DIY Fast Charge 130W Power Bank

I build the power bank by assembling a 5s Li-ion battery, hooking it up to a BMS, and adding a few more modules to make it all work. The Power Bank has 3 USB Type-C ports for charging and I added an OLED Display which shows detailed information about the battery inside. You can check the voltage of each cell, the total battery voltage, and the battery charge percentage.

In this video, I'll show you how to build yourself a fast and high-capacity power bank at home! You can use some old 18650 cells, pair them with a few more components, print a case, and assemble it all together!
