Cool. It's true that your furnace may be damaged from low voltage or dead batteries while boondocking due to the high current draw of your blower motor. The solution is to get rid of your outdated lead acid batteries and replace them with LiFePo-4 batteries. LiFePo-4 batteries are lighter, more energy dense, and the voltage doesn't drop appreciably till they are about 90% discharged, unlike lead acid batteries. In fact, a lead acid battery that is discharged to 50% (which is its practical limit) is down to 12v, whereas a LiFePo-4 doesn't drop to 12v till it's discharged 90%. Not long ago switching to lithium batteries was a very expensive proposition, but not anymore, especially if you assemble them yourself like we did. We live FT in our coach, boondocking most of the time. We replaced the 2, 6v FLA GC-2 golf cart batteries that came with our coach with a 12v 560ah LiFePo-4 battery that we built ourselves from 8, 280ah prismatic cells. We use a Heltec 330amp (1,200a surge) BMS with a 5a active balancer to keep it safe and happy. Properly cared for this battery will outlive us. These cells fit perfectly under the steps of our MH where our old pair of golf cart batteries used to reside. Not only do they have over 5 times the usable capacity of our old lead acid batteries, but they save us 30 lbs. too. We keep it charged with a 620w liftable solar array mounted on the side of our MH, which doubles as a nice awning for our bedroom window too. Take care, Chip
Good thanks that means i need a dedicated batteries or battery for the furnace with an BMS for that battery{s} therefore leaving me with a new total so far at three systems. Engine,house,and house furnace. Ill add that immediately.
Yes you can. It would not be hard to set up. If you use Victron I believe the Cerbo can be programmed to start the generator when your batteries drop to a certain voltage. Thanks for watching and commenting.
I just thawed out my holding tank by backing trailer in a large garage,,,,, and put ceramic space heater next to frozen plastic tank 4hrs off over night in garage,,,, then 2 more hrs w heater and got almost all the water out of the system. I even tilted the fresh water tank up high to really empty things out,,,,, A success indeed.If I knew the seller was filling it up in October I would've told him PLEASE DONT FILL MINE UP
Absolutely, that’s one of the many reasons we use lithium. But when it hits near 0 the BMS will Shut the battery off and the furnace fan will stop suddenly. Thanks for watching and commenting!!
Thank you. As someone who this is all foreign to, this was very helpful!!
Thanks. Glad I could help and happy for the view and comments.
Very helpful information.
Thanks!! I appreciate the view
And comment.
Good simple explanation! Good job. My camper heater is over 25 years old, so they can last a long time.
Cheers,
Kevin
Thanks, Kevin. It's amazing how long RV equipment can last!
Thank you! Very Informative!!!!!
Thanks for watching!
Great video
Thanks!!!

Good information and I appreciate you sharing your lithium battery setup! It's impressive and a great set up for anyone getting off grid.
I thought those batteries went dead too overtime.
@@philhacker2405 Please explain.

Best to just relocate to warmer weather. That’s why these things are mobile.
That’s one way to do it.
OK...did you take yours out or just carry one around just in case. Haha Good Video.
Doesn’t everyone carry around a furnace? lol. Thanks
Coming up on 9 years living in mine. Haven't used the furnace for 6 years. I use a wood stove.
I love a good wood burning stove. I had a small cabin years ago and enjoyed feeding the stove and warming up next to it.
Can you have a genny backup that could switch on should your battery drop below the proper parameters?
Yes you can. It would not be hard to set up. If you use Victron I believe the Cerbo can be programmed to start the generator when your batteries drop to a certain voltage.

If that furnace goes out and your pipes freeze it will be a bad day.
It would be indeed.
Way to state the obvious

I always carry sail switches. They are cheap!
Agree!! Thanks for watching.
300 ah of lithium , you can draw down to zero

I just use the electric fireplace. Saves propane.
That works until below freezing. Then you need furnace to protect pipes and tanks under the RV.
