battery capacity for bluetooth OBDII
Hi guys, total newb with electric stuff... I would like to run the DashCommand app via Apple CarPlay or the AppRadio on a head unit, and I was wondering if running the car with the bluetooth or a wifi OBDII module always plugged in would drain the battery. I have a tiny Shorai with a short reserve hour, so anything that will drain the battery is a concern for me. Is there a way the OBDII scanner will turn on with ignition, or any other smart solution? thanks in advance.
