USB Power Supply 18650 Lithium Battery BMS for Arduino (5V/3V Output, 5V Charger)

Reference: #1590

R 114.80 In Stock (33)

Introducing the USB Power Supply 18650 Lithium Battery BMS for Arduino, a high-quality and versatile power supply solution for your electronic projects. This power supply module is designed to be used with Arduino boards and other microcontrollers, offering reliable and stable power output to your projects.

At its core, this power supply module is powered by a single 18650 lithium battery, which provides a long-lasting and powerful energy compared to most other batteries.

Using three 3V batteries is much more efficient at powering your arduino than the standard 9V battery. Your device will have longer run-time due to the hige increase in efficiency. The only better mobile power supply than this is to use Lithium Batteries for your Arduino.

This battery module connects directly to your Arduino's USB port.
