12V to 24V What to do About Accessories
I have a 12 volt trolling motor. I am going to purchase a 24V motor. That installation is pretty straight forward; i.e., install another battery and connect it in series with existing battery. NOW, what about my accessories such as electronics, bilge pump, live well pumps, navigation lights, etc? Currently they are all connected to one 12V deep cycle battery. Since that battery will be part of the 24volt (new) system, I cannot connect my accessories to that. The only choice I see is to connect accessories to my cranking battery. However, the cranking battery is not designed to run accessories, it is meant to supply a short burst of energy needed to start the engine (90hp) Mercury 4 stroke. There is no room to install another battery. WILL IT BE OK TO CONNECT ALL ACCESSORIES TO CRANKING BATTERY? By the way, all accessories are fused in a main panel. I've looked for solution on YouTube but they only show how to install the trolling motor and nothing mentions what to do about powering the accessories.

All accessories are supposed to hook up to cranking battery. Only the TM on TM battery. 24 volt wires like this
I have spent most my life fishing........the rest I wasted.

Hook your acc to cranking battery. If it knocks it down you may have to get a better battery. You could hook all your acc stuff to one of the trolling batteries but I’d put electronics on crank battery. Won’t hurt pumps and aireators to be on troller battery. You just have to hook them to one battery, pos and neg same battery. They will never know 24 is involved. If in doubt hook up as 24 take a meter and read pos- neg on one battery should read 12 volts.

I have cranking battery, acc battery and trolling batteries with a 4 bank charger. It may be overkill but I want my cranking battery to only be for my engine. I got to spend all night at the lake one night with a fella that run the aeration on the livewell and we couldn’t crank the engine because the battery was pulled down.

This is absolutely true. One word of caution- the extra pull on one of the batteries will create an imbalance in re to charging.Originally Posted by Cray

Everything is on my cranking battery . The trolling motor has two batteries to itself .

The battery with the most Reserve Capacity I was able to find was a group 31 battery from VMAX. It has 265 Reserve Minutes (Which I did buy to use as a electronics battery). Was'nt cheap though, but I found nothing over 200 minutes in the same size. My Bluetop Optima I have as a cranking battery has only 120 minutes. Look at my post (Best Dual Purpose Battery) regarding that and it may answer some questions. Good luck.
P.S. VMAX was $349 shipped.

"Cast your net on the right side of the boat and you will find some." When they did they were unable to haul the net in because of the large number of fish.
Maybe we are just on the wrong side sometimes.....
