Technical Performance

The Hobbywing Capacitor Module "D" represents cutting-edge capacitor technology optimised specifically for 1/10 scale brushless RC car systems. The dual 330?F capacitor banks, each rated at 16V, work in parallel to provide exceptional energy storage capacity and lightning-fast voltage stabilisation. The super low impedance of just 0.002 ohms is the engineering standout here—this specification is measured in milliohms and represents the resistance to AC current flow through the capacitor at high frequencies, meaning energy transfer is virtually loss-free. With a ripple current endurance rating of 24 amps, this module can comfortably handle the transient current spikes that occur when brushless motors draw maximum power during acceleration or direction changes. The construction quality is evident in the low operating temperature characteristics; premium capacitor materials and construction techniques ensure that heat generation is minimised even during sustained high-power operation. The compact dimensions of 29mm x 13mm x 13.2mm are thoughtfully engineered to fit within the tight confines of modern ESC mounting bays, whilst the featherlight 5-gram weight means negligible impact on your vehicle's weight distribution or handling characteristics. For RC enthusiasts in the UK running competitive setups, high-performance bashers, or any serious 1/10 scale RC car application, this module delivers measurable improvements in voltage stability, throttle response, and overall system reliability. The 16V rating makes it compatible exclusively with Hobbywing's Xerun and Ezrun series ESCs, ensuring perfect electrical matching and maximum safety margins during operation.

Frequently Asked Questions

• What ESC models is the Hobbywing Capacitor Module "D" compatible with? — This module is specifically designed for use with Hobbywing's Xerun and Ezrun series ESCs suitable for 1/10 scale RC cars. The model designations covered include 2.1, 3.1, and 10BL60 variants. If you own any of these Hobbywing brushless ESC models, this capacitor module will integrate seamlessly with your existing setup.
• Will this capacitor module improve my RC car's performance? — Yes, absolutely. The Hobbywing Capacitor Module "D" improves performance in several measurable ways: it enhances burst power delivery at acceleration, reduces voltage sag during high-current draws, minimises RF interference for more reliable signal transmission, and stabilises overall electrical performance. You'll notice smoother acceleration, sharper throttle response, and improved consistency during operation, particularly in competitive racing scenarios where every millisecond counts.
• Is installation difficult for someone new to RC cars? — Installation is relatively straightforward for anyone with basic soldering experience, as the module comes with pre-soldered leads ready to connect to your ESC. If you're comfortable with RC car electronics and have soldered connections before, you should have no difficulty installing this module. However, if soldering is new to you, we'd recommend seeking assistance from an experienced RC hobbyist or visiting your local RC retailer for professional installation guidance.
• What makes the 0.002 ohm impedance specification important? — Impedance measures the opposition to AC current flow through the capacitor. The lower the impedance, the more efficiently electrical energy flows through the module with minimal losses. An impedance of 0.002 ohms is exceptionally low, meaning this capacitor module provides virtually unrestricted power delivery to your motor with minimal heat generation or voltage drop, translating to better acceleration response and more reliable performance during intense driving sessions.
• Why should I choose this over other capacitor modules? — The Hobbywing Capacitor Module "D" is engineered specifically by Hobbywing for their own ESC series, meaning the electrical characteristics are perfectly matched to Xerun and Ezrun controllers. This purpose-designed integration, combined with the super low impedance rating of 0.002 ohms, the excellent ripple current endurance of 24 amps, and the proven reliability of Hobbywing's engineering, makes this the optimal choice for 1/10 scale Xerun and Ezrun users. The compact 5-gram weight and precise dimensions also ensure perfect fit within dedicated ESC mounting spaces.
• What is the difference between capacitor modules and other electrical upgrades? — Capacitor modules work fundamentally differently from other electrical components. Whilst ESCs control motor speed and battery chargers manage battery health, capacitor modules stabilise electrical voltage and filter interference in real-time during operation. This means they improve the quality of power delivery to your motor, reducing voltage sag and noise rather than changing how speed or power is controlled. They're particularly valuable additions to high-performance systems where electrical stability directly translates to better driving characteristics.
• Can I use this module with different ESC brands? — This module is specifically engineered for Hobbywing Xerun and Ezrun series ESCs and is optimised for their electrical characteristics and mounting configurations. Using it with other manufacturer ESCs is not recommended, as the electrical matching and physical integration may not be appropriate, potentially compromising safety or performance. Always use manufacturer-approved components for your specific ESC model.
• How does this improve reliability in noisy RF environments? — The capacitor module reduces radio frequency interference by filtering electrical noise generated by the brushless motor and ESC. This filtering makes your RC car's signal transmission more robust and less susceptible to dropout or glitching, particularly important when operating in environments with other RC models running simultaneously or in areas with electromagnetic interference from electrical equipment.
