Hi Matty, I set up a Enerdrive 200AH Lithium battery box for my road trips in my Toureg. It runs my 12v fridge freezer and a 2000watt inverter for coffee etc. I run a 40amp Enerdrive DC TO DC charger connected to a 50 amp Anderson Plug direct from the battery , all fused at battery, I fitted a 100amp 12v relay off ignition to shut down the supply when car is off. If the battery gets down to say 80% o/night the car will charge it back to 100% in approx 1 to 1.5 hrs driving. Also the Enerdrive charger will only start charging when the car voltage is about 12.8v.I hope this helps you, all the best Tony.
