The BMV-712 "Remaining time" is not quick to calculate like my previous battery monitor. My 12v fridge turns on (drawing a constant current), and the "Remaining time" reading slooooowly decreases. Too slow. The fridge turns off before the reading gets anywhere near where it should be. My previous BMS took 2 seconds to re-calculate (once the current draw was constant). What gives?
Decrease the "time-to-go averaging period" if you want a more "responsive" number.
But just because it "slooooooowly" decreases it does necessarily means it is off. If you have a large battery, a fridge should not drain it just in a few minutes, so the "time to go" should not rapidly decrease.
