4S-6S 12V 3A UBEC

This 4S-6S 12V 3A UBEC (Universal Battery Eliminator Circuit) converts high-voltage input from a 4S to 6S LiPo battery (up to 25V) to a stable 12V output at 3A. It is designed for drones, robots, and other UAS projects where the ESC lacks a built-in BEC or a standalone power supply is required.

Specifications

• Input voltage: 4S–6S LiPo (14.8V–25.2V)
• Output: 12V DC, 3A continuous
• Efficiency: >85% typical
• Protection: Over-current, over-voltage, short-circuit
• Dimensions: 45mm x 25mm x 10mm
• Weight: 12g

Compatible with

• Arduino boards (Uno, Mega, Nano)
• ESP32 and ESP8266
• Raspberry Pi (3B+, 4, Zero)
• STM32 development boards
• Pixhawk and other flight controllers

What you can build with it

• FPV drone power system — run camera, VTX, and flight controller from one LiPo
• Robotic arm controller — power servos and microcontroller from a single battery
• Portable 12V test bench — supply clean power to sensors and modules in the field
