I see that most guys are running 3 100AH lithium batteries. I have a 112 Ultrex and I fish a lot of current. If I am in search mode prefishing a lake, especially during the spawn I can drain my 3 Deka 31 AGM's in 6-9 hours. My question is are 3 100 AH lithiums overkill? I don't mind charging every night. Would 3 50AH batteries be sufficient? I prefish daylight to dark sometimes 3-4 days in a row. I may stand on the trolling motor on 100% for a large portion of the day. There is a big price difference between 100AH and 50AH batteries. Will 3 50AH lithiums last all day at 100% and has anyone tested them to this degree?
