Question:
I am working on adding power to my ATC enclosed trailer, and my goal is to utilize a solar panel with lithium battery setup to run a few small items. My question is if I want to also add the ability to have the tow vehicle charge the battery and connect it through the 7-way plug, which isolator would be best? Or is there something else needed? Obviously I want to be sure I don’t drain the tow vehicle battery

Expert Reply:
Your best option for charging the battery bank on your enclosed trailer from your vehicle battery is to use an in-vehicle, BCDC battery charger. The correct option depends on the size of your battery bank.
- Redarc In-Vehicle BCDC Battery Charger # RED96FR (Ideal for smaller battery banks rated less than 75 amp-hours)
- Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D (Ideal for battery banks rated between 75 and 200 amp-hours)
- Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1250D (Ideal for battery banks rated greater than 200 amp-hours)
All of these options have a battery isolator function that prevents the charger from pulling power from the start battery when your vehicle is off.
