Use this to connect directly to the 12v battery as it will do an autoshut off based on time or voltage.Do not use service mode - do a real start -- car will auto shut off after ( x hrs ) - I did not get that software update for my 2012 Volt.
Easy to direct connect to the 12 volt battery

I’ve since sold most of my equipment as I drive 18 wheeler and didn’t have the time anymore.Nice to meet a fellow remote pilot here! I fly the DJI Phantom 4 Pro V2.0 with 4 batteries. Cheers!
