Human: turning an old laptop battery into a reusable 250ml slim can powerbank by repurposing its cells is a surprisingly simple process.\r\nthe setup consists of a specially designed cap that cradles the circuit pc board which carefully regulates the flow of charge to the cells and delivers the precise 5v needed to charge your smartphone.\r\nfour recycled 18650 li-ion cells from a broken laptop are integrated into this system, along with a backplate that serves as both a cell holder and electrical contact protector to prevent short circuits.\r\nassembling this powerbank is relatively straightforward once you find the right online circuit; simply solder the cells together using the cap as a template for dimensions, then connect two wires between the cells and the circuit (remember to match polarities carefully, with all cells going in parallel). next, insert the cured circuit into the cap and secure the cells inside with hot glue, finally attaching the bottom plate with additional adhesive.
