I am looking for a battery for the MangOH yellow but couldn’t find many references. After some digging I saw one on Amazon that looks like it might fit, I will check the polarity etc. (it is a replacement battery for v1 PS4 DualShock controller https://www.amazon.co.uk/gp/product/B07ZC1YW6X).
Does anyone have any tips for battery use or how to ensure long life?
In case anyone was thinking about the battery I linked - the connector is a perfect fit but the polarity is reversed. I popped the wires out of the connector and replaced in the correct polarity, based on the images in the user guide pdf. It works after my change.
