Antigravity battery

Can’t believe how small and light it is yet packs the power. A must if you are tricking out your bike

Battery

Fit very well in my project. Only complaint is the battery doesn't have built in over and under charge protection like some others.

The fit and finish of this battery is sterling and it is has held it's voltage at 13.1 volts since the day it has arrived. This was a concern as I could not start my Norton to recharge the battery until the custom single axle assembly returned from my machinist. I'm very satisfied with this purchase.

100% impressed over and over again by Jeff & Co at Revival. They’re patient and kind no matter the enquiry (currently resto-modding an R100/7 and have LOTS of questions about the Motogadget rewire) and go out of their way to offer creative solutions and out of the box thinking. I will forever return and recommend Revival.

I cannot recommend Revival Cycles enough. Not only do they have a great assortment of gear and accessories but they provide superb customer service. I was having some difficulty making it work... Jeff pointed out what I was missing and also provided schematics to make it work. Thank you guys very kindly, your crew rocks.
