12 volt fridges
Looking at a trailer with a 12 volt fridge and solar panel mounted on the roof. not sure of the size of panel. My question is this. how can i tell if the panel is charging the battery?

- How many "usable" amp-hours does your battery bank have (lead-acid batteries should only use 50% of the rated amp-hr and lithium should only use 80% of the rated amp-hr...using more can prematurely age the batteries). Convert to watt-hours by multiplying by 12.
Where is the reference about “only use Lithium to 80% rated amp hour” stated clearly by a battery maker? I’ve never seen it referenced except on this forum. I’ve read where a LiFePO4 retains 80% capacity after its expected recharge cycle life is exceeded. I’ve also read where you can fully discharge them and then fully recharge them with no damage.
