I have a BMV 702 connected to a battery system. I use the relay (normally energized, closed) to control another relay where all positive loads are connected. When the BMV detects the battery is below 11V the BMV relay is opened and the load relay is open, disconnecting all the loads.
The problem is that in this situation the monitor is consuming 15mA which is a lot. Is there any "clean" way to disconnect the BMV to avoid discharging the battery when the system is not in use? A switch in the positive supply cable? Any other way to achieve the same but but having the relay normally de-energized? Other solutions?
Thank you!
