I have the BMV-700 installed in a solar powered camper van with AGM batteries. My understanding is that I can set the BMV relay to disconnect power so that I do not overdraw the batteries. I have set the floor parameters in the settings and done some tests. I set the SOC% floor and also the battery voltage floor and ran a bunch of power through to draw the batteries down. The BMV shows that the battery percentage and voltage are both lower than the floor that I set but it did not alert or use the relay to shut power down. I drew it all the way down to 11.4V and it read that as 35% remaining. That was as much as I felt comfortable draining them.
What am I doing wrong? Or am I misunderstanding the capabilities of this unit?
