Are you discharging the battery at a constant current rate? Is there any option to control the amount of discharge?
Also what controller you are using for USB bar code scanner?

@cookiecookie12 it is just two different mounting options
cookiecookie12
what type 3.3 ohm 10watt resistor did you use and why are there two different ones in the BOM
brettwatty
@marcingebus the two Mosfets are for THT or SMD options.

hello. do you have a gerber file for this Arduino 8x 18650 Smart Charger / Discharger
Marcin Gębuś
At night I dreamed about the charging project with the help of TP4056, 18650. And unloading with the measurement of capacity. The whole is controlled with the help of Arduino. Before I discovered yours. I like your project very much.
I have a question:
For what purpose do you use IRLML2502TRPBF and IRLZ44N in parallel? What is the purpose of the automatic disconnection of the negative battery terminal from the mass (Q6+Q30 for example)?
