Question:
I have a 2020 Buick Encore GX AWD, I am going to install a RVI Towed Car Battery Charger, the instructions say to disconnect the pos and neg battery terminals. My question is, can I do this with two Roadmaster battery disconnects? If so, can I wire both disconnects to the inside control switch?

Hey Darrell, thanks for reaching out!
The Roadmaster Battery Disconnect # RM-766 is only designed to be installed on the positive terminal (since the activation button pulls power from the positive terminal), so I recommend using the Roadmaster Battery Charge Line Kit # RM-156-25 as opposed to the RVi # RVI74FR for keeping your 2020 Buick Encore GX battery topped off.
You won't need the extra charging power of the RVi kit unless you are planning to have quite a few things pulling power from your Encore GX while flat towing.
If there anything else you're needing for your flat towing setup?
