Hi... I was hoping somebody could help me out. I am thinking of purchasing Marine lithium batteries for my trolling motor and wanted to see anybody's opinion the best budget 12 volt 100ah battery. I would need three 12 volt 100ah hour batteries for my 36 volt Minn Kota ultrex application. I saw on some of the videos the sok lithium battery (12v 100ah)but I wasn't sure if that was for a marine application . Please let me know your thoughts and any helpful advice. Thank you in advance!!
