Overview
The FTX Tracer Hi-Capacity Li-Ion 7.4V 1500mAh Battery Pack is a premium power solution designed specifically for brushed RC cars and trucks. Whether you're piloting an FTX Tracer 1/16 RTR Monster Truck, an FTX Tracer 1/16 RTR Truggy, or a compatible Blackzon Slyder model, this high-capacity battery delivers extended runtime and reliable performance on every charge. If you're searching for a dependable RC battery UK retailers recommend, or looking to upgrade your brushed RC car's power system, this Deans connector equipped pack represents excellent value and proven compatibility across multiple platforms.
Built using advanced Li-Ion technology, this battery pack offers significantly more capacity than standard factory batteries, meaning longer play sessions and less time waiting between charges. The 7.4V two-cell configuration (2S) provides the perfect voltage for brushed motors and ESC systems, whilst the 1500mAh capacity strikes an ideal balance between weight, performance and extended runtime. This is the upgrade choice for serious RC enthusiasts who demand more from their brushed RC vehicle, whether they're weekend bashers enjoying casual outdoor driving or competitive racers looking for consistent power delivery throughout their session.
RC Model Shop stocks this battery as an official FTX authorised retailer, meaning you receive a genuine product with full manufacturer support and quality assurance. The Deans connector ensures secure, reliable electrical connection with standard brushed ESC and motor setups, whilst the compact dimensions allow installation in tight battery bays—though you will need to remove the factory foam padding strip to accommodate the increased capacity.
Key Features
- High-Capacity 1500mAh Li-Ion Cell — The significantly larger capacity compared to standard batteries means you'll enjoy substantially longer running time before needing to recharge, allowing you to maximise your RC driving sessions without constant battery swaps.
- 7.4V 2S Li-Ion Chemistry — This voltage specification is perfectly matched to brushed motor and speed controller systems, delivering consistent power output and optimal performance characteristics for your FTX Tracer or compatible brushed RC car.
- Deans Connector — The Deans connector is the industry-standard connection type for brushed RC vehicles, ensuring secure and reliable electrical connection with your ESC and charger without any compatibility concerns.
- Compact Dimensions — Measuring just 55 x 35 x 20mm in size, this battery pack is engineered to fit within the tight confines of 1/16 scale RC vehicle battery bays, making it ideal for smaller brushed RC cars and trucks.
- Genuine FTX Product — Manufactured by FTX and supplied through authorised UK retailers like RC Model Shop, this battery carries full manufacturer support, quality control standards, and genuine specifications you can trust.
- Multiple Platform Compatibility — Beyond the FTX Tracer range, this battery is confirmed compatible with all Blackzon Slyder Stadium Truck and Blackzon Slyder Monster Truck variants, giving you flexibility in your RC collection.
- Brushed Motor Optimised — This battery is specifically designed and tested for use with brushed motor systems and compatible ESC units, ensuring optimal performance and safe operation with these power systems.
Technical Performance
The FTX Tracer Hi-Capacity Battery Pack represents a substantial upgrade in energy storage for brushed RC vehicles in the 1/16 scale class. With 1500mAh of Li-Ion capacity at 7.4V, this battery delivers approximately 11.1 Watt-hours of total energy, translating to noticeably longer runtime compared to factory-standard batteries. The two-cell (2S) configuration provides the correct voltage range for brushed motors operating within a typical 6-8V window under load, ensuring your motor receives optimal power delivery without over-voltage stress. Li-Ion technology offers superior energy density compared to older NiMH batteries, meaning this 1500mAh pack weighs significantly less whilst storing more energy—a critical advantage in small-scale RC vehicles where every gram affects handling and acceleration. The compact physical dimensions (55 x 35 x 20mm) are engineered to squeeze into the battery compartments of FTX Tracer models and Blackzon Slyder variants, though the increased capacity does mean the pack is slightly larger than factory batteries, necessitating removal of the factory foam padding strip for proper installation. Build quality is assured through FTX's manufacturing standards and the internationally recognised Deans connector, which provides low-resistance electrical contacts for efficient power delivery and minimal voltage drop during peak current draw. This battery is recommended for use with brushed ESC and motor combinations rated for 7.4V input, making it ideal for the stock equipment found in FTX Tracer Ready-to-Run kits and Blackzon Slyder vehicles across all colour variants and body styles.

Frequently Asked Questions
- Is the FTX Tracer Hi-Capacity Battery compatible with my Blackzon Slyder? — Yes, this battery is explicitly confirmed compatible with all Blackzon Slyder Stadium Truck and Blackzon Slyder Monster Truck models across all available colour variants including red, orange, blue, green and yellow versions, making it an excellent upgrade choice if you own a Slyder RC truck.
- Will this battery fit in my FTX Tracer without modification? — The battery will fit inside your FTX Tracer's battery compartment, but you will need to remove the foam strip that pads out the standard battery holder to make room for this higher-capacity pack, as it is slightly larger than the factory battery.
- What charger do I need for this battery? — This 7.4V Li-Ion battery requires a charger specifically designed for Li-Ion cells with a Deans connector input. Most modern RC chargers and the chargers supplied with FTX Tracer RTR kits are compatible, but always verify your charger supports Li-Ion and 2S battery packs before use.
- How much longer will this battery last compared to the standard battery? — With 1500mAh capacity, this battery provides approximately 50% more energy storage than typical 1000mAh factory batteries, meaning you can expect roughly 50% longer runtime on a single charge, though actual runtime depends on your driving style and motor power consumption.
- Is this battery suitable for beginners? — Yes, absolutely. This is a straightforward Li-Ion battery pack designed for standard brushed motor systems in ready-to-run RC vehicles. If you already own an FTX Tracer or Blackzon Slyder RTR kit, simply charging this battery using your charger and connecting it via the Deans connector is all that's required—no technical expertise needed.
- What makes Li-Ion better than NiMH batteries? — Li-Ion technology provides higher energy density, meaning more power in the same or smaller physical size, no memory effect so you can charge whenever you like, and superior power delivery characteristics. Li-Ion batteries also maintain more consistent voltage throughout the discharge cycle, delivering more stable performance compared to older NiMH chemistry.
- Can I use this battery in other RC vehicles? — This battery is designed for brushed motor systems that operate at 7.4V with a Deans connector. If you have other RC cars, brushless RC trucks, or brushed vehicles with different connectors, compatibility would need to be verified with the specific vehicle manufacturer, though FTX and Blackzon Slyder products are the confirmed platforms for this pack.
