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

Never Buy Batteries Again! How to Make a 9V Li-Ion Rechargeable Battery
In this video I will show you how to make this USB 9V Li-Ion ( LiPo ) rechargeable battery with a 3D printed case, I also designed PCB for this battery that contains the TC4056 battery charging IC that it will ensure that the battery is properly charged and the MT3608 boost converter to boost the battery voltage to 9V.

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?
