I arrived at this thread looking for ways to integrate my portable battery pack (Ecoflow Delta 2 + extra battery) to my trailer (2019 23CB Int'l Sig) so that I can extend my
12V battery power during boondocking at cold nights to run the furnace (where my house battery for sure cannot last the whole night).
This thread has helped me to understand better about the possibilities.
However, instead of using the Ecoflow like shore power, I ended up using the
12V output on the Ecoflow and hooked up directly to the battery using the zamp solar input (SAE connector) next to the airstream battery box. With this, I was able to run the furnace the whole night.
I was hoping that when the furnace was used, it could draw more power from my portable battery pack. However, the highest output showing on my Ecoflow was only around 30 watt. So, it seem that the Ecoflow was only partially helping, and I would assume the house battery was probably run all the way down.
However, this was still a success for me. Now, I am looking for ways to connect the
12V output on my ecoflow to the battery from inside the trailer. How do I find the wire that connects directly to the house battery on the inside? Does anyone knows what should I be looking for?
