I'd like input from those that have converted to Lithium batteries for your trolling motor batteries and what charger you are using with those batteries?

Looking at this upgrade too, prices still look to high to make it feasible, unless ordering direct from from china.

Look no further than Ionic Lithiums from Andy at Drewcraft. You can get 3-50amps and possibly use your existing charger. Just let Andy know at Drewcraft what charger you are using. I use my minnkota precision charger. I currently have the 3 50amp and they have performed awesome. Why this instead of one 36v or 24v lithium? Should one have an issue for any reason, you can just drop another 12v in its place and keep on going. Big plus.

So the main reasons why I chose Ionic:

1. Can you use my existing charger without buying another, big savings there.
2. Can drop a lead acid 12v in ones place should an issue ever occur with one of the battery's
3. Love the blue tooth technology to check the percent of battery life left

Mention my name, Donnie O'Neal and he will give you great deal.

I have no recommendation but you might visit Bass Boat Central where there are a couple of threads on this topic.

Commerical interruptions are the worst. Seriously though, 50 amps is about half of the amps from a standard lead acid deep cycle trolling battery, the 125 amp is over $1000. Even if the last over 10 years, you could still stay under that price point if you bought new 50 amp lead acid battery 2 years and still not hot the break even point. Why would anyone pay that price?

For. 125 ah battery to make sense, assuming a warranty of at least 5 years the price would have to be at the most $500, and around $225 for a 50 amp. Big lipos just don't make financial sense yet for american retailers, but then again from unit cost I'm sure they are marking them up 400% from chinese suppliers, and that from what I've seen alibaba.

I have AMG batteries, but reading here ah on a lithium is different as they hold their initial state where lead batteries don't. And 50 is supposed to be plenty for 1-2 days heavy use. I've never made the switch but there was another thread on this topic recently.

When you start using a Lead Acid battery the voltage starts dropping.

As the voltage drops the amps go up.

As the amps go up the more drain on the battery and the more heat produced in the trolling motor and the wiring.

That, and loose connections, are why you see people asking "Why is my terminals and wiring melting?" and other problems from a bad wiring job.

I really didn't ask for a debate on Lithium batteries. I've seen them in action and I know what they can do. If you don't want to upgrade and your happy with lead acid then keep doing it.

What I asked for was input on a charging system for them.

You might want to do a little more research before you make a sideways remark to someone posting their story of their actual experience related to the topic. I also bought 3 50Ah batteries from Drewcraft for my Trolling motor. This was after using the 135 Ah cranking battery for the last 6+ months to see how it worked. Not only did I take about 200 pounds of weight out of my boat, I also got SIGNIFICANTLY better performance. I can list example after example but the easiest is to look at your remaining charge after usage. I fished a small 50 acre lake for 11-12 hours over 2 days without charging any batteries over the holidays. I only ran the big motor to launch and get out of the water. I run 2 12" Garmins, Force TM and Livescope, which if you've read anything is a big battery drain. Well, I connected to the batteries after these 2 days and the cranking battery was at 72% charge and the TM batteries were all at 74%. Add that to the weight difference, 7 year warranty and about 25% more space in the back of the boat and it's a pretty easy decision, at least for me.

Forgot to address the charger question. If you have a newer precision charger where you can select an AGM setting that delivers enough amps while charging you should be fine with it. I alo have the MK Precision charger like stated above and its charges them great. If you don't, then Relion sells their own charger for about $250 if I recall.

I'm often busy at the shop but anyone can call below and I can give my spiel on lithium batteries. We are an Ionic dealer as well and are cost competitive. They're excellent. We love them for the weight loss, cause GO FAST! Ionics have the neat phone app. Lithiums hold amp hours a little differently than lead acids as well. 50ah is sufficient for all but the most serious trolling guys who I have go with the 100ah. I personally am actually only running 2 35ah batteries in my Allison. I've never killed them, however I'm not that serious of a fishermen. An 8 hour tourney day for me happens every once in a while but is rare. I run a stealth charger.

I have been using 3 50ah Ionics for about 6 months, 36V Ultrex. Lowest I’ve gotten is 68% and that was last week in strong 20-30 mph winds using spotlock, fished for over 7 hours. Usually I’m at 80% plus after 8 hours of fishing. Unless you’re fishing in strong current the 3 50ah batteries are more than enough I think. I’m not sure how the 24v trolling motors and 2 50ah batteries perform so that might be something to research or someone else to give advice on. I’m thrilled with the Ionics so far and really like the Bluetooth app.

As far as chargers I’m using the same MK Precision charger I used before I got lithium’s. After a full day of fishing the lithium’s charge very fast, another thing I like about them.

I understand your not suppose to charge them till they get down to 40% at least. Is this true?
