Helpful Expert Reply:

To charge your auxiliary battery on your enclosed trailer while you are towing you will need the Redarc In-Vehicle BCDC Battery Charger - 25 Amp # 331-BCDC1225D or 40 amp # 331-BCDC1240D.

The 25 amp is the most likely choice for you because it is for batteries (or battery banks) with 75 amp-hours to 200 amp-hours ratings, while the 40 amp charger is for 200 amp-hours and above. You will also need the 40-Amp MIDI Fuse Kit for Redarc In-Vehicle 25-Amp BCDC Battery Charger # 331-FK40.

So long as your battery (or batteries) are fully charged, you will be able to use them when not connected to your 7-way.

I have added links to installation videos as well as links to the installation instructions for you to check out.
