I suspect that your dashcams only turn on when the car is in ACC or READY(?); however, your OVMS is attached to the OBDII port and draws how much current?I had previously found that my bluetooth dongle IIRC drew about 60ma which, over 24 hours means 1.44Ah and if I were leave my car untouched over the course of five days that would pretty much flatten my 8Ah LiFePO4 battery. I have Anderson PowerPole connectors on every 12v battery and I'm in the habit of attaching a 12v power supply or float charger if a car is to sit for more than about four days.
