Aim is good & worthy but your constant fiddling with equipment make it unwatchable, why don’t you add a current variation device to show neatly, how the goal can be achieved !
Forgive me this time ,next time i will do my level best , and about the 'charging current variation ' tp 4056 is adjusting its charging current through its programming resister.
Idea is nice, but modules used for charging & you changing output voltage while the battery is connected - dude thats highly unsafe ! Potential fire hazard - Stay safe - Stay Alive
Charging any Li-ion, Li-polymer, Li-FePO4 cell with that circuitry is dangerous, the way you do it in this video. For these batteries, you're supposed to set the voltage control of the buck regulator to the maximum voltage for the cell on charge, before connecting the cell to the charger. If you change the voltage control when the battery is connected, you can accidentally set it too high. At the end, your cell will be damaged and might even explode. You're relying on the maximum current limit of the buck regulator. It can be used to charge large cells that can take 3A. For anything smaller, use a regulator that also has current control.
i will appreciate you about the argument of safety concerns . if you want to charge battery safely ,then you need to provide the exact charging voltage ,for example 3.7 v battery need 4.2 volt ,3.2 v lfpo battery need 3.7 volt for charging ,internal resistance is low when the battery is fully drained , at that time charging current is high ,but it doesn't mean it crossing the limit ,today battery's are support fast charging like 0.5C to 20C .3.2 v 6000mah battery support 1C continues charging that means 6A charging current , li-polymer is also support fast charging up to 3C . i am using this unit for charging different battery's , at this time i didn't face such a tragical situation, but still safety is important . please provide the correct charging voltage provided by the battery manufacturer . thank you
