Key Features

• 1600mAh Capacity — This capacity offers a practical sweet spot for compact RC models, delivering sufficient runtime for recreational flying or driving sessions without excessive weight penalties that would compromise acceleration and manoeuvrability.
• 30C Discharge Rate — The 30C continuous discharge capability means this battery can safely deliver up to 48 amps of current (30 x 1.6Ah), making it suitable for high-performance motors and demanding RC applications whilst maintaining cell safety and lifespan.
• 3S LiPo Chemistry (11.1V) — Three lithium polymer cells in series deliver 11.1V nominal voltage, the industry standard for mid-range electric RC cars, boats and aircraft, ensuring compatibility with the vast majority of modern RC equipment available in the UK market.
• EC3 Connector — This widely-used connector type is found on countless modern RC models, ESCs and chargers, making the Radient battery highly versatile and reducing the need for expensive adapter cables or modifications.
• Compact Dimensions (86 x 36 x 24mm) — The small footprint allows installation in tight battery compartments where standard larger packs simply won't fit, making this battery ideal for micro-scale RC models and space-constrained designs.
• Soft Case Protection — The integrated soft case provides essential protection against physical damage during storage and transport, protecting the delicate lithium cells from punctures and crushing whilst remaining flexible and lightweight.
• Lightweight Construction — Weighing just 140 grams, this battery is engineered for applications where weight matters, whether you're maximising flight time on a drone or improving acceleration in a lightweight RC car.

Technical Performance

This Radient LiPo 3S battery pack represents solid engineering in a compact form factor. The 30C discharge rating indicates the battery can safely deliver high currents without excessive voltage sag or heat generation, a critical consideration for RC applications where motor performance is paramount. The lithium polymer chemistry used in modern LiPo batteries like this one offers significantly superior energy density compared to older NiMH technology, meaning lighter weight and more power from the same footprint. The 11.1V nominal voltage across the three 3.7V cells provides the optimal power delivery window for brushless motors in the 3000-5000KV range commonly found in compact RC models. Construction quality is paramount with LiPo batteries, and Radient batteries are manufactured to strict safety standards with internal protection against over-discharge and cell imbalance. The EC3 connector uses gold-plated contacts to minimise connection resistance and voltage drop during high-current discharge, critical for maximising the available power from the pack. The soft case uses specialised materials that expand slightly with cell swelling, a natural occurrence in lithium batteries, preventing rupture or failure. This battery is suitable for users aged 14 and over, and proper handling and storage procedures should always be followed to ensure safety and longevity. When stored correctly between usage, LiPo batteries can maintain performance for dozens of charge cycles, making this an economical choice for regular RC enthusiasts.

Frequently Asked Questions

• What RC models is this 3S LiPo battery compatible with? — This battery is designed for any RC model that accepts a 3S LiPo battery with an EC3 connector and approximately 86 x 36 x 24mm dimensions. This includes many compact RC cars, lightweight RC boats, FPV racing drones and micro-scale RC aircraft. Check your model's battery compartment dimensions and connector type before purchasing to ensure compatibility. The EC3 connector is standard across a huge range of ready to run RC models available in the UK, making this a highly compatible choice.
• Is the Radient LiPo 3S 1600mAh suitable for beginners? — Yes, this battery is suitable for beginners aged 14 and over. The 1600mAh capacity and 30C discharge rate provide safe, manageable power delivery without the extreme performance demands of race-orientated packs. However, beginners must understand proper LiPo handling, storage and charging procedures. LiPo batteries require a dedicated LiPo charger and should never be left unattended whilst charging. The battery should be stored in a cool, dry location at approximately 50% charge state between usage sessions.
• What charger do I need for this battery? — You will need a dedicated LiPo-compatible charger capable of balanced charging. Most modern RC chargers, whether budget-friendly entry-level models or advanced multi-chemistry units, support LiPo battery charging. Set your charger to 3S LiPo mode, and charge at 1-2C rate (1.6-3.2 amps) for optimal battery lifespan. Never use old NiMH chargers with LiPo batteries as they will cause cell damage and safety hazards.
• How long will this battery power my RC model? — Runtime depends entirely on your model's power draw and motor type. A lightweight RC car with an efficient brushless motor might achieve 15-20 minutes of continuous running, whilst a high-power racing vehicle could deplete it in 8-10 minutes. Typical FPV drones see 12-18 minutes of flight time depending on weight and throttle usage. Check your specific RC model's documentation for typical runtime figures with this capacity battery.
• What does the 30C discharge rating mean? — The 30C rating means the battery can continuously discharge at 30 times its capacity in amps. With a 1600mAh capacity, this translates to 48 amps continuous maximum discharge. This rating ensures the battery can safely power high-performance motors without excessive voltage sag, heat generation or cell damage. Higher C ratings allow faster motor response and more consistent power delivery under load.
• Can I use this battery in my brushless RC car? — Yes, provided your brushless ESC (electronic speed controller) is rated for 3S LiPo operation and the battery dimensions fit your model's battery compartment. Most modern brushless RC cars operate on either 2S or 3S LiPo batteries, with 3S being the standard for mid-range models. Always check your ESC's voltage rating (it should state 3S or 11.1V compatibility) and your RC car's battery bay dimensions before purchasing.
• What is the difference between this 30C battery and a higher 50C or 100C LiPo? — The C rating indicates maximum safe discharge current. A 50C or 100C battery can deliver higher currents without damage, but this comes with increased cost and often slightly heavier weight. For recreational RC use, the 30C rating is perfectly adequate and provides excellent value for money. You would only need a higher C rating for competitive racing or extreme performance applications demanding absolute maximum motor response.
