Dual Battery
 

Hi all, I have a XYKD 260-1, 260cc engine and I've made some small modifications. What I want to do is add another battery to run my lights and my winch. I have a battery which is exactly the same as the main and I have a 70 amp isolator. My question is this, I can't figure out which wire charges the battery when the engine is running. There's only one wire that goes to the battery, do I use that same cable to go to the alternator connection on the isolator? Working with a basic motorcycle engine is new to me. Does anyone have any suggestions? Thanks again.

I would just run a truck size battery for ur winch and extra. Lites and accessories by itself with a switch.and charge it after every use.. don't mess with your buggies battery system. I say this cause I'm no electrician.:)

Agree with Eddie. The greater load you put on the stator the more power you lose, and the greater your chances of burning it up. I think you would fare better hauling the big battery than you would trying to charge two batteries at once.
