Trolling motor battery question

I have ionic lithium and love them. 
1850 crestliner full windshield 4 guys in boat  Running front at 4 -5 for about 20hrs on Erie. Still have about 30% left. I do use a kicker. 
31 series lead, I would get about 8 hrs. 

?Battle Born 2-day sale???

Look at Weize lithium batteries. Good prices and very good warranty. 

Migr8r - talked with a minnkota rep and he said you are fine with lithium batteries running trolling motors if you don't run 85% or higher power for extended periods of time. He said if you stay under 8.5 setting (85%) on your remote you won't draw enough voltage to do any damage. I don't know what their view of extended hours is in real time, but still good info to protect your motor.

Migr8r, thanks for the info! Battleborn lithium 100ah is one of the batteries I researched and found great reviews, sounds like the direction I'm going to go. As for damaging my 10 year old TM, the spot lock is already broken/not working, so I'm probably going to be getting a new Terrova 80 sometime soon. So, this is the perfect time for me to push the lithium batteries hard and see how much the TM can handle. If I wreck it, time for a new one...

I have a 24v terrova as well and ran 2 AGM batteries for years. Last year they both died. It was a tough pill to swallow but I got 2- 100ah Battle Born batteries and glad I did. I’ve trolled with them for full days at 2+ mph and haven’t run out of juice. In my opinion, if you fish weekly and have a need for them, I’d definitely go with lithium. If you fish a couple times a month or less, I’d go with agm at a reasonable price (not optima). I haven't experienced it but the one thing I have been cautioned about is that there is potential for a TM to burn out from extended use with lithium’s. Knowing that there is potential of burning out my TM, I try not to push it by running at full power for more than a few hours at a time. I also got a 75ah lithium for my electronics to keep them separate from my starting and trolling batteries. If I could do it again, I would have bought 3- 100ah batteries and rotated them every year.
