I am winter-exploring my so-far-not-used-by-me Riv and I am a little mystified:
Back in the aft cabin, beside the battery box, is a NOCO Genius Gen2 Mini 2 bank charger that I plug in for an overnight every once in a while as the boat sits wrapped in my yard awaiting spring. So far so good.
Now I dig around under the forward lounge where I find a Guest 2610 10 amp 2-output charger, no idea what it is charging and how it is doing it from so far away from the batteries.
Any ideas or clarifications welcome.

And while I have your attention, and maybe off-topic but maybe on topic, depending on the answer:
I also found the very odd little metal push-button alongside the very odd input/output thingy located at the stbd passenger seat, pictures below.
I need to know what these are for!! The manual as usual is not helpful. Ideas?

And Happy New Year Carverites!
