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.

Which lock are you using?

Been looking at Schlage for a nice local only Zwave / ZigBee lock but I've seen a few recent reviews saying how their quality went down the drain. How the PCB is corroding from just moisture in the air... So I'm open to recommendations.

You can the model in one image I posted. Its a Ultraloc, I dont recommend but it is better than my old schlage since when those batteries died you are screwed but these have a backup external power plug.
