Tired of expensive disposable batteries and rechargeable AA suck. So I made a 10k mAh pack for my deadbolt. (sh.itjust.works)

Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.

Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.

This is a garage-door so its not critical access but is used a lot.

They did. With an electronic lock. And now many of us with similar needs are in an forum talking about how to make that experience better.

Meanwhile, you're spending effort being a dick to people over a topic you clearly don't have any stake in. You need to find a healthier hobby. It will make everyone happier.
