Going Lithium.

[volsdad]

I am real tired of replacing lead cell batteries every year. I am going to go two 12 volt to get 24volt. I have a lowes pontoon set up to troll for crappie.What I am asking is what AH do I need. Would a 50 or 60 AH work for this? It is a fairly light pontoon 19 feet with a115 on it. I bought aNocoGen 5x2 2bank 10 amp charger to put on the boat. I am assuming this will all work.{Please advise !! Thanks in advance

It all depends on what your current battery set is and how much you use in a typical fishing trip. For example, I currently have two Bass Pro group 24 AGM batteries that have a 75Ah rating, and my 24V Terrova moves my 18’ bass boat around using only about 25% (can’t recall seeing my battery indicator showing 2 bars since installing them—I usually see 3 bars by the end of the day. Since I can run a Lithium down further than 50% to keep from hurting the batteries (probably down to no more than 20%), I should be fine with a 50Ah Lithium battery (either 24V or two 12V in series).

*NOTE: FYI (as I understand it)

If you read the NoCo pamphlet it will tell you that only lithium batteries with a BMS are recommended to be charged by it.

At least that's what my NoCo GenPro 10x3 pamphlet says.

You will also need to keep the Lithium Iron Phosphate batteries out of direct sunlight and in a cool & vented space.

Maximum amp draw for trolling motor x operation hours needed a = AH size Lithium battery needed. What kind of trolling motor are you running.

I run two 12v 100ah LiTime Trolling batteries and have most I’ve run them down was to 70% left. That day I was scanning most the day and running trolling motor a lot. Could I have gotten away with 50 or 60ah, maybe but I paid $259 a piece for mine and rather have too much than too little. I charge with same charger you have.

Call Impulse Lithium and see what they recommend.

Not ever used lithium for trolling or starting . I been using Amped Outdoors 32ah lithium for 4 years for livescope set up and well pleased. There are 12 and 24 volt batteries out there . My guess would be use a 100ah or larger for trolling motors. I would talk to battery company and get good information on your planned use needs.

If this is true you might have other problems?

Could be charger or too small of batteries. Lead acid batteries pulled too low actually damages them. Better to have extra power than too little anyway. Keep batteries charged and wet batteries full of distilled water. Poor maintenance or pulling too low will kill your battery. I get several years out of Walmart batteries most of the time . Have gotten a bad one before but their big deep cycle batteries have 2 year warranty. EverStart-Maxx-Marine-Battery-Group-Size-29DC-12-Volt
