Powerbank DIY 12000-16000 mAh 2.1A

Summary I made a powerbank for 18650 batteries, 4 of them. Please enjoy, there is a youtube video for the assambley (PART 2). There are three different lids for it, if you wish to replace it after a while of use. Its 2.1A USB pcb-board so you can charge an ipad without problems. You can buy the parts for the powerbank here:
