Default Lithium trolling motor batteries

A friend is putting a Minn Kota I pilot 24V trolling motor on his Maverick HPX-S flats boat, and wants to use a single 24 volt Lithium battery to power it to save space. What's the going best battery, and charger? I know very little about Lithium batteries except that they are expensive.

I run a 36 volt system on a bass boat. I stayed with 12 volts to retain the perko/ jumpstart switch function on my rig. I also use a 12 volt 80AH Lithium as a house battery..running outboard starts..electronics..pumps etc..one thing to consider is a 24 volt won’t have a jump start ability. As far as charging...you are going to need a lithium specific charger to get full performance from the battery. I sent a dual pro back to the factory to have all four banks reprogrammed for lithium. It was about $110.00 to get it done plus shipping.

Check out LBP. Top notch guys. I recently added a single 36v to my cape bay. They make a 24v 100ah that’s the size of a group 31 and should last all day or multiple. Delivery was very quick. 3 days from paid to in the boat

holy crap! Just looked at LPB and a 24v 75ah is $1000 plus another $500 for a charger!

I’ll have to pay the weight penalty for the 1200 savings.

(2) 12v Lithium Relion's the RB50's and a charger. Yes, lithium is 2X the money and 1/3 the weight, 1/2 the footprint and 5X the lifespan.

Ionic, here. Dual Pro charger. Awesome, awesome, awesome. Ionic has an app for your phone for easy monitoring. Also, went from 100ah batteries to 50ah lithium. Lithiums maintain their voltage throughout the charge. I have run them hard and used spot lock a lot and have yet to run them past the 70% mark.

I had the same dilemma recently. Li-ion batteries are cheaper long term. For my 84 rhodan we went with ionic 12v 50ah times 3. We don't need more than 50 amp hour as lithium batteries give full voltage to the last bit. lead acid batteries the voltage starts dropping off after a certain point so these batteries are equivalent to about a 100ah lead acid. We didn't do single 36 volt so that in case we have to use for battery start we always can tap into these. I made a small little battery tray that I can move this from one boat to the other with three wire simple disconnect. We use a yandina onboard charger that uses the alternator from the motor to keep them charged. I attach the charger to this battery tray so I only needed one for both boats. I don't think this setup weighs more than 38 or 39 lb

Ionics have a bluetooth app which gets raved about.

When my leads die I'll be in the market.

Here is a good read, 68 pages about Ionics.

Contact Matthew Lardinios at Amped Outdoors. He sells a lot of batteries to fishermen.

I'm very intrigued to go for it on the new boat. The benefits sound amazing.

There's a new company called "Fourvolt" that's taking preorders for deep cycle lithiums now at a reduced price. I believe it's about $400 for a 12V 100ah battery. I'm tempted to order but hesitant because they're so new.

Are those made here? You can get foreign ones at that price all day long.

Custom Marine Products has a Blue Tooth app, as well. https://www.custommarineproducts.com/

Didn't know we were voting, but Tom Trimmer at Custom Marine Products is great to talk to and I've talked to a bunch of different people at a bunch of different companies while researching LiFePo4 batteries. One thing that I've learned about these different companies is that many don't know and/or understand our (boaters, fishermen) needs and uses when it comes to these batteries. They're mostly targeting the automotive industry where people are putting extreme stereos and light systems in their vehicles.

No first hand experience, but like many I've been researching the topic as well. Here is another good 24v option- https://battlebornbatteries.com/shop...cycle-battery/

Love my Ionics. 2x 50AH 12v. Having the bluetooth app to view SOC is sweet

Would definetly recommend 2x 12v vs a single 24v for multiple reasons - ability to jump off them as well as cheaper/easier to install a charge on the fly system. It takes about 4 hours on the reef, without breaks to recharge in very heavy wind/current to kill my batteries with spotlock bumping 10 frquently. Otherwise, in a day of running around inshore fishing, I'm usually at 99%, but have got down to ~70% if I don't have a decent run otw back to the ramp.

Thats the same battery and source my friend is looking at. Because of the very limited amount of space in his boat, he wants to use single battery power for his 24v trolling motor.
