Dual battery setup

[98 2-DOOR]

Anybody have a dual battery setup, simple? Just need to add second battery for winch only.

I was going to use a setup like this on an old truck I had but I never got around to it. It uses a dual battery switch for a boat to separate both batteries for charging.

I've heard of problems using two batteries constantly. Problems charging, problems with different size/age batteries, etc. The switch cuts power to one of the batteries...less problems.

If Its easy enough I'd like to have two battery's one for constant use then one backup like in my boat. If anyone has done this please post!

I assume you want them isolated correct? I have not done mine yet need money but mainly I have not come up with a product that serves my specific needs without costing more then $1000.

yes, isolated...

 

[SunlitComet]

do you need anything like automatic charging control or dual battery amperage availability when say starting or something like that?

My question is would I need more than one alternator? Or will mine over charge the batteries and brake.

one alternator, two batteries at about same size and capacity and a basic diode isolator will do you just fine.

ok, so i went to a local audio shop and they said that all i needed was an isolator. so i pick up a 200amp stinger isolator, associated battery cables and connectors. i already upgraded my alternator to a 200amp, now all i need to do is hook it all up...standby...
