2 x 18650 Lithium Battery Shield V8 Mobile Power Expansion Board Module 5V/3A 3V/1A Micro USB for Arduino ESP32 ESP8266
The Lithium Battery Shield V8 is a versatile module designed to power devices like Arduino, ESP32, and ESP8266 with two 18650 batteries. It includes an integrated lithium battery protection IC that guards against overcurrent, overvoltage, and undervoltage, ensuring safe and reliable operation. The module provides two output voltages: 3V/1A and 5V/3A, catering to a range of power needs.
To use the module, make sure the positive and negative terminals are aligned correctly as indicated on the board. Incorrect battery installation can damage the module. The batteries should be within the typical voltage range of 3.2V to 4.2V. The 5V output is rated at 3A, with a maximum output of 3.6A; exceeding this limit may damage the module and reduce its lifespan. Please note that the actual output current may vary depending on the quality of the 18650 batteries used.
Features:
- Supports 3V 1A voltage outputs.
- Supports 5V 3A voltage outputs.
- Micro USB charging current is 600mA-800mA.
- Supports up to two 18650 batteries. It is recommended to use two 18650 batteries, which can be longer.

Frequently Asked Questions
What output connectors are available on this module?
The board provides a standard USB Type-A port for 5 V/3 A output and a 3-pin expansion header exposing 5 V, 3.3 V and GND for direct wiring to your development board.
What maximum current can I draw from each output?
You can draw up to 3 A from the 5 V USB output and up to 1 A from the 3.3 V pin header, making it suitable for most Arduino, ESP32 and ESP8266 applications.
How do I power an ESP8266 safely with this shield?
Connect the ESP8266 VCC to the 3.3 V pin on the expansion header, ensuring the current draw stays under 1 A. Ground the ESP8266 to the module’s GND pin to complete the circuit.
