How to Make the Ultimate 18650 Power Bank with Infinitely Expandable Capacity

In this video I will show you the ultimate solution to power on the go. This DIY power bank features a removable battery pack, which can be easily replaced, giving this power bank unlimited capacity as long as you have enough cells. The cost of the row components of this power bank is around 60 dollars, which is two times cheaper than anything commercially equivalent. WARNING: Do everything at your own risk, lithium batteries can catch fire or explode if mishandled. This power bank requires a more than a basic understanding of electronic to complete. Schematics and the script: 3D print and CAD files: If you need a 3D printer, here is a really good one for only $220(Ender 3): If you like to see behind the scenes stuff support my channel, get frequent project updates, or chat with me, please consider joining my Patreon: https://www
