Xbox One Controller Custom Battery case

Description

Xbox One Battery Mod. I got tired of constantly changing batteries on my controller so I designed an alternative that uses items on hand (widely available) to replace 2x AA batteries. I got lots of spare Li-ion batteries from Disposable Vape Sticks and after testing the batteries, I used a matching pair to create a 2x AA alternative. Using two 13400 Li-Ion batteries (550mAh) and one USB-C ultra small battery charger/protection module I designed a case to the same size as two AA batteries. This is just first version, and the case is held closed by the controller battery pins. When discharged, just take out the battery, open the lid and charge them. Disclaimer: Never use untested batteries in series or parallel! Do it at your own risk! Take extra precautions on wiring to not short the battery. I am not responsible of any potential damage. You need at leas medium soldering and Electronics Knowledge (I will post no schematics here) Link for USB battery charger model: https://www.aliexpress.com/item/1005005037876729.html Note: I hate the idea of disposable vapes! In my opinion they are the most awful product ever created from polluting point of view, on the same level as chinese keychain toys that had living turtles or fish in them. Disgusting! So I try to recycle these batteries as much as I can(worst case, I just dismantle the thing and dispose the battery properly).
