Looking at prices on Lithiums today. Big jump from 50 to 100a. Trying to figure out if I really need the 100s for running the 24v TM half a day on spot lock in the wind. Money is not a big deal just hate to spend more then I need to. Also wonder if it makes sense to run a 50 and a 100 since one will run the splasher motor. 100's are the equivalent to two 50's so hence being almost twice the price. As for what size you need, 24v TM's actually draw more amps then the 36v. If your the type to fish all day or do tournaments then definitely go with 100's. For a casual user only going out a few hours at a time the 50's will be fine. 2x LiFePO4 50Ah batteries would be plenty for the average or above average fishing day. Running two 100Ah LiFePo4 batteries is essentially the same power as running -four- lead acid batteries. This covers some topics for comparing brands, they can vary from mild to wild. I have some budget and some high end (MillerTech) batteries.

I run 3 60ah with my Fortrex 112. You shouldn't have a problem with 50ah... Just put them on the charger after fishing and you should be good to go the next time out... Dan

I am thinking of converting my trolling motor battery overt lithium. I have A 24 VOLT MinnKota with spot lock etc.
I have heard that I only need a 50AH 24 volt battery? But I am concerned that is not enough and should get a 100 AH?
Any help appreciated.
A standard 12v Lead Acid battery is about 100Ah, but it's 50% efficient. For 2 lead acids you have 100Ah of effective capacity and it degrades with cycles pretty quickly. Lithium is about 98% efficient. So you'll have a 24v battery with 50Ah, which is the same wattage as 100Ah at 12v. If that made any sense, you'll have the same capacity as your two lead acids but much longer cycle life. lithium also put out 12v till they are dead, flooded cell will drop voltage as they discharge so you get a lot less usage from them compared to lithium.

FWIW I run a 24 volt Riptide Fortrex on my very light 18’ skiff. I have two 12 volt 100ah lithiums and the few times I’ve used it (I’m mostly on the push pole; rarely even take the TM), I have yet to run them below 75%. I’m wishing I’d gone with the 60ah batteries. The research I’ve done tends to bear that out. And that’s fighting coastal wind and tides.

I went with 2 12v 100ah. I run it 6-8 hours in the summer puling my boat against the Tennessee River current dragging planer boards.
