This board sometimes no power. If I reconect the battery it works again 1,2 days and then no power again. I need to reconect battery each time. Any idea?
Battery charge, discharge correctly. Can see the %
PPBUS with battery 8.42V

Cases like these are pretty hopeless. Corrosion under SMC would be a good start, also inspect the rest for corrosion.
