August rechargeable batteries

I have an August Smart Lock and they require Lithium 123 batteries which are expensive and don’t last as long.

I’ve noticed that disposable vapes use a very similar 4.2v Rechargeable Li-Ion battery which is almost the same size.

So I’ve created my own rechargeable battery from 2 cells I rescued from 2 used vapes.

Adding nickel plates to the edges does the trick.

You can charge them with any Li-Ion battery charger such as this one which can also charge a bunch of other types of batteries. Or you can go very simple with these cheap chargers.

Built with:

• Rescued 4.2 batteries
• HAKKO FX-888D Soldering Iron
• Nickel metal strips
• XTAR VC8
