That is how you know the charge and discharge voltages.

I would suggest before doing any testing of these cells to study the? data sheet first.

If you do not understand the data sheet then don’t do this stuff.

Criteria: No fire, and no explosion. – WOW i’ve never seen any Lithium cell that can withstand that!
