charging three batteries

[RangerDangerV2 5,000+ posts]

Well right now I have two xs d3100's and my stock battery with a mechman 270 amp alt. The question is can I leave the stock battery, hook that up to the alternator, and then take and wire the 2 d3100's independently. SO instead of wiring all three in series what I am wanting to do is to keep the stock battery seperated from the d3100's, and then of course wire the d3100's in series?

You better not be wiring any of your batteries in series dude..

You're wanting to wire the d 3100's in series? Why would you do that? What amp do you own that runs on 24v? What alt is going to charge them at 24v?

The batteries won't charge themselves so if you are burping at 24v you will be good for a single burp and then you'll need to recharge them.

correction parralell... dont need 24 volts, sorry.

Any way you wire up the three batteries, they will be paralleled eventually, unless you have a separate alternator charging JUST the D3100s. You can use an isolator, but I'd just parallel all three of them and let it smash.

But will the stock battery be able to charge the d3100's quick enough?

The stock battery doesn't charge anything.

no but you'll survive for a while. Get a nice voltage gauge and don't let it fall below 12.6v.

what should I add for 5k daily?? I already have a voltage meter.

I just told you.

I meant should I add another d3100 or what?

I would replace that stock with a good AGM. Are we talking 5k burping or 5k daily?
