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.

I can head out for a walk without bringing my keys with me. Kids can open the door while I’m grabbing the groceries or other stuff. Can provide a temporary code for someone to check on it while I’m out. Family can have a code for emergencies, or if they need to watch the kids.

It’s hella convenient actually.
