Apple has made some strange decisions with the battery. It's external, and it doesn't look like can hot-swap. They don't have a double or triple capacity battery for more runtime. It doesn't have MagSafe. No one knows what connection design it has going into the headset.
This design means they can control the connection point to the device so that 3rd parties don't have heavy or odd colored cables hanging from it and the cable doesn't get in the way.
The battery pack has a USB-C port on it so USB-C battery packs can be plugged into it for more runtime. It can also be wired to a socket but this could risk overheating.
The recommended way would be to buy an extra battery:
Keep one battery on charge, then swap them over. The headset might power down but I could see them having an internal power system that can keep the RAM state for a while.
Most people won't want to use the headset for over 2 hours without a break but plugging in a power bank can give all day battery life:
I'm basically thinking the battery design is perfunctory right now, targeted for 2 hours, and they are waiting on how people end up using it. They will adjust then.
For hot swapping, it's not going to be great if the system has to reboot. If it is like sleep/standby and wakeup, it would be better. So, wait and see.
The device is advertised to be home or office mobile. Having the battery plugged in sounds dangerous as people will forget to unplug when they walk away.

Btw, the connection from the audio pod straps probably is USB3/4 or Thunderbolt protocol with 12 wires inside. Maybe 9 wires for USB3. Tough to tell, but it is definitely thicker than Apple's typical charging cables for iPhones and iPads. The cable is pretty thick to be USB2. During the WWDC state of the union, it showed images of a VP with a USBC dongle on the right audio pod strap. So, there is a barrel style, or pogo pin connector, with 12 pins? Complicated.
Anyways, if it is USB4/TB protocol, a user could plug into a PC or Mac and have enough bandwidth for multiple virtual displays, which could be interesting.
