VOLTZ 3500mAh HARD CASE 11.1V 3S 30C LiPo BATTERY VZ0339

Overview

The Voltz 3500mAh Hard Case 11.1V 3S 30C LiPo Battery (VZ0339) is a premium power solution designed for RC enthusiasts across the UK who demand reliable, durable battery performance. Whether you're running an RC car, truck, or buggy, this hard case LiPo battery delivers the consistent power needed for extended playtime and competitive performance. The Voltz brand has earned a reputation for quality in the RC hobby community, and this 3S battery represents excellent value for money at just £39.99.

This battery is particularly suited for RC car UK hobbyists looking to upgrade their power system or replace a worn battery pack. The hard case construction protects the internal cells from damage during transport and use, making it an ideal choice for both weekend bashers and serious racers. The low profile design means it fits comfortably in most RC vehicle battery bays, saving you the frustration of compatibility issues that plague many off-the-shelf battery solutions.

If you're exploring brushless RC cars or upgrading from a brushed setup, having a quality 3S LiPo battery like this one is essential. The 30C discharge rate ensures you have plenty of power for acceleration and sustained high-speed running, whilst the hard case design means your investment is protected and will last longer than soft-case alternatives commonly available in the RC hobby marketplace.

Key Features

• 3500mAh Capacity — This capacity provides an excellent balance between weight and runtime for most RC applications, giving you extended running time without making your vehicle unnecessarily heavy or unbalanced.
• 11.1V 3S Configuration — The three-cell series arrangement delivers the ideal voltage for most brushless RC motors and electronic speed controllers, ensuring compatibility with the vast majority of modern ready to run RC cars and trucks available in the UK market.
• 30C Continuous Discharge Rate — This rating means the battery can safely deliver 105 amps of continuous current (3500mAh × 30C), providing plenty of power for high-performance driving, rapid acceleration, and sustained speeds without voltage sag.
• Hard Case Protection — The rigid plastic shell safeguards the lithium polymer cells from impacts, punctures, and crushing forces that would damage soft-case batteries, extending the lifespan of your investment and keeping you safe.
• Low Profile Design — At just 25.4mm in height, this battery fits in tight spaces where standard-height batteries won't fit, making it compatible with more RC vehicle models and allowing for better weight distribution in your chassis.
• Deans Connector — The industry-standard T-Plug (Deans) connector is widely recognised and used across RC vehicles, making this battery compatible with the vast majority of ready to run RC cars, buggies, and trucks without requiring adapters.
• Precise Dimensions — Measuring 138.2mm in length, 46.6mm in width, and 25.4mm in height, this battery is designed to fit standard battery bays across FTX models including the Rokatan, Ramraider, and Apache, though you should always verify your specific model's battery bay measurements before purchasing.

Technical Performance

The Voltz 3500mAh 11.1V 3S 30C LiPo Battery represents solid engineering and proven performance in the RC hobby sector. The 30C discharge rate delivers 105 amps of continuous output, which is more than adequate for driving high-performance brushless RC cars and providing the responsive throttle response that racers demand. The 11.1V nominal voltage across three cells (approximately 3.7V per cell when fully charged to 4.2V per cell) is the industry standard for modern ESCs and brushless motors, ensuring you get maximum efficiency and performance from your setup. The hard case construction uses durable ABS plastic designed to withstand the rigours of RC driving, protecting the cells from physical damage that would compromise battery safety and longevity. Unlike soft-case batteries that can be punctured or crushed, the hard case design makes this an excellent choice for serious RC enthusiasts who want peace of mind during transport and storage. The compact 25.4mm height is particularly impressive, as it allows fitting in low-slung race cars and compact chassis designs where taller batteries simply won't fit. With the Deans connector pre-installed, you're ready to use this battery immediately with any compatible RC car or truck, making it an excellent spare battery for maintaining action on the track or bash spot without downtime waiting for batteries to charge.

What's in the Box

What You Need to Complete

• LiPo Charge Sack — A fireproof charging bag is highly recommended for safe charging and storage of your LiPo battery, protecting against potential fire hazards.
• LiPo Charger — You'll need a dedicated LiPo charger (not included) to safely charge this battery; standard wall chargers are unsuitable for lithium polymer batteries and can cause damage or safety issues.
• RC Vehicle Compatible with 3S LiPo — Ensure your RC car, truck, or buggy is equipped with a brushless ESC rated for 3S LiPo operation, typically found on most modern brushless ready to run RC cars available in the UK.

Frequently Asked Questions

• Does the Voltz 3500mAh battery come with a charge sack? — No, the LiPo charge sack is not included and must be purchased separately. This is standard practice across the RC hobby, as most enthusiasts use a dedicated fireproof sack for charging and storing multiple batteries safely.
• What is the 30C rating and why does it matter? — The 30C rating refers to the continuous discharge rate, meaning this 3500mAh battery can safely deliver 105 amps of current continuously. A higher C-rating means more power and less voltage sag during high-speed driving, making it ideal for brushless RC cars and competitive racing applications.
• Will this battery fit my RC car? — The Voltz VZ0339 is designed to fit standard battery bays and is confirmed compatible with FTX models including the Rokatan, Ramraider, and Apache. However, you should verify your specific vehicle's battery bay dimensions (ideally at least 140mm length, 50mm width, and 30mm height) before purchasing to ensure proper fitment.
• Is this suitable for beginners? — Whilst technically suitable for beginners, LiPo batteries require more careful handling than NiMH batteries and must be charged with a proper LiPo charger and stored in a fireproof sack. If you're new to RC, you may want to start with NiMH or learn proper LiPo safety practices first.
• What type of RC vehicles can use this battery? — This 3S LiPo is ideal for brushless RC cars, buggies, trucks, and other vehicles with compatible brushless ESC controllers. It's particularly well-suited for ready to run RC cars available in the UK market that specify 3S LiPo compatibility.
• How long will this battery last per charge? — Runtime depends on your specific vehicle's motor, driving style, and terrain. Generally, a 3500mAh battery provides 20-40 minutes of active driving on a single charge for most RC cars, though this varies significantly based on your setup and usage.
• Can I use this battery with my existing charger? — Only if your charger is specifically designed for 3S LiPo batteries and features a balance connector. Standard wall chargers and older NiMH chargers are not suitable and can damage the battery or create safety hazards.
