Radient LiPo Battery 2S 450mAh 7.4V 30C JST Connector RDNB4502S30JST

Overview

The Radient LiPo 2S 450mAh 7.4V 30C JST battery is a compact and lightweight lithium polymer power pack designed for RC hobbyists who need reliable performance in a space-conscious package. Weighing just 30 grams and measuring a mere 61 x 30 x 10 mm, this battery is engineered to fit into tight battery bays where conventional larger packs simply won't fit. Whether you're flying a lightweight RC drone, powering a compact RC car UK setup, or running a miniature RC vehicle that demands minimal weight, this Radient battery delivers straightforward, dependable energy storage with convenient JST connector compatibility.

For those exploring the world of RC hobby solutions in the UK, this 2S LiPo pack represents an excellent choice for replacement batteries or spares. The 450mAh capacity provides meaningful flight or run time despite the compact dimensions, whilst the 30C discharge rating ensures sufficient power delivery for dynamic performance. This is not a battery for heavy-duty bashers or high-power racing applications—instead, it excels in lightweight installations where every gram matters and space is at a premium. RC enthusiasts shopping for ready to run RC models with modest power requirements, or those building custom lightweight setups, will appreciate both the practical form factor and the honest performance this pack delivers.

With clear labelling printed directly on the soft case and a professional appearance, the Radient LiPo 2S 450mAh battery makes an obvious practical choice for RC builders and pilots who understand the importance of appropriate power matching. The JST connector is industry-standard, ensuring compatibility with a wide range of RC equipment without the need for adapter cables. At RC Model Shop, we stock this battery as part of our comprehensive range of Radient power solutions, supporting both beginners learning the fundamentals of LiPo battery management and experienced RC users maintaining spares for multiple aircraft or vehicles.

Key Features

• Ultra-compact dimensions — At just 61 x 30 x 10 mm in size, this battery is engineered to fit into space-constrained battery bays where larger packs cannot be accommodated, making it ideal for lightweight RC aircraft, micro RC cars, and custom-built compact setups.
• Minimal weight penalty — Weighing only 30 grams, this pack maintains your RC model's weight budget whilst still delivering usable capacity, which is crucial for optimising flight time, acceleration and overall handling characteristics in lightweight applications.
• 2S voltage configuration — The 7.4V output from this dual-cell LiPo pack is perfectly matched to electric motors and ESCs designed for 2S power, providing balanced performance without overstressing components engineered for this voltage.
• 30C continuous discharge rating — This respectable C-rating means the battery can deliver 13.5 amps of continuous current, providing adequate power for recreational flying and driving without thermal stress, though it is not designed for extreme racing or peak-current applications.
• JST connector compatibility — The standard JST plug connects directly to most RC receivers, flight controllers and ESCs without requiring proprietary adapters, simplifying setup and reducing connection points where failures might occur.
• Soft case construction — The protective soft case safeguards the cells from physical damage during storage and transport whilst remaining lightweight, and the clear labelling ensures you always know this pack's voltage and capacity at a glance.
• Genuine Radient quality — Manufactured by Radient, a recognised name in LiPo battery production, this pack benefits from quality control and consistent performance standards expected from an established RC power supplier.

Technical Performance

The Radient LiPo 2S 450mAh 7.4V 30C battery represents a thoughtfully engineered balance between capacity and physical constraints. With a nominal voltage of 7.4 volts across two lithium polymer cells in series, it delivers the standard 2S power profile that matches hundreds of micro and lightweight RC electric motors, small brushless outrunners, and entry-level ESC units currently available in the UK RC market. The 450mAh capacity, whilst modest in absolute terms, translates to meaningful runtime in lightweight applications: for example, a 450mAh capacity powering a 4.5-amp draw would provide approximately 6 minutes of continuous operation, though actual runtime varies significantly based on load profile, altitude, terrain and flying or driving style. The 30C discharge rating, calculated as 450mAh × 30 = 13.5 amps maximum continuous current, sits comfortably within the safe operating envelope for this battery size, allowing sustained power delivery without thermal runaway or voltage sag that would compromise performance. The engineering choice to implement soft case protection rather than rigid hard case keeps the package weight minimal whilst still offering meaningful mechanical protection during handling, storage and transport. The JST connector uses proven crimped contact technology, creating reliable electrical connections that exhibit low resistance and consequently minimal voltage drop—a critical factor in maximising the available power delivery to your RC equipment. For users building custom RC vehicles or aircraft, or those maintaining spares for multiple machines, this battery's consistent performance, straightforward specification and compact footprint make it a reliable workhorse solution that won't let you down during weekend flying or driving sessions.

Frequently Asked Questions

• Is this battery suitable for RC drones and multirotors? — Yes, this 2S 450mAh pack is well-suited to lightweight RC drones and small quadcopters designed for 7.4V power. The compact dimensions and 30-gram weight make it ideal for micro and lightweight aerial platforms where space and weight are critical design constraints.
• What RC cars, trucks or buggies can use this 2S LiPo battery? — This battery works with any 2S-compatible RC car, truck, buggy or crawler equipped with a 7.4V-rated ESC and JST connector. Typical applications include micro scale RC vehicles, lightweight bashers, and compact custom-built setups where a full-size battery would be inappropriate.
• How long does the battery last on a single charge? — Runtime depends entirely on your RC equipment's power consumption. As a rule of thumb, a vehicle or aircraft drawing 4.5 amps would run for approximately 6 minutes, whilst a lower-power 2-amp draw could extend runtime to around 12–15 minutes. Always check your equipment's current draw specifications for accurate predictions.
• Is the JST connector standard? — Yes, the JST connector is an industry-standard plug type widely used throughout RC hobby equipment. This means you can connect directly to most ESCs, flight controllers and battery management systems without requiring adapters, though always verify your equipment supports JST connectors.
• Can I use this with 3S or 4S equipment? — No, this is a 2S pack delivering 7.4V nominal voltage. Connecting it to equipment designed for 3S or 4S LiPo batteries (which expect 11.1V or 14.8V respectively) will result in severe under-voltage performance and potential equipment damage. Always match battery voltage to your ESC's specifications.
• What is the difference between 450mAh and larger capacity batteries? — The 450mAh capacity in this pack is intentionally conservative, keeping weight and size minimal for applications where those factors are paramount. Larger capacity batteries (such as 1300mAh or 2200mAh packs) offer extended runtime but at the cost of increased weight and volume, making them unsuitable for lightweight installations.
• Is this battery safe for beginners to use? — Yes, this battery is suitable for RC hobbyists of all experience levels including beginners. At just 30 grams with conservative capacity, it poses minimal safety risk during normal use. That said, all LiPo batteries require proper charging using a LiPo-compatible charger with cell balancing capability—never use standard NiMH chargers on lithium polymer packs.
• What charger do I need for this battery? — You will need a LiPo-compatible charger with 2S balance charging capability. The JST connector accepts standard charging leads. Do not attempt to charge this battery with conventional NiMH or lead-acid chargers, as this will damage the cells and create a serious fire hazard.
