Ihe display on my BMV started flashing. I read about others having similar problems and based on their experience I jiggled the red power wire going into the shunt and now the display works but the Amp reading is way off. When I power the electric hot water heater in my RV through a 3000 watt sine inverter the BMV 700 reads less than two amps discharge rate. Using another amp meter I can confirm the actual draw is over 130 Amps.
voltage is correct but Amps are way off. Just to make sure I left the electric hot water heater and refrigerator on long enough to drain my 3 Battleborn Lithium batteries. The voltage dropped to 11.7v and the cumulative AH’s on the BMV were around 13. Going to order another shunt. Hopefully that will resolve the issue.
