So weight wise you're talking about saving approximately 25 pounds per battery with a 29 size? Is that about correct? I'm considering them, but have never had real issues with most lead acid batteries. I don't fish as much as I used to but still get out 50 - 60 days a year. Most of my lead acid's have lasted at least three years and some of them 4 or just a little longer. Trying to justify the price vs the weight advantage and for me (again, just for ME) I can't see it until lithium's get MUCH cheaper. It's a MUCH bigger weight difference than that. Typical lead acid cranking and deep cycle trolling motor group 29's weigh about 60# each or 240# for a 36V TM set up with a cranking battery. My Ionic 135Ah cranking battery weights about 25# then the 50Ah trolling motor batteries weigh about 6.5# each or roughly a combine total of 45# which is obviously about 200# less than the other set up. And for the question about cranking "issues". There aren't any as long as the one you buy has been programmed to support higher CCA's when starting the motor. I only know of 2 that have this set up today but I am FAR from an expert on these.

I wanted the lack of voltage drop and 5000 plus cycles.

Lithium’s are the best you can get if you are using trolling motor hard all day. I have 3 Dakota 100ah trolling motor batteries and with ghost and 520 ranger on set on 8 in the wind for 8 hrs it never lets up all day. Have a Ionic 4 bank charger and a Ionic 125ah cranking battery and even after 10 hrs it has never had to charge over 2 hrs. The weight difference did not change speed at all going from 4 group 31 agm batteries. Plus with with the Dakota it has 11yr warranty and I bought there golf cart pack and saved money. Would never go back to a lead battery.

I have been eying switching to lithium. The thing holding me back is the cranking battery ordeal. I don't want to have mixed batteries, either all agm or all lithium. No one answered my question so let me tie it back to the post I was addressing and reword it. Is there a problem with Lithium for troller and AGM for starting and accessories? Assuming charger can handle mixed profiles.

Can you get just one battery for a 36v set up , if so what do you recommend ? Thanks Yes, there are options. If you click some of the links provided there are some listed. Monster Marine https://www.monstermarinelithium.co...ing-battery-mml-3640-no-built-in-display- I think I saw somewhere where the Monster Marine rep said they would have a 36v/50Ah available soon too. Lithium Pro's offers a 36v single solution as well. https://www.lithiumpros.com/product/m3165-36ck-36v-65ah-trolling-battery-kit/As far as keeping your AGM for cranking and lithium for Trolling, yes you can do that. The only issue you will run up against is that you will need to have separate chargers, one for you AGM/one for your trolling motor batteries. The AGM will need to stay and cycle on the charger between uses but once the lithium's are charged you can remove from the charger and they can go for months before loosing a very small % of charge.

Im not a fan of one battery like that. I travel a lot if it had a issue I would be buying 3 to keep going. w 3 separate batteries if one has a issue I can buy just one and keep going. 50ah are small and are as low as 350 ea on amazon
