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.

Why not a cable for power? Does the door need to be able to go somewhere that doesn't have electricity?

May be an access issue. Enough distance and running a cable becomes a pain in the ass in a way that can make this more appealing. It's why I don't have an Ethernet cable in one room of my house; I'd have to climb either across the attic, or in the crawlspace, and neither are gonna happen voluntarily. So I deal with a crappy wifi dongle for the ancient PC in that room instead.
