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.
