Re: Battery Combiner for each motor?
The battery combiner from the second charging source can shut down its attempt to charge the house battery when it senses the higher-than-battery voltage coming in from the first combiners charging voltage. Normally, two independent smart charging sources on one battery do not always work unless you are combining the outputs of a single dual-bank charger that is designed to sense the combined outputs.<br /><br />A simple solution would be to install a deep cycle house battery that is big enough to provide the amp hours you will need during a typical boating session then re-charge it using a 120vac charger when you return. In your case it may be as simple as adding a second, identical house battery in parallel and an appropriate battery charger. You can leave the battery combiner on there, it doesnt hurt anything.<br /><br />Alternatively, you can toss one of the new AGM deep cycle batteries into your boat for a house battery. They can accept a charging rate of C/1
capacity-over-1
that means a 120A/Hr battery can be charged at a rate of 120amps. You would think the battery could be completely recharged in 1-hr but the battery resists the charging voltage as it fills up. It takes about 1-hr and 15-mins to completely charge a complete flat battery. Depending on your alternators output, you may need to install a bigger, beefier alternator to keep up with the battery.<br /><br />There is a guy in Fort Lauderdale, Florida that can help you with what you are trying to do.
