I would like to put an aux battery in my truck for off road lights and winch. I have everything figured out except charging the aux battery. Any help is greatly appreciated.

 

Not sure how its set up but they make a kit that hooks the two batteries together and keeps it at 12 volts. The kit allows the alternator to charge both. I don't know what year your truck is but maybe this will help. http://chevy.off-road.com/chevy/arti....jsp?id=200828
