Key Features
- XT90 Connector Standard — The XT90 connector format has become the recognised standard for high-current RC applications across the UK and worldwide, ensuring broad compatibility with modern battery packs and charging systems, and meaning you can confidently expand your power infrastructure.
- Series Configuration — This Y connector allows you to link two XT90-equipped power sources in series, which increases your total system voltage and provides the higher power delivery needed for demanding RC applications like brushless RC trucks and competitive racing vehicles.
- 12AWG Wiring Gauge — The 12 American Wire Gauge specification provides excellent current handling capability with minimal resistance, ensuring that power is delivered efficiently from your battery packs to your speed controller and motor with minimal voltage drop, which is critical for maintaining performance.
- 100mm Lead Length — The 100 millimetre length strikes a practical balance between flexibility in battery arrangement and the rigidity needed to maintain solid connections, giving you room to position your battery packs sensibly within your RC chassis without excess cable bulk.
- Robust Construction — Built to withstand the demands of active RC use, this connector is engineered to provide reliable, repeatable connections that won't fail during critical moments in races or bashing sessions.
- Age Appropriate — Designed for users aged 14 and upwards, this connector is suitable for intermediate RC builders and operators who have experience with power management and battery handling in their ready to run RC models.
Technical Performance
The Radient XT90 Series Y Connector delivers genuine performance benefits for serious RC car UK builders. The 12AWG wire gauge is carefully selected to handle the high currents that modern brushless RC motors and speed controllers demand without introducing excessive resistance. In series configuration, this connector allows you to combine two battery packs effectively, increasing total voltage whilst maintaining the current capacity of a single pack – this is particularly valuable for users pushing their RC trucks and buggies to their limits. The XT90 connector itself features a robust mechanical design with spring-loaded contacts that ensure positive connection every time, eliminating the intermittent power issues that can plague inferior connector designs. The engineering focuses on both electrical performance and mechanical durability, meaning this connector will maintain its connection integrity through countless charge cycles and intensive use. The 100mm lead length has been chosen to accommodate typical RC chassis layouts without creating cable management problems, and the quality of the wiring insulation ensures safe operation even in the demanding thermal environment of a high-performance RC setup.

Frequently Asked Questions
- What does a series Y connector do for my RC setup? — A series Y connector allows you to link two battery packs together in series, which increases your total system voltage. For example, connecting two 3S LiPo packs in series gives you 6S voltage, which can significantly increase the performance of your brushless RC motor and speed up your ready to run RC model. This is particularly popular among RC car UK users running high-performance buggies and trucks.
- Is this suitable for beginners? — This connector is recommended for users aged 14 and upwards with experience in RC battery management and power systems. Beginners should ensure they understand series battery configurations and voltage management before using series connectors, as improper use could damage ESCs or create safety issues. We recommend consulting detailed guides or asking our experienced team before deploying dual-battery setups.
- What batteries can I use with this connector? — The Radient XT90 Series Y Connector is compatible with any XT90-equipped batteries, which includes most modern LiPo packs from leading manufacturers. The 12AWG wiring can safely handle the currents from most 3S and 4S packs in series configuration, though you should verify that your speed controller can handle the resulting voltage – typically up to 8S maximum for most brushless RC applications.
- Why use 12AWG wiring instead of thicker gauge? — The 12AWG gauge provides an excellent balance between current-carrying capacity and flexibility. It's thick enough to handle currents from dual-pack setups with minimal voltage drop, yet flexible enough to route through RC chassis and allow reasonable battery positioning. Thicker gauges would be unnecessarily rigid and difficult to manage in typical RC installations.
- Can I use this with my ready to run RC model? — Yes, provided your ready to run RC model has XT90-equipped batteries and your speed controller supports the voltage of a series-connected configuration. Many modern ready to run RC cars, trucks, and buggies feature XT90 connectors, making this a straightforward upgrade for compatible models.
- What is the difference between this and single-pack XT90 leads? — This Y connector is specifically designed to link two battery packs together in series configuration, whereas standard XT90 leads simply connect a single pack to your vehicle. The Y design with two input leads allows proper series connection with correct polarity management, whereas regular leads would not provide the parallel connection points needed for this configuration.
