The Ultimate Stable Power Core! UBEC Step-Down Converter delivers clean, robust 5V power for your FPV drones and RC cars, eliminating voltage noise completely.
Key Features & Benefits
🛡️ Metal Case for Anti-Interference: Full metal shielding provides excellent EMI suppression, ensuring ultra-clean 5V power for sensitive FPV VТXs and receivers.
🎯 Precision Voltage Regulation: Provides a steady 5.25V(±0.5V) output, reliably protecting your core electronics (e.g., FC, RX) from damage caused by voltage fluctuations.
💪 Rugged, Compact & Easy to Integrate: Built for high-vibration RC environments. Durable and space-saving for your builds.
Product Description
Need an absolutely reliable “energy heart” for your model's electronics? This UBEC (Universal Battery Eliminator Circuit) step-down converter is the ultimate solution. It efficiently and quietly converts your high-voltage LiPo battery to a stable 5V rail, optimized specifically for powering FPV systems, RC receivers, servos, flight controllers, ESCs, and other sensitive devices. Whether for racing drones, crawlers, or aircraft, it's the foundation for reliable electronic system operation.
🚨【Critical Risk Control Module - Must Read Before Purchase!】
This is a DC-DC Step-Down Converter Module (UBEC/BEC). It LOWERS battery voltage to stable 5V. It is NOT a boost converter, NOT a charger, and MUST NOT be used to directly power brushless/brushed motors.
【Voltage Match】：ALWAYS select the correct model based on your battery's cell count (nominal voltage)! Double-check the input range before connection.
【Current Match】：The continuous current rating of your chosen model MUST exceed the total operating current of all your 5V devices (RX, servos, FC, LEDs, etc.). We recommend at least a 30% safety margin for peak loads.
【NO Over-Voltage】：Exceeding the maximum input voltage will cause instant and permanent damage!
【Requirements for Use】：
You need a 2S to 8S Lithium Polymer (LiPo) or Lithium-ion (Li-ion) battery as the input source, plus basic soldering or wiring skills.
🔧【Installation & Safety Warnings】：
【Heat Management is Critical】：Ensure good ventilation around the module under high load or in hot environments. Adding a heatsink is strongly recommended for the 15A model under continuous full load.
【Connection Sequence】：Connect the load (OUTPUT) first, then connect the battery (INPUT). Disconnect in reverse order.
【Check Polarity】：Always verify positive and negative connections! Reverse polarity will destroy the module instantly!
