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 does a dead bolt need batteries? Also if it's just used form some sort of sensor and the door it used a lot, would that just be noise at that point?

Its the sensor is used for the alarm and to run automations based on if the door is left open. Like turning off the AC and sending me a notification if the door is ajar.
