Any one using these as starting or House batteries.
I have one for my trolling motor 36v but it charges not via the outboard 
My batteries are 11 years old and seem fine until they’re not
I want to at least swap out the current deep cell for a lifepo4 battery 
And my current onboard charger can charge this type of battery 
But my concern is charging while underway ..   seems to be 2 camps it’s fine or you’re going to blow up….  Anyone with real world experience on this topic
