Hardware Programming | Battery Capacity Testing Robot [ Part 3 ] 

This machine will automate the capacity testing of 18650 cells based on a constant 1 amp current draw. I have a few hundred 18650 cells that were salvaged from laptop batteries. Some may be good, and some may be bad. I want to assemble all of the good batteries into packs for my camera, phone, solar power bank, the list just goes on really. This machine is the first step. Also yes the stack of batteries was a very dumb idea but I tried to use the parts I already had. Obviously a DC(high rpm) motor is not suitable especially since you cant really do precise movements.

Battery Discharge Protection Circuit: Designed by me last summer :) This circuit monitors the battery voltage and disconnects it from the load at around 2.52V. It needs an external signal such as a switch or an Arduino digital write to turn on the battery once it disconnects. When the battery dies, the circuit disconnects itself from the battery, drawing zero current in its off state.
