Key Features

• 4.8V Four-Cell Configuration — This battery pack comprises four AA-sized NiMH cells configured in series to deliver a stable 4.8 volts, the standard voltage requirement for most receiver packs in the RC hobby. The four-cell design ensures proper voltage regulation across the full discharge cycle, meaning your receiver maintains consistent power from a fully charged battery down to the moment you need to recharge.
• 2000mAh Capacity for Extended Runtime — With a 2000 milliamp-hour capacity, this battery provides significantly more energy storage than smaller receiver packs, translating directly to longer periods of uninterrupted operation. For competitive RC racing or extended bashing sessions with your RC car or RC truck, the higher capacity means fewer interruptions for battery changes and more time enjoying your model.
• SBS-Flat Profile Design — The SBS-flat (Soft Battery Side Flat) configuration creates a low-profile battery pack with dimensions of just 57mm long, 50mm wide, and only 15mm thick. This exceptionally compact footprint allows for discreet mounting within receiver boxes and tight compartments where traditional cylindrical packs would simply not fit, preserving interior space for other electronics and improving vehicle weight distribution.
• Rx-JR Futaba-Style Connector — Every Radient Superpax battery arrives pre-fitted with the Rx-JR connector, the industry-standard plug type used by Futaba, JR, and the vast majority of modern RC receivers. This universal compatibility eliminates the need for connector adapters or modifications, allowing immediate installation into your receiver box without any additional preparation or soldering.
• Nickel-Metal Hydride Technology — Constructed using proven NiMH chemistry, this battery pack offers reliable, safe operation with excellent cycle life. NiMH batteries are forgiving during charging, tolerant of storage conditions, and deliver consistent performance across a wide range of ambient temperatures, making them ideal for the variable British weather conditions RC enthusiasts face year-round.
• Lightweight 116-Gram Build — Weighing just 116 grams, this receiver battery adds minimal mass to your RC model, helping preserve handling characteristics and overall performance. The low weight-to-capacity ratio makes it an excellent choice for weight-sensitive applications where every gram matters to your model's speed, agility, and responsiveness.
• Suitable for Age 14+ — This battery pack is recommended for RC enthusiasts aged 14 and above, appropriate for experienced hobbyists and younger operators under proper supervision. The robust construction and safe NiMH chemistry make it suitable for responsible users who understand proper battery handling and charging procedures.

Technical Performance

The Radient Superpax NiMH 4.8V 2000mAh AA SBS-Flat battery represents precision engineering optimised for receiver power applications across the full spectrum of RC vehicles. Built using four AA-sized nickel-metal hydride cells configured in series, this pack delivers the regulated 4.8-volt output that modern receiver electronics demand for reliable servo operation and signal processing. The 2000mAh capacity provides substantial energy storage, ensuring stable voltage delivery even under the increased electrical demands of multiple servos working simultaneously during dynamic RC car, RC truck, or RC buggy operation. The materials selected for construction—black nickel-metal hydride cells within the SBS-flat housing—provide proven durability and thermal stability, with cells that can withstand hundreds of charge cycles without degradation when maintained with proper charging practices. The battery's internal resistance is optimised for receiver applications, ensuring minimal voltage sag even during peak current draws when multiple servos operate together. At just 116 grams, the pack achieves an exceptional weight-to-capacity ratio, allowing integration into weight-critical RC applications without compromise. The flat 57x50x15mm profile fits within standard receiver boxes used across virtually all modern RC platforms, from small-scale electric RC cars to larger RC buggies and RC trucks. The pre-soldered Rx-JR connector eliminates the requirement for additional wiring or adapter harnesses, reducing assembly time and potential connection points where problems could occur. This battery performs consistently across the typical temperature ranges encountered in UK RC operating conditions, maintaining voltage stability and power delivery regardless of whether you're running your model on a warm summer afternoon or during cooler autumn sessions.

Frequently Asked Questions

• Is the Radient Superpax 4.8V 2000mAh receiver battery suitable for my RC car? — Yes, this battery is designed specifically for NiMH receiver applications and is compatible with the vast majority of RC cars, RC buggies, RC trucks, and other RC vehicles that use standard receiver boxes and require 4.8-volt power. The universal Rx-JR/Futaba connector means it will work with most modern Futaba, JR, Spektrum, and compatible receivers without adapter harnesses. However, you should confirm your receiver requires a 4.8V NiMH pack rather than a LiPo alternative before purchasing.
• What is the difference between the SBS-flat configuration and a standard battery pack? — The SBS-flat (Soft Battery Side Flat) design creates an exceptionally low-profile battery with a 15mm thickness, compared to traditional cylindrical AA-style packs that can be significantly taller. This flat design fits neatly within most receiver boxes and alongside other components, making it the preferred choice when space is limited. If you have space constraints in your receiver compartment, the SBS-flat design is superior to traditional configurations.
• How long will the 2000mAh capacity keep my RC model running? — Runtime depends on your specific RC setup, the number of servos you're operating, and how actively you're commanding steering and throttle inputs. Typically, a 2000mAh receiver pack in an RC car or RC truck will provide 30 minutes to several hours of operation before requiring a recharge. The higher 2000mAh capacity provides significantly longer runtime than smaller 1500mAh packs, reducing the need for frequent battery changes during extended RC sessions.
• Is this battery compatible with Futaba and JR receivers? — Yes, absolutely. The Rx-JR connector is the industry-standard plug used by both Futaba and JR receivers, as well as compatible receivers from other manufacturers. The battery arrives pre-fitted with this connector, requiring no adapters or modifications for immediate installation.
• Do I need to charge this battery before first use? — Yes, like all NiMH batteries, the Radient Superpax should be charged using an appropriate NiMH battery charger before initial use. Most NiMH chargers are designed to safely charge 4.8V four-cell packs, and the charging process typically takes 1-3 hours depending on your charger's specifications. Always follow the manufacturer's charging guidelines to ensure safe operation and maximise battery lifespan.
• Can I use this battery in my RC aircraft as well as my RC car? — Yes, the 4.8V 2000mAh Superpax is suitable for any RC application requiring receiver power, including RC aircraft, RC helicopters, RC boats, and other RC vehicles. The compact size and light weight make it particularly well-suited to applications where space and weight are critical factors, such as small-scale RC planes or RC drones.
