I have a 65amp "dumb" Battery Protect. I have connected a relay to it to disconnect my inverter on low-voltage. The BP doesn't actually disconnect though. During under-voltage there is a roughly 2-2.5v on the output terminal. This is enough to cycle my relay on and off. If this thing is marketed at disconnecting the load, why doesn't it actually disconnect? Why is this 2.5v and not ZERO? What can I do here to make this work like something that will actually protect my battery?
