Finally I assembled everything.
So, first power on…only the main switch of the charging psu is on…the switch on the actual battery board is open…:
– three slow blinks …battery fault…means what ???
– when I switch the switch on the battery board on (it not a push button, but a normal toggle switch)…led starts to blink fast 9-10 times and than goes back to slow three times blinking.
So, before I now try to set the charging current etc…what does battery fault mean ? Is this expected behavior ? I dont have a load on the battery supply right now as I want first to see it giving me the right voltages before I connect it to anything.
