Ok, this might be a dumb question. I have a setup that I've been running for a couple of years and it works great. Battleborn battery wired as the "coach" battery in my van with a Victron 20amp MPPT. I have a port on the side of my van where I can connect foldable panels when I'm camping. It's great.
Sometimes I'm heading out in conditions where I know there won't be much sun. There is no space available to permanently wire in another battery, and a lot of times I don't need any extra capacity, but now that there are some less expensive LiFePO4 available, I'm interested in possibly bringing one along sometimes as a backup source.
I know there would be some efficiency loss, but I'm thinking the most convenient solution would be if I could use Anderson connectors or something alligator clipped to the "external" battery and just connect it to the input of my MPPT charge controller. Is something like this possible? Would I need to regulate the voltage going into the MPPT? Is there a better way to achieve something similar?
Thanks!
