need help with second battery


Recommended Posts

Posted

I have a 2000 Silverado single cab that I have built a custom box for with two tens . I just bought Audiopipe apcl-30001d and I am about to buy two skar audio ddx10 and I have a powersafe 12v190f battery.. the battery in my truck is an interstate and I am about to do big 3 and have all 1/0 gauge wire.. do I need a battery isolator? What would be best?

So how should I hook it up?.. I don't even know where I'll put the thing.. it weighs 130 lbs.. everything that I have read says to use a battery isolator because these are two totally different batteries and will cause infighting and premature battery drain

Ideally you should connect the batteries in parallel if they are the same kind. The resting voltage of wet cells and AGMs is different so the manufacturers recommend not to hook them together. That being said, there are several people here that have done so without problems. You should do a search because there are several threads here on this topic.

the battery with the lower resting voltage will drain on the higher resting battery until their voltages are level, which will potentially shorten the life of the (originally) higher resting battery. Besides that, nothing bad will happen as long as you fuse the positive near both batteries and don't short the positive to ground.

Ok awesome.. I mean I've been doing this for a while but I've never messed with 2 batteries and the powersafe battery I have I cannot find any information about it other than it's 190 ah and it is huge and weighs 130 pounds.. is it even worth the trouble to have two batteries? This is a $600 battery but I would almost rather just do big 3 and possibly alt if I need it..

Those amps are power hungry. I would do the battery and the big 3 and an HO alt.
