Question - if E Torque battery dead will Jeep still start?

[Crowbar]

Just a hypothetical question regarding E Torque: if the E Torque battery is dead, the 48v battery, will the Jeep still be able to start? Just asking to learn about the e-torque system since I have a JLUR with a 3.6 with e-torque on order.

Theoretically, but being that all accessories and loads are run off the 12V battery, which is charged by the 48V battery and it's charging system, I can't envision a scenario where the 12V battery wouldn't die 1st? When our 2019 2.0t with etorque had charging issues, it was the 12V system that would dip in voltage until it got so low the Jeep wouldn't run. On the bright side, letting it sit shut off always allowed the 48v DC to 12v DC converter to catch up and the Jeep was back to normal. If your 48V battery died you'd be SOL real quick.
