Would it be possible to charge my a/c battery bank via an isolator? My a/c bank is two 225ah 6v in series. Currently the boat has two 12v in parallel for starting/stereo (from factory). Would all that be too much of a strain on one 70a alternator? Edit: nevermind. No. |

Personally I would not have the stereo wired to the start batt. I would have it on your house bank. Now you 2x6v house is 12v 450ah, I would tag the stereo on that so start is isolated. The amps used for starting are replenished fairly quickly while running around. The isolator only charger one bank at a time. Either the house or the start so it is "technically" charging one at a time. Now this said once start is replenished there is no need to put power to it unless there is a draw at the starter. So once it it topped off all altinator power is going to your house bank. And you are fine power wise with a 70. Not pushing it too hard. Now is both banks were dead and not isolated then yes you would be pushing too hard. Isolation protects the individual banks and also preents balance charge drain of a full bat, and allows lower strain on altinator. Adding an isolator does not add any additional strain to the alt. |

I would use a battery combiner, isolators have a .6V drop so your batteries never get fully charged. And I agree, I would not use the same battery's to start and run anything else. Forgive me, but no "Now you 2x6V house is 12v 450ah" you have 12 volts at 225amp hours. There connected in series. You double the volts but the amps stay the same. If the were 2 12v batteries, than yes, 450ah. That's a lot of weight!! |
