Hello, I purchased a screwdriver with Li-ion battery.
I replaced the cells for efficient, high-current ones but the symptom is that the charger does not charge the battery and the screwdriver for a moment lights the diode and nothing more. When the button is pressed, the voltage on the battery drops to 0V as if the electronics cut off the current.
On the cells themselves, I currently have 3.6V on each, cells inr18650-25r.
And here is the question, how can I charge these cells one by one with a suitable charger from 18650, just a question whether I can completely remove this electronics and use without it on the basis of charging outside and working without internal. security, of course, taking care not to over-discharge the cells?
