Link to file for anyone else with same issue taken from another thread:
I donít know if you have a bedroom slide or not And if your battery house is close to your bedroom slide. Mine is so what I did is bought a dc-dc brick. I snaked the brick wire in thru the slide (close the slide enough to snake, then reopen). The brick is outside mounted under my slide to protect from weather. I then used the cigarette lighter to alligator clips to battery bank up thru vent hole in battery house.
From the sounds of things you already have the dc-dc brick which is what is recommended. Unless youíre going to bring that Ďextraí battery inside, you will still need some way to connect. This way might work for you.
I donít know what your cpap settings are and if you need the heat and humidity, I donít and as you can see from the resmed chart it will draw almost no current. Iíve used mine plus a residential fridge overnight many times with no issues. I have 2, 6 volt, golf cart batteries with 210 aH...
And, my DW would also make me sleep in the truck if my cpap did not work..lol.
