I called the manufacturer but all I got for a response was it will void the warranty.

Here you go right here. Minn Kota makes this very easy. You just need a way to crimp this and then heat it up to heat shrink. If you forget to put the heat shrink on, just get some electrical tape and wrap up the wire in that to cover it up and then blast a heat gun on it. https://amzn.to/2YqkCri

If you do not have something to strip the wires and crimp the splicer butt connector, here's a tool that will help you do that: https://amzn.to/2Y0Z3yj

Smart move. I am surprised that you were not offered the extension cables as a solution when you spoke with the manufacturer. Poor service? Vote with your feet!

If you don't have faith in your skills then purchase the extension leads.

I am putting a charger in my boat for the first time, I have a house battery in the bow and a cranking battery in the back. Both are wired together so when my motors are running both are charging. The issue I have is that the two batteries are approx. 20' apart and I cannot centrally locate the charger. So do I extend the lead with 12 AWG wire to reach 20' or do I just hook the charger up to one battery and it will charge both? Not sure what to do with this set up?

I would MUCH prefer both batteries to be independently charged by a 2 bank charger or use 1 charger for each battery.

Technically yes it will charge both, you have them hooked together so it's really just one big 12v cell anyway. But , I'm with Bobby on this one, get a 30 amp, dual bank charger, extend one set of leads and charge each one independently. That way each battery is getting 15 amps and charging alot quicker than letting one bank charge both.


Also do you have a switch to isolate each battery? I ask this because if one battery starts to have problems, say a shorted cell, if they are connected it will affect the other battery. I'd have them on a switch, connect them while outboard is running to charge them both then isolate them when the big motor goes off.

I'm looking at a 2 Bank, 20 AMP Charger. So run one lead to the house battery and extend the other lead to the cranking battery, approx. 20'? Yes I do have a switch and can separate them when the bog motor is off.

Use a combiner switch ($70) on the cable connecting the two batteries. A combiner disconnects the batteries when there is a demand so that the crank battery doesnít discharge when a load is on the house battery assuring reliable engine starting. The combiner closes when the crank battery is full and charging so that the house battery receives a charge when the main engine is running.

Since a combiner allows 2 batteries to fully charge when a single bank shore charger is used, it is not necessary to add a second bank charger or another single bank charger. Consider that optional. The most important element is the combiner for safety, best performance and longer battery life.
