The Gel battery I bought a couple of years ago wasn’t operating as well as I liked and the charger was almost constantly running. So I decided to upgrade to a 200AH LiFe Pro battery instead.
I bought it just before the COVID crisis, so it was reasonably priced with free shipping. I was also able to get some custom features so it fit in the space I had available. That meant that I needed a new charger and decided to buy a proper inverter special made for lithium batteries.
The previous charging system was connected to the front car battery as well, which wasn’t a good idea with the lithium setup because the batteries charge and operate at different voltages. The voltage drop across the conductor probably would have made it fine, but I decided to get a cheap battery charger from Harbor freight.
The two battery systems can be tied together via a switch beside the radio and a switch by the utilities, which switches between the new battery charger and the lithium batteries so that I can keep them charged while I am driving.
The area is a mess because every part of it was an experiment. I feel sorry for the person who follows me!
