HW30840005

Overview

The Hobbywing Capacitor Module Non-Polarity Stand (HW30840005) is a professional-grade power capacitor upgrade specifically designed for the XeRun XR10 PRO G2 ESC, one of the most advanced brushless electronic speed controllers available for 1/10th scale RC racing. This non-polarity capacitor module delivers exceptional performance improvements to your RC car UK racing setup, featuring high-tech SMT-MLCC (Surface Mount Technology Multi-Layer Ceramic Capacitor) construction that safeguards both your ESC and capacitor bank from accidental polarity reversal during battery installation. Whether you're competing in modified or stock class racing, this capacitor upgrade provides the electrical stability and power delivery consistency that serious RC enthusiasts demand.

Built with a capacitance rating of 1700µF, this modified-specification power capacitor module is engineered for racers who prioritise maximum performance and aren't concerned with adding minimal weight to their chassis. The non-polarity design means neither the ESC nor the capacitor bank will suffer damage if you accidentally reverse the battery connections during setup—a common concern for track racers working quickly between heats. This peace of mind, combined with the significant performance gains, makes the HW30840005 an essential accessory for anyone running the XR10 PRO G2 ESC on the track or during competitive practice sessions.

RC car enthusiasts in the UK and beyond have long relied on Hobbywing's reputation for precision engineering and reliability. This capacitor module represents the same commitment to quality and innovation, offering a straightforward bolt-on upgrade that immediately improves your vehicle's electrical performance characteristics without requiring any complex installation procedures or modifications to your existing ESC setup.

Key Features

• Non-Polarity Design — Unlike standard electrolytic capacitors, this module uses high-tech SMT-MLCC construction that protects against reverse polarity installation, meaning neither your ESC nor the capacitor bank will be damaged if battery leads are accidentally reversed during setup, saving expensive repairs and downtime.
• 1700µF Capacitance Rating — The substantial 1700µF capacitance provides excellent electrical stability and power delivery consistency, enabling improved acceleration response and reducing voltage ripple during high-current draw situations common in competitive 1/10th scale racing.
• Low Impedance Construction — The advanced capacitor design minimises electrical impedance, allowing faster current delivery to your motor and ensuring your ESC can respond with maximum precision to throttle inputs during aggressive acceleration phases.
• Low Heat Generation — Professional-grade SMT-MLCC technology generates significantly less heat than standard electrolytic capacitors, improving overall system reliability during extended racing sessions and reducing the thermal stress on your power system components.
• Greatly Improved Start-Up Acceleration — The upgraded capacitor module stores and delivers electrical energy more efficiently, resulting in noticeably quicker launch acceleration off the line, a critical advantage in competitive racing scenarios where every millisecond counts.
• Reduced Ripple Current Interference — By significantly reducing the ripple current endurance in your power system, this capacitor module minimises electrical interference that could otherwise affect servo response, receiver performance, or telemetry systems during operation.
• XR10 PRO G2 Compatibility — This module is specifically engineered for the Hobbywing XeRun XR10 PRO G2 ESC, ensuring perfect electrical integration with that platform's 32-bit M4 microprocessor and advanced power management systems.
• Modified Class Racing Specification — Designed for drivers who want maximum performance without weight restrictions, this modified-spec module delivers superior electrical performance for competitive racing applications in 1/10th scale touring car and buggy classes.

Technical Performance

The Hobbywing HW30840005 capacitor module represents cutting-edge power management technology for brushless RC racing systems. With its 1700µF capacitance rating and advanced SMT-MLCC (Surface Mount Technology Multi-Layer Ceramic Capacitor) construction, this module delivers dramatically improved electrical performance compared to standard capacitor banks. The non-polarity design is particularly significant for serious racers: whilst the XR10 PRO G2 ESC features built-in reverse voltage protection that safeguards the ESC itself, standard electrolytic capacitors offer no such protection. By using this non-polarity capacitor module, you ensure that neither your expensive ESC nor the capacitor bank itself will suffer damage in the event of accidental battery polarity reversal—a scenario that occurs more often than you'd expect during the time-pressured environment of competitive racing.

The module's low impedance design is crucial for modern brushless racing applications. By minimising electrical impedance, the capacitor can deliver current to your motor with maximum efficiency, enabling your ESC's 32-bit M4 microprocessor to achieve extraordinarily fast and precise responses to your throttle inputs. This translates directly into measurably better start-up acceleration—one of the most critical performance metrics in 1/10th scale touring car and buggy racing. The low heat generation characteristics of the SMT-MLCC technology ensure that your power system remains stable even during extended racing sessions, maintaining consistent performance from the first heat through to the finals. When you're operating at the peak performance envelope demanded by modified class racing, every small improvement in electrical stability contributes to more predictable, controllable, and ultimately faster lap times. The HW30840005 is specifically optimised for use with 2S LiPo batteries (the standard for 1/10th scale brushless racing) and integrates perfectly with the XR10 PRO G2's sophisticated power management systems, including its adjustable BEC output and advanced data-logging capabilities.

Frequently Asked Questions

• Will this capacitor module improve my lap times? — Yes, the improved start-up acceleration and reduced electrical ripple directly translate to better performance, particularly in competitive racing scenarios where launch acceleration and mid-corner throttle response are critical. The module enables your XR10 PRO G2 ESC to deliver power more efficiently to your motor, allowing you to extract maximum performance from your racing setup.
• What's the difference between the non-polarity module and standard capacitors? — Standard electrolytic capacitors offer no protection against reverse polarity installation and will be damaged if battery leads are accidentally reversed. This non-polarity module uses high-tech SMT-MLCC construction that protects against reversal, ensuring neither your ESC nor the capacitor bank suffers damage—a critical advantage during time-pressured race day setups.
• Can I use this with the XR10 PRO G2 Elite version? — Yes, the HW30840005 is fully compatible with both the standard XeRun XR10 PRO G2 and the Elite variant (HW30112610, HW30112611, HW30112612), providing identical performance improvements regardless of which ESC version you own.
• Is this suitable for stock class racing? — Whilst this module is specified as the modified class version with 1700µF capacitance, Hobbywing also manufactures a stock class alternative (part number HW30840004) for racers concerned with minimising weight and bulk. For serious modified class competition, this HW30840005 is the correct choice.
• What battery voltage does this support? — This capacitor module is designed for use with 2S LiPo batteries (standard for 1/10th scale brushless racing) or 5-6 cell NiMH batteries, matching the input voltage capabilities of the XR10 PRO G2 ESC itself.
• Will this capacitor get hot during racing? — No, the advanced SMT-MLCC construction specifically minimises heat generation compared to standard electrolytic capacitors, maintaining stable operation even during extended racing sessions and helping to keep your overall power system cooler and more reliable.
• How difficult is installation? — Installation is straightforward—the module mounts directly to your XR10 PRO G2 ESC using the integrated connector system. No soldering or modifications to your existing wiring are required, making it a simple bolt-on upgrade you can perform trackside if necessary.
