Never Buy Batteries Again! How to Make a 9V Li-Ion Rechargeable Battery

This should get a ton of views and likes.

Normally yes it should, but KZbin doesn't favor this type of videos specially small channels like mine, beginning with 2017 is harder and harder to get views.

Thanks for the video, what a great project. Could you please provide the BOM?

[@GhoWriter]

where can i order two?

[@HMProjects]

You can't but I put all the files in the video description if you want to make it yourself.

Idle power draw? Low voltage cut-off?

[@HMProjects]

Idle power drow is around 1.5 mA, it's a little bit high but it is what it is, and the low voltage cut off is 2.5V, according to the datasheet of the TC4056 IC.

@@HMProjects First off: Great video, fantastic make! How do you protect the Li against deep discharge? The MT3608 has a lockout at 1.98V which will kill the Li if you forget to disconnect the cell via the switch. The lo V cutoff of the charger is 2.5V but that won't help with the steupup power draw... Or did I miss something here?
