Hi everyone,
I have 18650 cells and i like to cut-off the cells at 3V.
I have 18650 circuit protection but they stop at 2.5V, it's too low for my boost modules who will be at the output.
I have build a LM358 circuit and tried with a led and works great. It uses a simple bc547 transistor.
Here is the shematic :
I'm finding a mosfet who can handle 5A or more max.
I ordered some MTP50P03HDLG mosfet for other stuff, maybe they might work.
The circuit might oscillate because the battery voltage will rise when the load is disconnected then the circuit will connect the load again so i don't know how to fix that.
I have some LM311 too if this coudn't be done with a LM358
Thanks
Regards
