I have been exploring changing out my lead acid trolling motor batteries on a 36 volt system to lithium. One manufacturers rep recommended a single 36 volt 100 AH battery versus three 12 volt batteries. Is anyone running a single 36 volt battery on their rig and how do you like the performance? I know the possible downside is if you have an issue, I would have a large battery to repair or replace. The convenience of a single battery does appeal to me. Let me know your thoughts.
