Battery location

Featured Replies

So as I’m working on this thing. They had the battery in the back starboard corner. I’m debating moving it to the back of the front compartment? I’m looking at the minnkota wiring chart and have a full understanding of 12 volt electricity and voltage drop. It would’ve a shorter run for the bow mount. And I would use the existing wiring for the transom mount motor. It’s 6 gauge wire plenty heavy. But roughly at the max for that length of wire. And that would have the battery roughly at the center of the boat instead of the back? What’s everyone thoughts? It’s a 26 pound lithium battery.

Put it where it is convenient. The weight is immaterial here. If you put it in the front then keep your tackle bag and lunch box in the back. Not sure what connections come on the Edge (if that’s what you stick with). If it is o-ring connectors then put the motor in the front and wing nut it on. If it is plugs then you’ll have to wire something anyway to make it convenient.

That’s a great point. Honestly hadn’t thought where I’d put that stuff other than on the floor next to the back chair. I believe it’s o ring connectors. But I can always add a plug to it. The boat doesn’t have a breaker in it. So I have to add that anyway.

But with the trolling motor being mounted and no quick disconnect mount why bother with a plug lol I could just hard wire it.

I'd be trying to keep the deck free of clutter. Open deck space bow to stern as much as possible to make it easier for humans moving around while fishing and not stepping on things like batteries and fuel tanks.

If it were me, I hide all that stuff as much as possible.

And I don't want all the weight in the back either. I use the fuel tank and batteries in my boat to balance it out better so I moved those to the bow under front casting deck.

I over powered my boat and the motor can push it to porpoise some even fully loaded, but the more weight I can shift forward the better in my case. I'm sure you will be adjusting yours as well as you learn it and want to change things.

As for the wires to the back you said are 6 gauge? AI says this about its current carrying capacity:

"For a 50-amp trolling motor using 6-gauge (AWG) copper wire, the recommended maximum length is generally up to 15–25 feet (one-way distance) to keep voltage drop within an acceptable 3% range."

I bet Minn Kota says less length than AI.

And when I look up the actual current capacity of 6 gauge this is what AI says:

"6 AWG copper wire typically carries 55A (60°C), 65A (75°C), or 75A (90°C) depending on insulation and NEC conditions, often paired with 50-60A breakers for residential use."

Most 55lb thrust 12 volt trolling motors can draw around 50 amps at full speed and with weight of boat loading it. Point is, 6 gauge wire is rated at or slightly above a trolling motor's maximum current draw. It should be fine. Be sure to use a circuit breaker and maybe a steel box for that battery. (I'm not a fan of lithium batts)

It looks like a new boat all cleaned up!

I’ll probably leave it in the back. Only thing that will really be sitting on the floor is some tackle and rods. And on the front deck the trolling motor pedal. It shouldn’t be to cluttered. Am I don’t want the battery under the front deck because it’ll make stuff harder to get out I think. but we will see how it floats and all that.

Oh absolutely. It will be fine just making conversation with the random thoughts in my head haha

I'd leave the battery in the back. You'll have no problem with 6 gauge on a 14' boat.

That’s honestly what’s gonna happen moving it will just not be worth it lol

I’ve got 2 group 24 batteries, (one trolling, one cranking), plus 6 gal portable fuel tank under the rear deck. 15 ft aluminum boat.

This how it sits it the water without anybody in it. I have had another person drive the boat. I moved around during takeoff. It really didnt change getting on a plane time at all, less than a second of anything.

I had a 12/36 flat bottom with a tiller controls, I realized where was at affected it more than anything. With me and the motor being all the to the back made it slow getting on a plane.

PVC extension on the tiller put me midway in the boat. My weight up there made a lot difference.
