Can you plug into 15amp even without battery in your rv

Anyone pull out the battery tape battery ends and plug their RV into the house? My battery is out and battery box sealed but I need to work inside mine so need heat and electric?

Some rigs you can, but many run 12v systems through the battery.. not directly from the converter. No harm in giving it a try. Worst case, just run an extension cord in through the front door and plug in an electric heater.

I (unintentionally) had the trailer plugged in with the battery disconnect switch open, so kind of the same thing as not having the battery installed. Everything worked, and the converter supplied 12 volts to the lights and other 12V stuff.

The way I realized it was the slide motors were cutting out. The battery gives you a "buffer" for surges or higher draws. Once I closed the switch, the slides ran smooth again.

So, yes, you can plug in without the battery - not sure if there is any risk to doing it.

Somethings will work and some won't such as landing gear. Lights should be okay but not anything else.

My landing gear, both slides have in-line fuses directly off the battery, so I presume they will not work, as is.

We are at an Arizona RV Park and have not had batterries in our 5th wheel for years. We do not move it and power is reliable. Everything works great, except the fridge will not switch to propane if power goes out
