Unfortunately there are a log of blogs out there linking to a lot of products that claim to double your DS4's battery life. These are unfortunately all BS.
They are just mis labeled and falsely sold DS3 batteries, which are usually only 800mAh which is even less than the DS4 OEM battery which is 1000mAh.
The only way to guarantee a longer battery life on your controller is to get a rock solid no BS battery from a battery website or hobby site. In the video below I outline what I believe is the best pack that you are going to find out there that fits with minimal modifications and improves your battery life.
I develope the DS4Windows tool, currently we have integration with TheGamesDB.net API to retreive and display info about currently playing games in order to orginize user created controller profiles that can be uploaded. The issue is that TheGamesDB.net suffers CONSTANT outtages. I have set the application up with as much caching as I can to cut down on queries, but is GiantBomb capable of handling the sudden additional tens of thousands of queries a day?
@laika: That worked fine, and to clarify I have also tried from home, work and the bar, each with different ISPs aswell. Also co workers are able to connect fine which is why I tend to think its somthing with my account, though I can't figure what that could be.
