• Low Profile Stick Pack Design — The compact stick pack form factor fits neatly into standard battery trays in most RC vehicles, offering excellent space efficiency without compromising capacity or performance. This design makes it compatible with a wide range of RC models from different manufacturers.
• Developed with Leading Manufacturer — Created in partnership with one of the world's top battery manufacturers, this Voltz pack combines proven engineering and quality control standards. You're getting genuine, tested technology rather than a generic alternative, with performance you can rely on.

Technical Performance

The Voltz VZ0342EC5 LiPo battery pack delivers impressive technical performance specifications tailored for high-demand RC applications. With a continuous discharge rate of 50C, this battery can supply up to 200A of continuous current (4000mAh × 50C = 200A), making it exceptionally well-suited for brushless motor systems that demand rapid current delivery. The 11.1V nominal voltage (3S configuration) is the sweet spot for 1/10 and 1/8 scale RC cars, trucks, buggies, and crawlers, providing smooth power characteristics and optimal compatibility with standard ESC (Electronic Speed Controller) systems found in most modern RC vehicles. The 44.4 Watt Hour energy rating provides substantial runtime for extended driving sessions, whether you're enjoying casual weekend bashing or competitive racing at your local RC club. The hard case construction uses durable materials designed to withstand the rigours of RC driving, protecting the internal cells from mechanical damage whilst keeping weight to a minimum. The dimensions of 138mm × 46mm × 38mm make this a practical choice for vehicles with standard battery compartments, fitting comfortably alongside other components without requiring modifications. The EC5 connector, a gold-plated high-current connection system, ensures minimal voltage drop during discharge, allowing maximum power to reach your motor and ESC. This battery works seamlessly with any compatible LiPo charger supporting standard charge protocols, and the pre-fitted connector means you can charge immediately without additional adapters or soldering work.

Frequently Asked Questions

• Is the Voltz 4000mAH LiPo battery suitable for beginners and RTR models? — Yes, absolutely. This battery is specifically described as ideal for RTR (ready to run) models and is an excellent upgrade for brushless models supplied without batteries. However, beginners should ensure they have a compatible LiPo charger and understand safe LiPo handling and storage procedures before use. The EC5 connector and hard case make it beginner-friendly, as there's no soldering required.
• What RC vehicles is this battery compatible with? — The Voltz 4000mAH 11.1V 50C battery is suitable for all radio control vehicles with 3S LiPo compatibility, including 1/10 and 1/8 scale RC cars, trucks, buggies, and crawlers. It works with both brushless and brushed motor systems, making it incredibly versatile. Common compatible vehicles include RC monster trucks, RC buggies, RC stadium trucks, RC short course trucks, and RC crawlers from manufacturers like Traxxas, ARRMA, Losi, and FTX.
• How long does this battery last on a single charge? — Runtime depends on your specific RC vehicle, driving style, and motor system. The 4000mAh capacity is substantial and will provide extended driving sessions. With a 50C discharge rate, the battery can deliver high current continuously, supporting aggressive driving without voltage sag. Typical runtime ranges from 15-30 minutes depending on load, but you should have a second battery charged and ready for back-to-back sessions.
• What charger do I need for the Voltz LiPo battery? — You'll need a LiPo-compatible charger that supports 3S (11.1V) charging. The battery features a balance connector that allows you to monitor and balance individual cell voltages during charging, which is essential for LiPo battery health and safety. Most modern RC chargers support LiPo charging protocols and balance charging simultaneously.
• Is the hard case worth the extra cost? — Yes, the hard case provides significant advantages over soft-case batteries. It offers protection during transport, prevents accidental punctures or impacts that could damage cells or cause short circuits, and allows you to push your RC vehicle harder without worrying about battery damage. This protection extends battery lifespan and improves safety.
• What is the 50C discharge rate and why does it matter? — The 50C rating indicates the battery can safely discharge at 50 times its capacity continuously. For this 4000mAh battery, that means 200A maximum continuous current. This high discharge capability is essential for brushless RC vehicles that require substantial current, ensuring your battery can keep up with your motor's demands without voltage sag, which would reduce acceleration and top speed.
• How should I store this LiPo battery? — Store the battery in a cool, dry location (ideally 15-25°C) at a safe storage charge of around 3.7V per cell (approximately 50% charge). Never store a fully charged or fully discharged LiPo battery for extended periods. Store in a fireproof container or LiPo bag for added safety, away from flammable materials.
• How does the EC5 connector compare to other connectors like XT90 or XT60? — The EC5 connector is a high-current connector suitable for up to 200A continuous discharge, making it ideal for high-power applications. It provides low resistance and secure connections. Different vehicles use different connectors, so check your RC vehicle's connector type before purchasing to ensure compatibility.
