Purecrea 2x18650 Lithium Battery Shield 5V 3A / 3V 1A

This battery module is perfect for powering your Raspberry Pi, Arduino, ESP8266, or ESP32 using a 18650 Li-Ion battery. The module also features charging electronics that allow you to recharge the lithium batteries via the Micro-USB port.

Caution: When inserting the 18650 lithium batteries, pay attention to the polarity + and -; otherwise, the charging chip will be destroyed.

Recommended accessories:
18650 lithium battery without protection circuitry.

Features:

• Battery protection against overcharging and deep discharge
• Easy charging via Micro-USB or USB Type-C port with up to 0.5A
• Side switch for turning on and off
