Based on my BMS my AGM 390 Ah battery is about 61% full. My DC to DC charger pushed 30 amps to it so that seems legit. But this 15 A AC to DC charger connected directly to the battery (not the shunt) can’t get above 12.7V | 0.8A when I plug it in. And then it’s clicking. AI tells me it’s the internal relay doing this but I can’t get much more coherent from it.
What is the deal with that? It’s updated to the latest firmware. When I reset to default settings this doesn’t change and changing the voltage to high (14.7 V) nothing changes either. Am I misunderstanding how this thing works?
