re: Lithium trolling battery

I remember it was on boat forums, but here is a related article:

Lithium Batteries With Trolling Motors?
This is a common question we get due to the increased popularity of Lithium batteries today. You can use a lithium battery but your LED meter will not work on your trolling motor. Please keep reading for specifications you should look for when purchasing a lithium battery.


Similar to all other trolling motor brands, we also advise against using lithium batteries with our products. Lithium batteries tend to run at a higher voltage for longer durations (14-16V) than Lead-Acid batteries (13V). Trolling motors are designed to be used with batteries that output around 13V at most and then primarily 12V. Using a higher voltage can put wear and tear on the motor and potentially damage some of the internal components and ruin your motor.


If you can find a "12V" Lithium battery with an output rated less than 13.8V, this could safely be used with the 12v trolling motors we sell. Our 24-volt trolling motors can be used with "24v" lithium batteries with an output voltage below 25.6v.


The output voltage of a lithium battery can be difficult to determine, so you will have to find the battery's specifications or reach out to the manufacturer of the battery to inquire about the "Output Voltage." You will have to make sure it's specifically labeled as "Output Voltage" and not the "Nominal Voltage" of the battery. Many Lithium battery manufacturers will label their batteries as "12V" when they output a much higher voltage in reality.

Just bought an Ionic lithium 100 as my electronic battery. It powers 4 Lowrance depth finders and Active Target. Nice to have all 4 units with a voltage over 13 the entire fishing trip. Makes a difference in picture quality for my active target.

I have 3 50ah Ionics that I have run for over two years. Zero issues and never worry about running low on power while fishing.

That website is complete bull shite.

No 12V lithium battery I’ve ever looked at has an output voltage of 14V - 16V.

They’re doing nothing on that site besides trying to sell their own brand of lithium batteries. Everything they state is complete bullshite.

Interesting it’s on page 40 of the Ultrex manual here: LINK

However, I have an Ultrex and I’m looking at my manual now and it says nothing of the sort.

Also, my voltage output and current numbers from my lithiums are very similar to the agm battery I had before the lithiums.

I’m gonna call minn kota again and ask what has happened recently.

Running the bass pro lithium 80 ah batteries now. Made my Relion. I figured if I do have issues, I can bring them back to a local store.

Also using a lithium cranking battery I found on eBay. Has been working great for 3-4 years. No clue if my 90 Yamaha 2 stroke charges it, but it’s never died on me. And It’s pushing 2 JL 8.8’s with an amp that I play all weekend at the camp.

O and as far as running the trolling motor waive open for long periods of time… I got stuck sight fishing last week and had it on 9 -10 about for 15 minutes strait with no issues.
