Lithium Battery for Trolling Motor

[Mr. Pike]

Bought a 100 ah lithium battery for my trolling motor and ran across this article. I should probably run the trolling motor in my driveway to see how long it lasts before I head out.

Should last about 5 hours according to this.

I have an Eagle fish finder mounted up front that I also use.

It was the year 2023, Mr. Pike got caught in the wind and accidentally nuked his electronics.

 

[Mr. Pike]

Shouldn't damage electronics. I have a fuse in the line for both trolling motor and fish finder.

one thing with the lithium battery's in tools is they just die, dont slow down just die.

Yes. Exactly. Mine lasted 4 hours the other day on Sacajawea. Was constantly trolling. When I got home, I put the volt meter on it and it read 11.5 volts which is completely dead. I put my 20 amp lithium charger on it and it only took 1.5 hours to get it back up to 13.5 volts, which is a full charge. A lead acid would have taken all day to charge.

Was looking at a Weize 200 amp battery for $600, but they weigh just as much as my Interstate lead acid.

I'd be pissed if my batteries were smoked after only 4 hours of fishing.

I have Triple CAT batteries running my 110, they each weigh I would guess 50lbs, Its a real treat changing them out.
