Key Features

• 7.4V 2S Li-Ion Chemistry — This two-cell lithium-ion configuration delivers a nominal voltage of 7.4 volts, providing consistent power output that remains stable throughout the discharge cycle, which is crucial for maintaining predictable RC vehicle performance during extended driving sessions.
• 1200mAh Capacity — The 1200 milliamp-hour capacity offers an excellent balance between weight and runtime, allowing you to enjoy extended driving sessions without sacrificing the agility and responsiveness that RC drivers demand from their vehicles.
• T Plug Connector — The standard T Plug connector ensures broad compatibility across numerous RC models and manufacturers, making this battery a versatile solution for drivers with multiple RC vehicles or those looking to future-proof their battery investment.
• Reliable Li-Ion Technology — Lithium-ion cells provide superior performance characteristics compared to older battery chemistries, including better energy density, reduced memory effect, and improved cycle life, meaning you'll get more charges and longer overall battery lifespan.
• Compact Design — The 18650-format cells deliver substantial power in a form factor that fits easily into most modern RC vehicle chassis designs, maintaining proper weight distribution and handling characteristics.
• Ideal for Mid-Range RC Models — Perfectly suited for 1/10 scale RC vehicles and similar-sized RC models, this battery pack provides the right amount of power without being oversized or undersized for common hobby-grade RC platforms.

Technical Performance

The UDI RC Li-Ion Battery 7.4V 1200mAh delivers impressive technical specifications that make it suitable for a wide variety of RC applications across the United Kingdom. The lithium-ion chemistry provides consistent voltage output throughout the discharge cycle, which is fundamentally different from older battery technologies that experience voltage sag as they deplete. This means your RC vehicle will maintain excellent throttle response and acceleration characteristics from the moment you start driving until the battery reaches very low charge levels. The 7.4V configuration (two cells in series) is ideally matched to many modern brushed and brushless motor systems used in contemporary RC vehicles, from small-scale crawlers to mid-sized RC monster trucks and buggies. The 1200mAh capacity provides sufficient runtime for recreational driving sessions whilst maintaining a weight distribution that optimises vehicle handling. Unlike heavier battery packs that can shift the centre of gravity and negatively impact cornering performance, this sensibly-sized power pack integrates seamlessly into RC chassis designs. The T Plug connector has become increasingly standardised across quality RC manufacturers, ensuring you're investing in a battery pack with genuine long-term versatility across multiple RC platforms. When paired with an appropriate charger system (such as a dedicated 2S-3S Li-Ion charger), this battery will maintain its capacity over dozens of charge cycles, representing excellent value for committed RC hobbyists who expect their equipment to deliver consistent performance over extended periods.

What's in the Box

• One UDI RC Li-Ion Battery 7.4V 1200mAh with T Plug connector

What You Need to Complete

• A compatible Li-Ion battery charger rated for 2S batteries (such as the UDIRC Charger for 2S-3S batteries, part number B3001) to safely charge your battery before each use

Frequently Asked Questions

• Is the UDI RC 7.4V 1200mAh Li-Ion battery suitable for beginners? — Yes, absolutely. Li-Ion batteries are actually ideal for newcomers to the RC hobby because they deliver consistent, predictable power that helps beginners develop smooth throttle control and understand vehicle dynamics. The 1200mAh capacity is modest enough that it won't cause overly aggressive acceleration, making it forgiving for learning purposes, yet substantial enough to provide satisfying runtime and performance once you've gained confidence.
• What charger do I need for this 7.4V Li-Ion battery? — You'll need a charger specifically designed for Li-Ion or lithium-based batteries that supports 2S configuration. The UDIRC Charger (part number B3001) is purpose-designed for 2S-3S batteries and is an excellent choice for safely charging this pack. Never attempt to charge lithium batteries using chargers designed for older NiMh chemistry, as this can damage the battery or create safety hazards.
• How long will this battery last per charge? — Runtime depends on your specific RC vehicle's current draw, motor efficiency, and driving style. Generally, a 1200mAh pack in a small-to-medium RC vehicle like the UDI 1611 will provide 15-30 minutes of driving before you'll notice performance decline, though hard driving draws power faster than relaxed cruising.
• What makes Li-Ion batteries better than the older NiMh batteries I used to use? — Li-Ion technology offers several advantages: they maintain consistent voltage throughout the discharge cycle (so your RC vehicle performs the same at the start and end of the run), they have virtually no memory effect (meaning you can charge them at any state of charge without degrading capacity), and they provide higher energy density so you get more power in less weight. The trade-off is that they require proper chargers and slightly more careful handling, though modern Li-Ion packs are very safe when used correctly.
• Is this battery compatible with my RC vehicle? — This 7.4V T Plug battery is explicitly designed for the UDI RC 1611 and is compatible with many other RC vehicles that accept 7.4V power systems and feature T Plug connectors. Check your vehicle's manual or manufacturer specifications to confirm compatibility before purchasing. If your vehicle uses a different connector type (such as Deans, XT-60, or proprietary plugs), you'll need either an adapter or a battery pack with the correct connector.
• How often can I recharge this battery? — Quality Li-Ion cells like those used in this UDIRC pack typically support 500+ charge cycles before capacity noticeably decreases. With proper care and using an appropriate charger, you can realistically expect 1-2 years of regular use from this battery pack before replacement becomes necessary, making it an economical choice for committed RC enthusiasts.
• Can I leave this battery sitting unused for long periods? — Li-Ion batteries perform best when stored at partial charge (around 50-70% capacity) in a cool location rather than fully charged or fully depleted. If you plan to store your battery for more than a few weeks, charge it to about halfway, then store in a cool, dry place away from direct sunlight. This approach maximises long-term battery life.
