Possible current draw issue?
I’ve had the BM2 attached to my EV6’s battery for over a year now, since I had the car towed in due to ICCU failure. It seemed to work well, but today while I was listening to the radio in the car while waiting for my wife at a hair appointment, I got a warning screen: “Battery low, come to a safe stop.” I checked the app, it said the voltage was down to 6.5 volts! So I got a guy to jump start me with his 12V battery cables, took my wife to lunch and then home, then onto my local dealer. The manager said they tested the battery, it was fine; the problem was the 3rd party voltage monitor. Its power draw, he said, could be enough to drain the battery dead. At 1.5mA, does that make any sense?
