Summary

Thanks to RaMarcus' channel (see link below), covering Oculus Go related stuff, I discovered that the Varta Powerpack 2600 is a nice add-on for the Go. Even though it's got the same capacity as the Go (2600mAh), it doesn't double the playtime. But it does add at least another hour (or maybe more) of VR experience. At least enough to kill a few more zombies :-)

The battery can be bought at Amazon for instance. Search for "Varta Powerpack 2600". They are available in a few colours, but the grey one matches the colour of the Go quite well.

The easiest way to attach it, is to loosen the headstrap a bit. Slide the strap in the holder and then slip the holder over the plastic arm.

The holder has a tight fit. So if your print has a large "elephant foot" you can use a deburring tool or sandpaper to make the battery fit. There is a lip underneath the holder (see rendered image) that puts some pressure on the battery to prevent it from sliding out.

If you have a different strap (like the Gear VR one) use the ClampNoStrap.STL. This one has a narrower clip and fits on the plastic arm.
