Lithium batteries for trolling motor?

Use a fully charged battery ( AGM, acid filled or another lithium ) and hook your jumper cables from the host battery to the lithium. Put the charger onto the lithium and it should start to charge. Be sure to remove the host battery after about 15 minutes and the lithium should now charge.
I have also been told to boost the dead lithium with my truck or any charger that kicks out 14.5 V. You just need to get enough power to reset the BMS

I thought this strange. Since Dakota says there 36v charger will wake a sleeping BMS.

But I did find this info online and tried this before I posted. It did nothing.

The battery isn't waking up.

Dakota has made contact and is making it right. Sending 3x 100ah 12v lithiums and wiring pigtails for the 36v ulterra at no cost.

Its a known issue between minn kota and dakotas 36v batteries they are working to resolve. Would have been nice to know ahead of time and not be scrambling before my yearly trip up north but that's what this post is about.

Just a word of caution anyone considering this battery. Go with individual 12v batteries instead.

It is weird as my original powerdrive would also troll for hours with no problems.

how big is the boat .

I used mine for 5 hours straight every day for a week but the Dr said not healthy for big boat . maybe the 10 time it might burn up ...maybe the older units have brushes . never looked inside yet .

My boat is a 20 foot Crestliner.

I put thousands of hours on 24v minn kotas mounted on a 19 foot lund. Never an issue.

The vast majority of guys running 36v in alberta could get away with 24v no problem.

Myself included.

This thread has made me think I should change my lead trolling motor for Lithium.

I found these batteries on line. They considerably cheaper.

Does anybody have any feedback or experience with these batteries?

Lots and lots of YouTube Videos showing many brands of 12v LPO4 battery's being stress tested and opened to check build Quality. They are pretty definitive on which are good and which are not.

I changed my Lead Acids on my camper to 2 12v 100ah LPO4 I'm cheap bought the DC House brand of of Amazon at the time I paid $278.00 each.

Eco Worthy is selling their 280ah single unit for $783.00 as of this date. 05/30/2024 Not as good a price per watt as the DC house but will recoup a bit of $ with lower cost due to not having to cable multiple battery s in series or parallel configuration.
I'm thinking I might make the change and use the 100ah for running trolling motor on car-topper.

I have been thinking of making the change on the trolling motor battery as well. My bow mount is just a Minn Kota Edge. I will get 6-7 hours on a standard deep cycle and it will be dead. What kind of real world run time can I actually expect if I switch to a 60Ah Lithium? (I know it depends on many things), and is it worth the extra money to go to a 100AH? As long as I can get a full day I would be happy so not sure if a 100 AH is worth the price difference if a 60Ah will do.

The more AH the better. Not a lot of difference in price or weight.
Remember the one thing about Lithium is they "run at full power until they are out of power".
I have an Ulltera bow mount which requires power to store. I have been caught only once (learned a lesson here) when the bow mount would not store due to batteries being depleted.

I'm running Canbat lithium trolling batteries. No complaints to date but I don't use my tm heavily anyways. It gets the odd day here and there so a pair of 50 AH batteries with bluetooth serve my needs. If I was running weekends at a time I'd have gone with a pair of 100 AH. I'm connected to an Xi5 80# 24V motor and installed a NOCO 3 bank 30AH Smart Technology Charger to my Lithiums and lead acid cranking battery. It can charge both types at the same time as it has sensing technology for different battery types to send the proper voltage to each type. Bought it at Radioworld on sale $200 off. Works fantastic.
