Overview
The FTX Tracer USB Balance Charger (FTX9737) is an essential charging solution designed specifically for owners of FTX Tracer 1/16 scale RC monster trucks and truggies. Whether you're a dedicated basher pushing your ready to run RC car to its limits, or a casual enthusiast enjoying weekend sessions with your FTX Tracer, this compact USB charger delivers convenient, reliable battery charging wherever you are. The integrated balance charging technology ensures your Li-Ion batteries maintain perfect cell balance, extending battery life and maintaining consistent performance across every session.
This USB-powered charger represents excellent value for FTX Tracer owners in the UK, offering a practical charging solution that doesn't require expensive mains-powered equipment. If you own an FTX Tracer 1/16 RTR Monster Truck or FTX Tracer 1/16 Truggy in any colour variant—orange, red, blue, green, or yellow—this charger is purpose-built to keep your batteries in peak condition. The intelligent balance charging system continuously monitors each cell in your 7.4V Li-Ion battery pack, automatically adjusting charge parameters to prevent overcharging and cell imbalance, which are common causes of battery degradation in budget-conscious RC setups.
Designed with practicality at its heart, the FTX Tracer USB Balance Charger plugs into any standard USB power adapter (2A or higher recommended), making it perfect for charging at home, at the track, in the office, or even while travelling. This flexibility makes it an ideal accessory for RC enthusiasts who want to maximise track time without worrying about battery management or complicated charger setups.
Key Features
- Built-in Balance Charging — The integrated balancer continuously monitors your 7.4V Li-Ion battery cells during charging, automatically equalising voltage across all cells to prevent dangerous imbalances that can reduce performance and shorten battery life. This is crucial for maintaining consistent power delivery during competitive racing or casual bashing sessions.
- USB Power Input — Unlike traditional mains chargers, the FTX9737 draws power directly from any USB adapter with at least 2A output capacity, eliminating the need for bulky mains-powered equipment and making it incredibly portable for RC bashers on the move.
- Optimised for FTX Tracer Vehicles — This charger is specifically designed and tested for compatibility with the complete range of FTX Tracer 1/16 scale monster trucks and truggies, including the brushless variants, the standard RTR models, and all factory colour options available in the UK market.
- Wide Input Voltage Range — Accepting DC input from 5V to 12V, this charger works with multiple USB power sources, including standard USB mains adapters, laptop chargers, power banks, and USB car chargers, providing flexibility for charging almost anywhere.
- Safe 1.3A Charging Current — The 1.3A charging rate delivers a balance between speed and battery safety, ensuring your Li-Ion cells are charged without thermal stress or damage, extending the overall lifespan of your battery investment.
- Compact and Portable Design — The small footprint makes this charger perfect for storing in your RC car bag, glove box, or pit box, ensuring you're never without a way to charge your batteries at the track or during travel.
Technical Performance
The FTX Tracer USB Balance Charger represents intelligent battery management engineering designed for the 1/16 scale RC market. Operating with a DC input range of 5V to 12V, the charger delivers a controlled 1.3A charging current specifically calibrated for the 7.4V Li-Ion battery packs found in FTX Tracer monsters trucks and truggies. The built-in balance charging circuit continuously monitors cell voltage during the charging cycle, automatically routing current to ensure all cells within your battery pack reach the same voltage level simultaneously. This prevents the dangerous condition of cell imbalance, where one cell reaches full charge before others, which inevitably leads to reduced performance, shortened battery life, and potential safety issues. The charger's intelligent design means you simply connect your battery and USB power source—no complex programming, no dip switches, no confusion about charge rates or battery types. For optimal performance, FTX recommends using a USB power adapter with at least 2A output capacity, ensuring the charger receives sufficient power to deliver its full 1.3A charging capability without voltage sag or inconsistent charging behaviour. Whether you're charging a single battery between runs or maintaining multiple battery packs for your collection of FTX Tracer vehicles, the USB format makes this charger incredibly practical for UK RC enthusiasts.

Frequently Asked Questions
- Is the FTX Tracer USB Balance Charger compatible with all FTX Tracer models? — Yes, this charger is designed to work with all FTX Tracer 1/16 scale vehicles, including the standard RTR Monster Truck variants (orange, red, blue), the Brushless Tracer 1/16 models (yellow, blue, red), and all Truggy variants (orange, red, green). All of these models use 7.4V Li-Ion batteries, making them fully compatible with this charger.
- What USB power adapter do I need to use with this charger? — Any standard USB power adapter with at least 2A output capacity will work with the FTX Tracer USB Balance Charger. This includes common USB-A adapters, laptop chargers with USB output, or modern USB-C adapters. The charger's wide input voltage range (5V-12V) means you have flexibility in power source selection.
- How long does it take to charge a 7.4V Li-Ion battery? — Charge time depends on the capacity of your battery pack and the 1.3A charging current, but typically a standard FTX Tracer battery will charge in 2-4 hours. The exact time varies based on battery capacity and remaining charge level.
- Is this charger suitable for beginners? — Absolutely. The FTX Tracer USB Balance Charger is one of the most beginner-friendly charging solutions available for RC vehicles in the UK. There are no complicated settings, no programming required, and no need to understand Li-Ion chemistry—simply plug in your battery and power source, and the integrated balance charging system handles everything automatically.
- What makes balance charging important for my RC batteries? — Balance charging ensures all cells in your 7.4V battery pack (which contains two 3.7V cells in series) charge to exactly the same voltage level. Without balance charging, cells can develop voltage imbalances over time, which reduces performance, shortens battery life, and can create safety hazards. The integrated balancer in this charger continuously prevents this from happening.
- Can I use this charger with other battery types? — No, this charger is specifically designed for 7.4V Li-Ion batteries. Do not attempt to charge other battery chemistries such as NiMH, NiCd, or LiPo batteries, as this may cause damage or safety issues.
- Is the FTX9737 charger portable enough for taking to the track? — Yes. The USB format makes this one of the most portable battery charging solutions available. Combined with a lightweight USB power adapter or portable power bank, you can easily carry this charger in your pit box or RC car bag, making it perfect for track days or travel.
