Description
the PBC2 Power Bank Housing with PCB is a practical DIY solution for making your own rechargeable power bank using 18650 lithium-ion battery cells. The housing provides space for up to five 18650 cells, allowing you to build a power bank with the capacity you need.
It comes with an integrated PCB that manages the charging and output functions and includes protection against overcharging, over-discharging, over-voltage, over-current, and short circuits. A digital LCD display helps you monitor the power bank’s status, while the four LED indicators provide a quick visual indication of the remaining battery level.
For added convenience, the housing includes three USB output ports for charging compatible smartphones and other USB-powered devices. It also features a high-intensity LED flashlight, making the unit useful as an emergency light or portable torch.
The PBC2 is a good choice for DIY electronics projects, repairs, custom power banks, and users who want to build a power bank using genuine 18650 cells instead of relying on pre-built units with uncertain battery capacity.

Important Note
18650 battery cells are not included with the housing. You will need compatible 3.7V 18650 rechargeable lithium-ion cells separately.
The five cells must be connected in parallel so that the battery pack remains at approximately 3.7V nominal. Connect the positive terminals together and the negative terminals together before connecting the battery pack to the PCB. Use compatible cells and follow proper lithium-ion battery handling and wiring practices.
