Overview
The Traxxas 2A DC NiMH 5-7 Cell Charger TRX2974 is a reliable, fast-charging solution designed specifically for RC enthusiasts who run NiMH battery-powered models. Whether you're a dedicated RC car UK hobbyist, a weekend basher, or someone looking to expand your ready to run RC collection, this charger delivers professional-grade performance at an accessible price point. The 2-amp output provides rapid charging capability whilst the intelligent peak-detection circuitry ensures your batteries receive a complete, optimised charge every single time, maximising runtime and extending battery lifespan.
This charger is engineered for universal high-output charging from a standard 12-volt DC power outlet, making it incredibly versatile for use at home, in the workshop, or even at the track. It's specifically optimised for charging 5-7-cell Traxxas iD Power Cell NiMH batteries (equivalent to 6-volt to 8.4-volt systems), which are commonly found across a wide range of Traxxas electric RC models. If you're serious about keeping your fleet of RC vehicles ready to race or bash, the TRX2974 is an essential piece of equipment that will pay for itself through reliable, efficient charging performance.
The charger features foolproof operation with visual feedback via an intelligent status LED system. Unlike confusing chargers with cryptic indicators, this Traxxas model uses a simple green LED that flashes during active charging and turns solid green when your battery is fully charged—eliminating any guesswork and giving you confidence that your batteries are properly conditioned for peak performance.
Key Features

Technical Performance
The Traxxas 2A DC NiMH Charger represents a mature, time-tested charging solution that has become standard issue for many RC car UK enthusiasts running NiMH-equipped models. The 2-amp output strikes an excellent balance between charging speed and thermal management, allowing most 5-7 cell NiMH packs to reach full charge in approximately 1-2 hours depending on battery capacity. The peak-detection circuitry is the engineering heart of this charger—it continuously monitors battery voltage throughout the charging cycle and automatically terminates charging the instant the battery reaches full capacity. This prevents the common problem of trickle charging, which generates excessive heat and degrades NiMH cell chemistry over repeated charge cycles. The charger's build quality reflects Traxxas's reputation for robust, field-proven equipment. The robust power supply is designed to handle the sustained current draw of 2-amp charging without voltage sag or thermal stress. For brushed and brushless RC vehicles powered by NiMH batteries—from entry-level RTR models to race-ready competition machines—this charger provides the electrical reliability and charging intelligence that serious hobbyists demand. The 12-volt DC input is also worth noting: it means the charger can be powered from a dedicated 12V power supply, a vehicle's auxiliary outlet adapter, or a workshop 12V DC bench supply, making it exceptionally flexible for different operational environments.

Frequently Asked Questions
- What batteries does the Traxxas TRX2974 charger work with? — This charger is specifically designed for NiMH batteries only, optimised for 5-7 cell Traxxas iD Power Cell NiMH batteries in the 6-volt to 8.4-volt range. It is not compatible with LiPo or LiIon batteries, as these require completely different charging profiles and safety protocols. The charger's circuitry is calibrated exclusively for NiMH chemistry to ensure safe, optimal charging.
- Is this charger suitable for beginners? — Absolutely. The TRX2974 is one of the most beginner-friendly chargers available. Unlike programmable chargers with complex menus, this model features automatic operation—simply connect your NiMH battery, and the charger handles everything via its intelligent peak-detection system. The visual LED feedback (flashing green during charging, solid green when complete) makes it impossible to misuse or overcharge your batteries accidentally, making it ideal for those new to the RC hobby.
- How long does it take to charge a typical NiMH battery? — Charge time depends on battery capacity and your specific pack. With a 2-amp output, most standard NiMH packs used in ready to run RC models will charge in 1-2 hours. Higher-capacity racing batteries may require longer. The peak-detection circuitry ensures the charger stops at full capacity, so you can safely leave your battery charging without risk of overcharge damage.
- What power supply do I need for this charger? — The TRX2974 requires a 12-volt DC power input. This can come from a dedicated 12V power supply, a workshop bench supply, or a vehicle cigarette lighter adapter (12V output). You cannot use mains AC power directly—you must have a DC power source rated for 12 volts.
- Can I charge LiPo batteries with this charger? — No. This charger is designed exclusively for NiMH batteries. Do not attempt to use it with LiPo, LiIon, or any other lithium chemistry batteries. Charging lithium batteries with an NiMH charger will damage the charger and may cause dangerous battery failures. Always match your charger type to your battery chemistry.
- Why choose NiMH batteries and chargers in 2024? — Whilst brushless RC and LiPo technology have become dominant in the hobby, NiMH remains popular for several reasons: lower cost of entry, excellent durability and resilience to abuse, simpler charging infrastructure, and proven reliability across thousands of ready to run RC models. Many classic Traxxas models and older RC vehicles still run NiMH, making this charger a practical necessity for collectors and enthusiasts with established NiMH fleets.
