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.

This is great, so far I have only seen hardwired options, never seen someone do a expanded battery mod for their smart lock.

Battery eliminators are the way I hardwired my smart locks. You can find these on amazon in various battery sizes and combinations. Combining this with a Voltmeter Adjustable Boost Modul, doing some wiring, and then plugging all this into the wall means no battery changes every 3-4 months.

Here's a video of something similar to my setup.
