Frequently Asked Questions

• What are XT90 connectors and why are they better than other RC power connectors? — XT90 connectors have become the industry standard for high-current RC applications because they offer superior contact surface area compared to smaller connectors like T-plugs or Deans connectors, resulting in lower electrical resistance, reduced voltage drop, and less heat generation during power delivery. This means your RC motor receives more of the available battery voltage, translating to better performance and efficiency in your RC vehicle. The larger physical design also makes them easier to handle and solder, reducing the risk of connection errors.
• What does anti-spark technology mean, and why does it matter for my RC system? — Anti-spark technology uses mechanical design features to prevent electrical arcing (sparking) when you connect or disconnect the battery from your RC electronics. Arcing can damage your RC ESC, create voltage spikes that destroy sensitive components, and shorten battery life. By minimising arcing, anti-spark connectors protect your entire RC electrical system and make battery swaps safer and more reliable.
• Will I need soldering equipment to use these connectors? — Yes, these XT90 connector pairs require basic soldering skills to attach to your battery leads and power cables. You'll need a soldering iron, solder suitable for electrical applications, and ideally some flux to ensure good solder joints. If you're new to soldering RC connectors, we recommend watching instructional videos or asking experienced RC enthusiasts for guidance to ensure your connections are solid and safe.
• Are these connectors compatible with my RC battery? — These XT90 connector pairs are compatible with any XT90-equipped RC battery, RC charger lead, or RC power adapter. If your battery currently uses a different connector type like Deans, T-plug, or XT60, you would need to either replace the battery connector or create an adapter using these pairs. Many RC hobbyists in the UK prefer upgrading to XT90 for their entire fleet because of the superior performance and safety characteristics.
• How many connector pairs do I actually need? — The number of pairs you need depends on your RC setup. You'll want one pair for each power lead you're building or one pair if you're creating an adapter between two different connector types. This set of five pairs gives you flexibility to build multiple leads, create adapters, or keep spares on hand—ideal for RC enthusiasts maintaining multiple RC vehicles or creating redundant charging systems.
• Can I use these for high-amperage RC applications like competitive racing? — Absolutely. XT90 connectors are designed specifically for high-current applications and are the preferred choice for competitive RC racing where sustained currents of 80-150+ amps are common. The anti-spark design is particularly valuable in racing scenarios where equipment reliability and performance consistency are paramount.
• What's the difference between XT90 and XT90-S (anti-spark) connectors? — These Radient pairs feature anti-spark technology built into the connector design, which is the XT90-S specification. The anti-spark feature adds mechanical components that prevent arcing during connection and disconnection, making them safer and more protective of your RC electronics compared to standard XT90 connectors without anti-spark capability.
• Is this suitable for beginners? — These connectors are recommended for RC enthusiasts aged 14 and upwards with basic soldering experience. If you're completely new to RC and haven't soldered connectors before, you might consider purchasing pre-assembled XT90 leads initially, then progressing to these pairs once you've developed soldering skills and connector experience with simpler projects.
