I got it from mcmaster carr. They have tons of different batteries, just find the right voltage/amp/size They are really reasonable too. This one was under $25 bucks. The place I used to work used them all the time for computer UPS systems (uninterupped power source) They are pretty sweet! Completely sealed and matinence free. You can mount them in any position and they are ment to be charged and drained 100s of times so they last for ever. My bike is goin to be kick only so it only has to power the lights and ignition. I dont think this would be a battery for running electric start.
