The new Anker Docking system that you sell has a problem.
The Anker Docking system has a 1.2V battery in the controllers. The Oculus Quest 2 controllers need a 1.5V battery to track properly. I purchased one and charged it up and have been having tracking problems ever since. Today I figured out the battery situation from reading your materials and looking at the battery in the controllers.
I also have noticed that the controllers can get very warm after charging and the battery is almost too hot to the touch. These types of batteries when overcharged do have a tendency to start fires. But according to Anker, you should be able to leave the headset and controllers in the docking system all day/night and not have a heat problem.
I have put in a request to return my Anker charging/docking station but thought you and others should know about this problem.

I had the same problem with one of my controllers.... I noticed that the right docked controller LED wasn't turning green while the other two were. Decided to check it out. I removed the controller and tried docking it again and the orange light started flashing. Removed the battery on the right docked controller was HOT to the touch and smelled like it was melting.
I took the battery out and installed the regular battery to make sure everything was still working (thankfully nothing seems to be broken). Switched the batteries around and docked it. Now everything seems to be working fine as all three lights have turned green. But at the same time maybe it's not. There is definitely something wrong with the batteries though even if it is working properly now. I'm guessing it has something to do with the metal contacts and if it's not oriented in the "sweet" spot your mileage may vary.
