Black and Decker Li-ion charger

Charger designed to safely charge 3s2p 5Ah Li-ion battery pack in an old Ni-Cd battery case for a BnD powertool. In the battery pack I used 6 18650 2500mAh Li-ion Cells and a cheap 3s BMS from aliexpress. In the charger i used an LM2596 DC-DC step down module setted to 12,4V 1A. It takes a few hours to fully charge the 5Ah battery pack, but hopefully it will last much longer as the old one.
