Radient LiPo Battery 2S 800mAh 7.4V 30C Deans Connector RDNB8002S30H

Overview

The Radient LiPo 2S 800mAh 7.4V 30C Deans (HCT) battery is a compact, lightweight power solution engineered for RC enthusiasts who demand reliable performance in space-constrained applications. Whether you're operating a small-scale RC car, truck, or specialist model, this 2S LiPo pack delivers the punch and endurance needed for extended runtime without compromising on weight or size. At just 46 grams, it represents an ideal balance between power delivery and portability, making it an excellent choice for anyone looking to maximise performance in their RC hobby.

Built by Radient, a recognised manufacturer of quality RC batteries, this pack is specifically designed for modellers who understand the importance of proper battery selection. The 30C discharge rate ensures strong acceleration and responsive power delivery, whilst the robust Deans (HCT) connector provides a low-resistance connection that minimises voltage drop during high-demand operations. This is the kind of battery that experienced RC car UK enthusiasts reach for when they need dependable performance without unnecessary bulk or weight penalty.

Small-scale RC models, from nimble racing cars to precision crawlers, often suffer from poor battery bay access and weight distribution challenges. The Radient LiPo 2S 800mAh 7.4V 30C addresses both problems elegantly. Its slim 75 x 25 x 12mm footprint slots neatly into tight battery bays where larger packs simply won't fit, whilst the lightweight construction preserves the handling characteristics and agility your model was designed for. For hobbyists building or upgrading compact RC vehicles, this is a battery that solves real-world problems.

Key Features

• 2S Configuration (7.4V nominal) — The 2-cell series arrangement delivers 7.4 volts at full charge, providing enough voltage for meaningful acceleration and motor responsiveness whilst remaining compatible with a wide range of small-scale RC platforms. This voltage is ideal for compact brushed and brushless motor systems commonly found in miniature RC cars and trucks.
• 800mAh Capacity — The 800 milliamp-hour capacity strikes a careful balance between runtime and weight. You'll achieve practical flight or running times suitable for a complete session, typically between 10 to 20 minutes depending on driving style and motor efficiency, without the weight penalties associated with larger capacity packs.
• 30C Continuous Discharge Rate — The 30C rating means this battery can safely deliver 24 amps of continuous current (800mAh × 30C = 24A), providing robust power for aggressive acceleration, climbing, and high-speed runs. This discharge rate is substantial enough for competitive driving whilst remaining within the safe operating envelope of the cells.
• Deans (HCT) Connector — The Deans connector is recognised throughout the RC hobby as a robust, low-resistance connection standard. Unlike older XT60 or Tamiya connectors, the Deans (HCT) design minimises voltage sag during peak current draw, ensuring your model receives maximum available power without loss due to connector resistance.
• Ultra-Compact 75 x 25 x 12mm Footprint — This slim profile is engineered for tight battery bay installations. Measuring just 75mm long, 25mm wide, and 12mm tall, the pack fits where other batteries cannot, making it essential for compact RC models where space is at an absolute premium.
• Lightweight 46-Gram Construction — Weighing only 46 grams, this battery preserves your model's weight distribution and handling dynamics. For small-scale RC cars and specialist platforms, every gram counts—this pack adds minimal bulk whilst delivering maximum performance.
• Soft Case Protection — The battery arrives in a protective soft case, safeguarding the cells during transport and storage. This padding helps prevent physical damage and extends the lifespan of the pack through careful handling.
• Suitable for Ages 14+ — Radient has rated this battery for users aged 14 and above, reflecting the responsibility required for safe LiPo battery handling, charging, and operation. Younger enthusiasts should use this battery under appropriate adult supervision.

Technical Performance

The Radient LiPo 2S 800mAh 7.4V 30C battery is engineered with genuine lithium polymer cell technology, delivering consistent voltage output and high reliability across thousands of charge cycles. The internal cell configuration uses matched pairs to ensure balanced charge distribution, extending overall pack longevity and maintaining performance consistency throughout the battery's operational life. At 30C continuous discharge, the cells are rated to supply 24 amps without thermal stress, enabling aggressive driving profiles whilst maintaining safe operating temperatures. The Deans (HCT) connector features gold-plated contacts that resist corrosion and provide a secure mechanical fit, eliminating the voltage losses commonly associated with inferior connector designs. For small-scale RC applications—whether you're piloting a nimble 1/18 car, a precision crawler, or a compact truck—this battery's performance envelope encompasses the demanding requirements of modern electric RC vehicles. The 7.4V output is optimised for brushed and brushless motor systems ranging from 3000KV to 15000KV, depending on your motor gearing and transmission setup. Build quality is consistent with Radient's reputation for reliable, competitively priced batteries that deliver genuine performance without premium pricing. The pack's weight-to-power ratio makes it particularly attractive for applications where every fraction of a gram influences acceleration, handling, and power efficiency.

Frequently Asked Questions

• Is the Radient LiPo 2S 800mAh 7.4V 30C suitable for beginners? — Yes, this battery is appropriate for beginners aged 14 and above who understand basic LiPo safety protocols. The compact size and straightforward specifications make it an excellent choice for learning RC hobby basics. However, all LiPo batteries require proper care: charge with a dedicated LiPo charger (not included), monitor for swelling, and store in a cool, dry place. Always verify connector compatibility with your model before use.
• What runtime should I expect from this 800mAh battery? — Runtime depends on your specific motor, gearing, and driving style. Conservative estimates suggest 10 to 20 minutes of continuous operation, though actual performance may vary. Faster motors drawing higher current will deplete the battery more quickly than efficient, carefully tuned setups. Many RC car UK enthusiasts carry multiple charged packs to maximise their session time.
• What models is this battery compatible with? — The Radient LiPo 2S 800mAh 7.4V 30C is suitable for any small-scale RC model with a Deans (HCT) connector, capable of accepting a 7.4V battery pack, and featuring adequate space for the 75 x 25 x 12mm form factor. This includes compact RC cars, trucks, crawlers, and specialist platforms. Always verify dimensional clearance and connector type before purchasing—fitting an incompatible battery can damage your model's electronics.
• Do I need a special charger for this LiPo battery? — Yes, you must use a dedicated LiPo battery charger capable of balancing 2S packs. Standard NiMH or NiCd chargers are unsuitable and dangerous. A proper LiPo charger will charge each cell independently, preventing overcharge and maintaining cell balance. Chargers are available from RC hobby retailers throughout the UK.
• How does the 30C discharge rate compare to other small LiPo packs? — The 30C rating is considered moderate-to-strong for compact batteries in this capacity range. It allows sufficient current delivery for responsive acceleration without thermal stress. Higher discharge rates (50C, 100C) offer more aggressive performance but typically cost more and generate additional heat; the 30C rating represents excellent value for typical RC car applications.
• What is the Deans (HCT) connector, and why does it matter? — The Deans connector is a widely adopted standard in RC hobby applications, featuring a compact male/female design with gold-plated contacts that resist corrosion. The HCT designation indicates a specific variant with enhanced reliability. Unlike older connector types, Deans connectors minimise voltage sag during high current draw, ensuring your model receives maximum available power. They're the professional choice for serious RC enthusiasts.
• Can I use this battery in multiple models? — Absolutely. The Deans (HCT) connector is widely standardised, so this battery will work in any compatible model with the same connector type. This versatility makes it an excellent investment—you can use one battery across different vehicles rather than purchasing dedicated packs for each model.
