So what's the deal? I hear that more power gives better images and then I hear that it does not. Is it more of a settings issue or is it somehow enhanced by more power? If so how do you give the unit more than 12Vs without frying it or when more power is mentioned it actually refers to larger AH? Planning on giving it its own lithium. Is a larger AH actually worth it or will a 50AH be plenty?

It likes 12volts. The idea is to make sure that there isn’t less than 12 at the end of the day. A dedicated battery ain’t always needed.

Any electronic device.. if it is working properly will only use as much power as it needs to operate. no more, no less. More voltage than the unit requires will fry the unit. You can provide a battery that has a higher AH rating, it just means that the battery will last longer.. not that the unit will perform any better.

Thank you. That was exactly what I was thinking but had not confirmed.

Get a Pro Guide 31AGM, always put your graphs on standby, and you will be fine.

It’s not more power like some sellers claim, it’s clean power. Dedicated lines that can handle the voltage.


Is 50 ah big enough, that depends on the graph being used with the LS.

I don’t believe it is more volts, or amps for that matter. But in the way of resistance, I was told to run dedicated heavy gauge wire for the LS and head unit. While they don’t warrant excessively larger wire with the amp draw, ensuring there is not excessive resistance is key.

Inversely don’t go too large or you can get voltage drop. Think of wire as a hose, and too little hose restricts volume, but too large hose lowers intensity (pressure)

You lost me on the water hose analogy. How is it that a car, using a VERY thick chassis as its ground, gets around this crazy hypothesis of yours?

To the OP….you can’t go too big on the cable, however there is a point of diminishing returns with every electrical wiring decision. I’d say 8 is about the biggest you could run without being called a Vexus owner. 10 is more than enough for most every graph on the market in multiples. Of course the connections have to be made correctly and kept free of corrosion.

I understand and appreciate the water pressure/ power comparison but I don’t think it’s acurate! I’m just a dumb ole plumber but I do know that when your dealing with a given pumped pressure you can increase pressure at the point of use by downsizing the line prior to distributing which will also effect volume which will turn to nearly nothing if you increase the pipe size before distribution. I was always led to believe it was opposite on electrical current AKA you could restrict the flow with undersized wire but over sized wire was not an Issue! Is low voltage different than high voltage? Is oversized wire an issue or just a waste of money? I think this would be very educational for some of us that like to do our own boat electronics!

I’ve always wired my own graphs and always have found it interesting how we are supposed to use large wire, but the manufacturer gives 4’ of a tiny spindly little 18g wire for their power cord. I make the power cord shorter, but one would think that for what graphs cost, they could spend $2 extra dollars on bigger wire.


I think the point that he was trying to make above, was that running 6g for a graph that pulls 3ah, would be unnecessary and a waste of money.

Some are using 18v and 20v dewalt and Milwaukee tool batteries with the Seelite adaptor. Voltage always above 12v so no voltage error, and the small battery(s) can be stored in the rod box right next to the unit so no long wires to mess with. From my understanding the max voltage on many of these range up to 20v. It’s a hack and appears to work. I know a couple of people running it with no issues.

Don’t run the Lowrance graphs on anything over 17v, I think the AT can handle more, just not their graphs.
