Parallax 7355 replacement
I have a 2012 FC 23FB w/dealer installed solar in 2016. The original batteries are worthless (to be expected, they're old). I grabbed 2x LifePo4 batteries on amazon for $800, although I'm on the fence with returning them vs. making all the necessary mods to support them. I can only fit one in the battery box, so I'm looking at my options. I know I need to swap out the converter/charger, currently a Parallax 7355, to something that will properly support the lithium batteries. There are a number of options I'm finding, some a complete swap of the whole box, some a replacement of just the board. I know I definitely want to keep the same size/location. Before I pull the trigger, any suggestions?
