12V battery
Usually EV's have a 12V battery and a DC/DC converter to charge it from the main HV pack. I haven't seen any mention of this or seen it pointed out in a video walk through. Does anyone know where its located? My other Audis have the battery in the trunk but I've only seen the audio subwoofer in the back of the e-tron. It's possible this is a very small lead acid battery because it doesn't need the power to start an engine.

perhaps somebody can post a VIN number or one that is one digit off from one and we can then look at a manual. The previous posting of VIN numbers was from pre-production cars (I think they had XXX in the number) and thus a non-valid number to get the manual.

It doesn't have to be a lead-acid battery. The motorcycle aftermarket is now providing a LOT of Li-ion 12v. batteries that are quite compact and light. One of the good things about the EV/PHEV autos is that the onboard DC/DC charger keeps the 12v battery charged from the high voltage battery. My previous BMW and M-B ICE's that were mostly city driven had to be kept on a maintenance charger because in-city running would never fully charge the 12v lead-Acid battery.

The owner manual mention a 12V battery, and states that it is serviceable by dealer only.
