it. It doesnt need to be charged to 100% to be excellent at starting the bike. I did buy shorai charger. I've used it 4-5 times for winter storage. Sometimes I dont even do that. Just ignore the battery. People cook them by trying to keep them 100% charged. My battery has never needed to be balanced.
Its lighter, obviously, and smaller than stock. Shorai gives you some high quality foam so you can make it fit without moving around.
Old bikes may have caused problems for these batteries, but mine never has.
