“And by "storage," I mean "whenever I'm not actually on a camping trip, the batteries go onto the trickle charger."
LFP’s Uber low self-discharge rate makes the solution to this quandary easy…I simply added a battery ‘side’ post knife switch disconnect from Amazon which isolates the battery whenever camper is not in use…No need to keep on a trickle charger….In this way shore power (if available?) can continue to be used to operate the 12v systems via the onboard converter-charger…
I just don't plug in at home anymore and shut off my solar. no parasitic draws in my 32 yeear old camper... as long as I am under 90% I am happy for winter storage.
in the summer I turn the solar the morning before we are going camper so it is full when I leave and it can do its top ballance then I change the profile to run from 10% to 90%. I figure one top ballance for eaxh camping trip is enough.
when we upgrade I'll probably have to add somthing like that to my battery.
