I use the same set up on my new BT50, it works fine. I monitor the system voltage and it runs around 13.8 to 14.4. I have heard that the BT50 doesn't have the same smart system as the Ford Ranger (They are the same vehicle with some minor changes).

I mounted my Redarc next to the vehicle battery.

Some time around early 2013 the BT50 changed to ECU control of the alternator I believe. I also believe it may be possible for dealer to turn off the smart charge function.

Talk to your dealer if you have a model from 2013 0n.

Mine is a late 2013 model. I did ask them to fit the Anderson plug before delivery so they may have made the intellectual leap and disabled the ECU Control.
