The 18650 Battery Shield V8 Power Supply Module is an easy and practical way to power your electronics projects from a single 18650 Li-ion battery. It works like a mini power-bank board: install a battery, charge it through Micro USB, and get a regulated 5V output through the onboard USB port and output pins. This makes it perfect for portable builds such as Arduino/ESP32 sensor nodes, WiFi projects, robotics, IoT prototypes, LED projects, and DIY gadgets.
With a built-in on/off switch, you can quickly control power without unplugging cables—ideal for testing and field use. The board also provides convenient output pads/pins labeled for 5V and GND, making wiring clean and fast.
This board commonly includes:
Note: Exact pin labels and output options can vary slightly by manufacturer batch, but the core function remains: charge 18650 + boost to 5V output.
