I am in a unique situation where I have no access to a 230v wall socket to attach a battery tender. My plan is to use my car which is parked right next to the motorcycle to keep it charged up. In the past, when my motorcycle has refused to star, all I had to do was hook it up to my car battery, not try to jump start it but just leave the two hooked up for a few minutes, disconnect and then the motorcycle would start without any issues. In this case, I am attempting to make a proper charger with trickle charging capability. I want the input to be a car battery (11v to 14.4v 32A) and the output side to be a steady 12v 750mA to 1A to keep the motorcycle juiced up.
Do you think I'm on the right track? If yes, would someone be kind enough to help me out?
