![]() ![]() Its commonly used for applications involving solar or other onboard charging systems, including generator/alternator charging, where battery bank amp monitoring is available. BTW, add a true deep cycle, not a dual purposed battery, which is what you should have been using in your single battery config.A battery isolator is a diode.a one-way only path for electrons on their way out of the battery, never to return again. Ground (common) is common (ground) everywhere. Think of each battery as an independent system. When you add the deep cycle, ALL the electronics goes on it and only it. I see Overtons has a sale on "Charles" brand chargers.anyone with experience there?My boat usually sits in the driveway 1-2 weeks between outings.would a solar charger (or two) be applicable?Finally, should I put all the "other" electricals on the deep cycle, and keep the cranking battery ONLY for starting?Ībsolutely split the batteries. I lean away from Guest/Marinco, as all Marinco products I have ever bought have been complete, utter, total, outright, undivided, thorough, and unqualified CRAPOLA. So the answer appears to be.Forget the isolator, and forget charging both batteries simultaneously with a single-bank charger either lay down the cash for an onboard two-bank charger, OR trickle charge each battery separately with my existing single-bank portable charger.Is this the consensus?Any recommendations for a good brand of 2-bank onboard charger?I lean toward Xantrex, as I have heard good things about this brand. Re: Battery Isolator, Charging, 2-Battery System All other electricals (lights, VHF, sonar, etc.) are attached to this battery.I want to add a second, "Deep Cycle" battery to operate a 12v trolling motor.The guys at Mercury tell me that the O/B charging system puts out "40 amps no load, 100 amps cranking."Question 1: is this enough juice to charge both batteries through an isolator, especially considering my usage pattern?Question 2: what capacity isolator would I need? Is 42 amp enough, or will this burn out during cranking?I know I should put down the bucks for a 2-bank onboard charger but I already have a portable 1-bank 2 amp/10 amp charger I ought to be able to use.Question 3: can I charge the batteries through the isolator using the single-bank portable charger? If so, do I have to disconnect anything else? Can I connect the negative posts of the two batteries together to ease hookup of the charger?Question 4: should I connect the electricals (lights, VHF, etc.) to the cranking battery or the deep cycle?Thanks. ![]() It is likely that the motor will never be at WOT for more than an hour at a time.I currently have a single "Cranking" battery. I use the boat to run around local lakes and bays, and I would like to be able to go just offshore (1-2 miles out). Hello all,I have read the numerous threads about 2-battery systems and isolators, but have not found anyone addressing my specific questions.My boat is a 15' tri-hull with a 70hp 1978 Mercury O/B. ![]()
