My current deep cycle batteries for my 12v trolling motor have given up. Not complaining they are from 2019. Want to replace with the newer LifePo4 battery and looking for recommendations from folks that have actually had a year or more experience with these. What type ( brand), where did you buy, what charger, what qualities/ specs do I need to look for and any other information to help me make an informed decision !! 16' Sylvan side console, with MK 12v 55# trolling motor. Use the anchor mode the most, but also troll in early summer. Was getting 6-8 hrs trolling time from two group 31 batteries. Looks by for good bang for the buck and a company that stands behind their product if an issue arrises. Thanks in advance for any help..
