Overview
The Radient 4.0mm HXT Pairs Connector With Polarity Housing (10 pcs) is an essential spare part and connectivity solution for RC enthusiasts across the UK who work with HXT-style power connectors. Whether you're building multiple RC cars, maintaining a growing fleet of battery packs, or simply need reliable replacement connectors for your ESC and battery leads, this value pack delivers exactly what you need. HXT connectors have become a standard choice in the RC hobby community, offering secure, reliable power connections for everything from electric RC cars to battery management systems.
Each pair in this 10-pack includes polarity housing, which is a critical safety and usability feature that helps ensure correct orientation every single time you connect your battery or ESC. This eliminates the risk of reverse polarity connections that could damage your electronics or cause dangerous battery failures. If you're a regular RC car builder in the UK, whether you're into brushless RC buggy builds, RC monster truck upgrades, or general RC power applications, having a stock of quality HXT connectors is absolutely essential for fast, efficient builds and repairs.
Supplied by Radient under part number RDNAC010108, this pack represents outstanding value for money, giving you ten complete connector pairs in a single purchase. Recommended for ages 14 and above, this product is perfect for hobbyists who want to standardise their connector infrastructure across multiple builds, or for experienced RC enthusiasts who maintain several vehicles and need reliable spares on hand.
Key Features
- HXT 4.0mm Connector Standard — These connectors conform to the widely-adopted HXT 4.0mm specification, ensuring compatibility with the vast majority of modern RC batteries, ESCs and charge leads that use HXT-style plugs. This standardisation means you can work seamlessly across different brands and builds without worrying about proprietary connector incompatibilities.
- Polarity Housing Included — Each pair comes with integrated polarity housing that physically prevents reverse-polarity connections, protecting your expensive RC electronics from potential damage and ensuring safe battery management every single time you connect power to your vehicle.
- Ten Complete Pairs Per Pack — This is a genuine value bundle containing ten male-female connector pairs, giving you the flexibility to create multiple new leads, refresh aging connectors on existing batteries, or build up a comprehensive spare parts inventory for your RC workshop.
- Straightforward Installation — HXT connectors are soldered directly to your leads and require no specialist tools or adapters, making them ideal for anyone with basic soldering skills who wants to maintain control over their RC power infrastructure.
- Suitable for Multiple RC Applications — Whether you're working with RC batteries, ESC connections, charge leads, or general RC power applications employing HXT-style plugs, these connectors deliver the versatility and reliability you need.
- Genuine Radient Brand Quality — Radient is a recognised manufacturer of RC connectors and power management accessories, ensuring that each connector in this pack meets consistent quality standards and delivers long-term reliability.
Technical Performance
The Radient 4.0mm HXT connectors are engineered to handle the demanding power requirements of modern RC vehicles and battery systems. HXT 4.0mm connectors are rated for high-current applications typical in brushless RC car builds, making them suitable for use with standard 2S, 3S and 4S LiPo battery packs commonly used in 1/10-scale RC cars and similar RC vehicles. The polarity housing design is a critical engineering feature that prevents potentially catastrophic reverse-polarity mistakes—a single wrong connection could deliver reversed voltage to your ESC or motor controller, causing instant damage. The 4.0mm plug diameter provides excellent mechanical stability and secure contact force without being oversized or cumbersome. Each connector pair is manufactured to consistent specifications, ensuring reliable performance across all ten pairs in the pack. The design is particularly popular among UK RC enthusiasts who appreciate the balance between robust current handling capability and compact, practical connector sizing that doesn't add significant weight or bulk to RC leads.

Frequently Asked Questions
- What are HXT 4.0mm connectors and why do I need them? — HXT 4.0mm connectors are industry-standard power connectors widely used in the RC hobby for connecting batteries to ESCs and charging leads. The 4.0mm designation refers to the plug diameter. They've become the de facto standard in RC because they offer a good balance of current-carrying capacity, compact size, and mechanical reliability. If you own multiple RC cars or regularly build new vehicles, having spare HXT connectors allows you to quickly create new leads, repair damaged connectors, or standardise your entire fleet on the same connector type for convenience and consistency.
- What is polarity housing and why does it matter? — Polarity housing is a physical moulded feature on the connector that prevents you from accidentally inserting the plug backwards. Reverse polarity connections can instantly destroy expensive ESC electronics or cause dangerous battery failures. The polarity housing on Radient connectors ensures that the male and female connectors can only connect one way, eliminating this risk entirely. This is a crucial safety and protection feature that every RC enthusiast should prioritise when choosing connectors.
- Are these connectors suitable for my RC car battery and ESC? — HXT 4.0mm connectors are compatible with any RC battery, ESC, or charge lead that features HXT 4.0mm connectors. This includes batteries and controllers from multiple manufacturers. However, you should verify that your specific components use HXT connectors rather than other standards like XT60, Dean's, or Anderson connectors. Check your battery pack documentation or ESC manual to confirm compatibility before purchasing.
- How many connector pairs do I actually need? — This 10-pack gives you excellent flexibility. If you're building a single new lead, you need just one pair. If you're maintaining multiple RC vehicles or building several new leads, ten pairs provides plenty of spares. Many UK RC enthusiasts keep several packs on hand as general workshop inventory since connectors are consumable items that occasionally need replacement due to wear, damage, or corroded contacts.
- Are these suitable for beginners? — HXT connector installation requires soldering skills, as the connector pins must be soldered directly to your power leads. If you're comfortable with basic soldering (holding a soldering iron, managing solder flow, and creating clean joints), then yes, you can install these connectors. If you've never soldered before, you might want to practise on spare wire first or purchase pre-made connector leads while you develop your skills. The connectors themselves are robust and forgiving once installed correctly.
- What is the difference between HXT and other RC connectors like XT60? — HXT 4.0mm connectors are physically smaller and more compact than XT60 connectors, making them popular in 1/10-scale and smaller RC vehicles where space is at a premium. XT60 connectors are larger and rated for higher current, making them more common in 1/8-scale buggies and larger vehicles. HXT connectors are also generally less expensive. The connectors are simply different standards; compatibility depends on what your specific RC components use.
