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.

If your Eneloops are failing that much, they are either being over discharged or something is wrong with your charger.

All of my Eneloops have been much more reliable than lithium ion batteries.

    I may be the unluckiest person in the world, but I've bought expensive official Eneloops multiple times and used multiple chargers and just gave up. Sure, it may be because I'm doing something wrong, but I certainly couldn't figure out what that may be.
