Building a High-Voltage DIY Power Bank using 18650 Rechargeable Batteries If you're looking to create a high-capacity power bank for your electronic devices, consider building one using 18650 lithium-ion cells. These rechargeable batteries are widely available and can be easily sourced online or at local electronics stores. To start, gather the necessary materials: * 12 x 18650 lithium-ion cells (available in various capacities) * A suitable battery pack enclosure * Wire and connectors for cell-to-cell connections * A charging circuit board (PCB) with a built-in voltage regulator * Power switch and LED indicators Next, prepare the individual cells by removing any protective plastic wrapping or tape. This will allow you to properly connect them in series. To assemble the battery pack, follow these steps: 1. Connect the cells in series using the provided wire and connectors. 2. Ensure that each cell is properly secured within its designated compartment. 3. Connect the power switch and LED indicators to the PCB. 4. Install the charging circuit board into the enclosure. Once complete, test your DIY power bank by charging it and then discharging it through a load such as a small LED light or a portable USB device.
