24volt troller and charger

[hokie]

On 2008 Carolina Skiff 198dlv I have 2 red and 2 black wires. I have reds to positive and black to negative on each battery. They don't have a jumper and aren't wired to each other. Does the plug have the jumper? I seem to have 24 volts. Troller says GOOD in power. Can I charger without unhooking wires? By just unplugging troller? Can I use a two bank charger?

Hard to answer without eyes on the wiring itself - there are plugs that do the jumper function so that's likely what you have - I don't like those personally.

Two-bank charger is what you want - connect a bank to each independent battery - even if you had the batteries in series (without the plug) this is what you'd do. It's a good idea to disconnect the plug when charging just in case, but most don't.....

Thanks! I'm looking at on board chargers now. Charging is often the reason I can't go fish on short notice.

Hmmmm. I've always just hooked my batteries in series. I've never thought anymore about this.

It seems to me that your plug must have 3 wires (2 12 volt and 1 ground). The motor must use 24 volts for power and everything else uses 12 volt? Is this correct?

If so, I guess my 36 volt motor has internal circuitry that reduces the supplied 36 volt charge to 12 volts for everything but the motor? Is this correct?

If all of the above is correct, then I like sending 24 volts from the battery on 2 wires versus sending 2 12 volt charges on 3 wires. However, your motor probably won't allow this?

Hmmmm. Why do we have a main big pipe ran throughout our home where smaller pipes are then connected to it to supply water to various water outlets? My guess is convenience and less overall pipe and elbows and stuff. We could certainly run a bunch of smaller pipes to the source and this could actually be better if all the outlets running at the same time was more than the main pipe could handle. In other words, if you overtax your panel, by hooking up a bunch of new electronics, you might consider hooking up the new stuff directly to the battery. Okay... I feel better now.

Someone please verify/correct.

Limiting my fishing freedom would be unacceptable to me. I use the biggest batteries I can find (series 31). My batteries allow me to go nuts all day long and would even get me through half of a second day. However, I religiously make sure I keep them charged when not on the water or when at the dock.

I have considered an on board charger (one that uses the alternator, not one that is connected to an outlet) when I used smaller batteries but ultimately have found that bigger batteries do the job and really don't cost much more than smaller batteries. Secondly, I tax the living crap out of my house batteries and don't like the idea of stealing alternator juice from them to maintain my tm batteries.
