battery In this video, I will show you how to make a 15000mAh Power Bank by using 18650 batteries salvaged from old laptop battery. I have also made the enclosure by using my 3D printer. 👉 Project Documentation : https://www.opengreenenergy.com/diy-18650-power-bank/ 👉 Download 3D printed files : https://www.thingiverse.com/thing:4890270 👉 Features: ★ Dual output current: 5V 2.4A; ★ Input voltage : 3.0 - 4.2V. ★  Protection: overcharge protection, over-discharge protection, short circuit protection, constant current. ★ Charging cable: support three USB data cable charging, including iPhone and Android.
