TP4056 18650 battery charger

I recently acquired a couple of notebook batteries, which I needed to charge and test promptly. To do this, I constructed a battery charger setup. To hold my batteries securely in place, I built a custom charger holder around my battery booklet: https://www.thingiverse.com/thing:4113164. This design allows me to easily attach the TP4056 charging module to the front of the holder and provides slots for the cables on the sides. Next, I arranged four battery holders side by side on an old ATX power supply, providing a convenient charging platform. Additionally, I placed two ZB2L3 modules adjacent to the chargers, allowing them to discharge the batteries while measuring their capacity.
