Tired of expensive disposable batteries and rechargeable AA suck. So I made a 10k mAh pack for my deadbolt. (thelemmy.club)

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.

Only cheap ass locks use unprotected NFC/RFID. Like your debit card also uses NFC. Can you clone a debit card or make a payment with a spoofer app? no you can’t. Just because it’s NFC doesn’t mean you can just spoof it with a Flipper Zero. If the NFC is protected with cryptographic authentication than that is impossible.
