Adapter pin sạc dự phòng cho dây đeo Quest 2

I am not sure how useful this is as it only works with the specific strap I have. If you are interested in buying the same one, here is the link:

And the battery compartment is also tailor to my own, which is this one:

I am very new to this hobby, so the model does not look that nice. However, it does survived a few beat sabre EX+ session, so it definitely works. if you have the same strap, but different battery pack, feel free to remix it. I think the battery compartment is big enough. If you are willing to use some 3M double side tap, you will can make most of the compact battery pack work. 

Update:

I did some improvement over the original model. 

• made the battery compartment round so it is does not have shape edges
• made the connecting interface opposite in slop so it can lock in better
• update the cap to have fit the case
• add cable management
