E-Torque 48V lithium ion Battery ???

[DUNE RAP]

My question is if your Wrangler is equipped with the E-Torque system the Jeep has a 48V battery pack on board. For camping situations would I be able to run for example a “heating blanket” off The 12V battery for longer then someone with the same Jeep who doesn’t have E-Torque? From what I can tell the 12 V battery is backed up by the 48V lithium ion battery. The question would be is the lithium ion battery connected while the vehicle is not running. Anyone have any information on this?

2.0 turbo e-torque here: pretty sure they aren't connected, other than while running or during a start/stop event where it helps charge the cranking battery. It doesn't help regular cranking or accessories. Someone here knows the details.

There's also a person on here that wired his jeep to utilize the e-torque battery, you can Search the forum; I'm pretty sure he did a write-up on it, but it involves smarts and wiring, so I gave up on it for until I have a better handle on both. I think he converted to 24V, like the rest of the world.

Heated blankets take 60 watts or something, so maybe an external battery would be easier. 500 amp hour lithium-ion batteries are popular now, and LiFePO ones are getting started. 500 amp hours should last most of the night, you just get a free alarm clock un the morning.

I might be biased, as I was taught to fear the old heated blankets as a fire hazard when I was a kid, and am self-taught to be afraid of lithium ion, but I'd use a hot water bottle or hand warmer at the bottom of a sleeping bag/down quilt before them in the jeep. Wait, I already do.

Thank you so much! I camp out of my Jeep about seven times a year. Just looking for alternatives...

Not at all. I always have a synthetic quilt and wool blanket in my jeep. You can stuff them over the roll bar, takes zero space.

If you have a campfire or something, just heat up some water at the end of the night, put it in a big bottle, then wrap it in a towel and stick it by your feet when you sleep.

You can also rig the tailgate so that you can open it from the inside, it is super great when sleeping in the back with the seats down.
