What is the Hobbywing Platinum 25A V4 ESC?
The Hobbywing Platinum 25A V4 is a brushless electronic speed controller engineered for high-performance RC applications. It supports 3-6S LiPo batteries, delivers 25A continuous current (40A peak), and integrates a high-voltage switch-mode BEC, making it ideal for powering both motors and onboard electronics efficiently.
Its compact design (47 x 22 x 10 mm, 27 g) ensures compatibility with lightweight aircraft while maintaining robust performance.
Key Features That Set It Apart
Advanced 32-bit Processing Power
At the core of the ESC is a 32-bit processor running at 72 MHz, enabling precise throttle response and smooth motor control. This ensures faster signal processing, more accurate speed regulation, and improved flight stability.
DEO Technology (Driving Efficiency Optimization)
Hobbywing’s DEO (Active Freewheeling) technology significantly improves efficiency and performance.
- Faster throttle response
- Reduced heat generation
- Increased energy efficiency
- Extended flight time
High-Voltage Switch-Mode BEC
The built-in BEC provides adjustable output of 6V / 7.4V with 3A continuous current (up to 7A peak). This allows the ESC to power high-performance servos while reducing the need for external modules.
Reverse Brake Function
The ESC includes a reverse brake mode that simulates realistic aircraft landing behavior.
