Location: Eastern Ontario | I am thinking of changing my trolling motor set up from a a 12 volt to a 24 volt. I was told that with two 12 volt batteries in series you could still charge them with a 12 volt charger by puting a trolling motor plug on the charger leads and plugging into trolling motor socket. I can see this if the batteries were in parallel but unshure this would work in series. Opinions Please

Location: Eastern Ontario | So whats a Marinco system and how does it differ from any other plug set up? Can you also explain how it is possible to charge what is esentially a 24 volt battery with a 12 volt charger? |

Location: Grand Rapids MN | They're not 24V batteries, just 12V in series which output 24V together. If you split the feed from a 12V charger to two 12V batteries it will be fine. Remember two 12V batteries in parallel will have a 12V output; you are doing the same thing in a sense with the charger, splitting the voltage in parallel circuits. |

Location: Eastern Ontario | But by just plugging into the trolling motor plug are you not trying to put 12 volts into a24 volt system I'm still not understanding it ?

Location: Rhinelander, Wisconsin | The panel wiring and plugs for a Marinco system allow for the accessing 12 volt to charge both batteries with the 12V plug, and 24 to feed your motor with the 24 volt plug. I use a 15 amp battery charger with the red 12 volt plug to charge the batteries for my 24 volt MotorGuide. |

| What Steve describes is correct.
Now, if you have two recepts in your boat, make sure the 24V TM is unplugged, or you'll pop breakers/blow fuses. I carry a 12V plug with jumper cables wired to it so I can jump my main battery, or someone else's if required. |
