My suggestion was to throw 3 deep cycle 12v batteries along with a fully charged car battery, connect them in series parallel, with a combined amp rating around 360amp/hr Figure the motor is going to draw 20amp, so we should be fine for one day of fishing. Argument against was, dissimilar batteries, going to hurt them. My feeling is they're sitting around doing nothing anyway, not going to stress anything close to capacity, what difference does it make? Never tested a system yet (including forklifts) that had every battery perfect, so as long as they're electrically equal, what can limited use harm?

The only issue is the non deep cycle battery? It will work voltage wise. I’m not really sure if it will hurt anything. The only thing I wonder about would be sensitive electronic devices. Obviously a 24 volt trolling motor likely has some type of minimal board/electronics. I highly recommend using a proper 24 volt circuit breaker just in case of a battery failure which may drive some weird voltages to the motor. I installed a 12 volt minnkota CB on my trolling motor. On a personal note I wouldn’t do it. Good Luck Link to comment Share on other sites More sharing options... Awards

If you put two batteries in serial along with two others in parralel you gonna have 24V and then power amp hours gonna equal two only one side of two parralel batteries. lets say if you link four 12V 100Ah batteries serial/parralel youll end up with: 24V and 200Ah not 400Ah . and your weakess link is the regular battery along with his discharge youll have a loss of voltage too .

I didn't want to fill a page with numbers, You are correct. I will end up with 2 banks of 24v batteries, wired in parallel. My amperage will average out to 180amp, for an average runtime of 9hrs. Except we won't be pulling any amperage for any length of time. And yes, a 50amp breaker goes between batteries & motor. Link to comment Share on other sites More sharing options... Awards

Is it safe to mix battery types in circuit? A regular car battery isn't designed to be drawn down flat and be recharged like a deep cycle battery is capable of doing. Normally a regular car battery will supply all of it's amps in short bursts. The car battery could overheat and when it dies the other battery adjacent to it in circuit will be doing double duty. Something will eventually have to give. Worse case scenario 1 of your batteries could explode. Realistically though since you will be pulling a max of 50amp with an 80lb 24v Minn Kota trolling motor it should be just fine. Just bring a volt meter and keep an eye on battery voltages. If the car battery starts to run low unhook it from circuit asap and get your butt back to shore. KaptCrunch and major-mark63 2 Link to comment Share on other sites More sharing options... Awards

Jester correct the car battery will take you down to the bottom of water TLCB also use minuim 10 gage wire your good up to 60ft before wire becomes a heat element after that. when you get in the water and use motor check connection / wire for heat ..don't touch wire if see it melting you can add a disconect switch to circuit Edited October 20, 2021 by KaptCrunch Link to comment Share on other sites More sharing options...

End of season quickie to a wake-less local lake. Not huge, but lots of coves. Bluegill are tiny, going to spend a lot of time laughing about the children we're catching. Shore Gestapo gets all bent out of shape about wakes & speed. They'll barrel down on you with their 100hp Merc @ 30knots, swamping everything nearby if you break their association rules. Hence, the 16' Alumacraft & trollers. Using what's handy & available for ONE day of leisurely fishing. Gets dark here around 18:30, so it won't be a forever day. I did have to laugh about melting cables & exploding batteries, holy shite folks, did I not mention this isn't a power trip? Not my first day playing with electrons, and I'm quite used to operating sub-par setups. Nothing is getting stressed, particularly me. rexbowan 1 Link to comment Share on other sites More sharing options... Awards

They are not built the same way. Quite correct, and I wouldn't consider using them in a full load, extended use condition. Car batteries are amp intensive for a brief period, they don't care for long draws, even with minimal amp demands. This was a once only consideration, but got shelved when I was reminded of the 12v trolling motor hanging on the wall. I have no problem using a car battery on a 12v troller, because we've never made more than a couple of hours use of them. If they peter out...so what. I also use heaver gauge wire on a 12v system vs. a 24v, because you're drawing heavier amperage across a lower voltage. 24v gets the job done at lower amps, so less heat is created. I'm agreeing with everyone, using matching batteries for one system, a single battery for the other, because it's a safer option.
