Minnkota 12 vs 24 volt

[jusfloatin]

I will be adding a trolling motor to my boat it will be an engine mounted model that mounts to the cavitation plate.
I am fully prepared to have 2 batteries designated for the troller.
My qestion is I can get a 24 volt model for substantal discount but would I have to have 4 batteries to last as long as a 12 volt with a back up.

Hope that makes sense enough.

Re: Minnkota 12 vs 24 volt

We have no idea how big your boat is or what size motors we are talking about. If you want back up for a 24 volt motor you need four batteries. It doesn't matter how long they run. If you have a 12 volt motor and you want backup you need two batteries. The 24 volt motor will run longer on the same amount of available current than a 12.

This type of model starts at 55lbs and goes up, the boat it will be pushing is a 16' closed bow deep v.

I realize that it is way bigger than I require but when I can get the 24 volt model for $300 dollars cheaper than a 12 volt.
I have to ask and see what to expect and no better place to ask than right here on Iboat.

Maybe a better way to ask this question is, can I expect a 24 volt trolling motor to push a 16'closed bow deep v with 2 people and a minumum amount of equipment (100 lbs) for 8 hours.
I would be using Optima blue tops for batteries.

I'm going to pass on this one for the simple reason I don't see having four Optima's in 16 foot boat, with a closed bow no less, or the need for a 24 volt motor even though it is cheap. Four Optimas are not cheap and they are heavy. The only reason I could see for a 24V motor is if you intend to run at some speed way above what a troller would normally be used for. You have not identified the requirements for purpose and speed so the 8 hours is of little help. Even a 12 Volt bow mount will run eight hours on two batteries if you are not running wide open all that time. I have a 55PD V2 on an 18 foot pontoon and it will run all day. But it does not run on high speed unless I need to quickly turn around to get a line unsnagged or to move a short distance.
