My 4 Battleborn Lithium batteries were in storage and disconnected for the past 3 months. I connected them today and turned on my Victron Multiplus. However I am having issues with the DC Voltage. When I read the voltage directly on each battery as well as the bank itself, they all register 12.8V. However the BMV 700 is reporting 14.3V and I am getting a High Voltage intermittently. When I attempt to turn on my furnace on my travel trailer, I then get a Low Voltage alarm and the furnace cannot draw enough 12volt power and shuts down. The Multiplus shows absorption mode and does not appear to be charging. What would cause the BMV to report the incorrect voltage, and how can I correct this?
