This capacity is perfectly matched to compact RC platforms where space is at a premium, ensuring you get meaningful runtime without requiring a battery that's too large for your vehicle's chassis.
• 30C Continuous Discharge Rate — The 30C rating means this battery can safely deliver 24 amps of continuous current (800mAh × 30C = 24A), making it suitable for high-performance applications including racing, aggressive bashing and competitive driving. This substantial discharge capability ensures your RC vehicle maintains full power even under demanding throttle conditions.
• Deans (HCT) Connector — The Deans connector is the gold standard in the RC hobby, recognised across the UK and worldwide for its secure connection, low resistance and reliability. This connector type ensures optimal power transfer from battery to vehicle electronics whilst resisting accidental disconnection during aggressive driving or crashes.
• Compact 73 x 26 x 18 mm Dimensions — The space-conscious footprint of just 73mm length, 26mm width and 18mm height makes this battery compatible with most modern RC car designs where battery bay space is limited. The compact form factor is particularly valuable for mid-sized buggies and trucker-style RC vehicles where weight distribution and chassis balance are critical to performance.
• Soft Case Protection — The soft case construction provides essential protection against physical damage, short circuits and punctures whilst minimising added weight. The protective case ensures your battery remains in perfect condition through multiple charge cycles and storage periods, extending the lifespan of your investment.
• 11.1V Nominal Voltage — Operating at a nominal 11.1 volts, this battery is compatible with the vast majority of 3S-compatible RC electronics including brushless motors, speed controllers and receivers currently available in the UK RC market. The voltage output remains stable throughout the discharge cycle, providing consistent performance from first acceleration to the final run.

Technical Performance

The Radient LiPo 3S 800mAh 11.1V 30C Deans (HCT) battery represents a well-engineered balance of performance characteristics tailored to the needs of serious RC enthusiasts. The 30C discharge rating delivers substantial current capacity — at 800mAh capacity, this translates to a maximum continuous output of 24 amps, more than adequate for brushless motor systems, ESCs rated for 30A and above, and competitive driving scenarios where sustained high current draw is essential. The three-cell lithium polymer chemistry ensures consistent voltage delivery across the entire discharge cycle, meaning your RC vehicle maintains predictable acceleration, handling and power characteristics from the moment you press the throttle until the battery approaches depletion. The lightweight construction, with a shipping weight of just 0.08 kilograms, ensures minimal impact on your RC vehicle's weight distribution and agility. The 11.1V nominal output makes this battery immediately compatible with virtually all 3S-ready RC platforms currently available, from entry-level ready-to-run kits to competition-grade custom builds. The soft case housing protects internal cells from physical damage during transport, storage and field use, whilst the Deans connector interface ensures reliable, low-resistance power delivery to your speed controller and motor system. Whether you're running this battery in a lightweight 1/10 scale RC buggy, a nimble RC crawler tackling technical terrain, or any other 3S-compatible electric RC model, the Radient delivers the consistent, dependable performance that serious hobbyists expect from their equipment.

Frequently Asked Questions

• What RC vehicles is the Radient 3S 800mAh battery compatible with? — This 3S 11.1V battery is compatible with any electric RC vehicle designed to accept 3S LiPo batteries with a Deans connector, including most 1/10 scale RC buggies, RC crawlers, RC trugs, RC short-course trucks and lightweight 1/8 scale applications. Always verify your RC model's manual to confirm 3S compatibility before purchasing. The compact dimensions make it especially suitable for modern platform designs where battery space is limited.
• Is this battery suitable for beginners? — Yes, whilst the 30C discharge rating makes this battery capable of high performance, it is suitable for users aged 14 and above with proper supervision and care. However, beginners should understand LiPo battery safety protocols including proper charging with a balance charger, safe storage in a fireproof bag, and immediate inspection for damage before each use. If you are entirely new to the RC hobby, we recommend seeking guidance from experienced RC enthusiasts or visiting our Walsall store for hands-on advice.
• What charger do I need for this battery? — You will need a dedicated LiPo balance charger capable of charging 3S lithium polymer batteries. The charger must support 3-cell balance charging to ensure each cell charges evenly and safely. Charging current should not exceed 2.4A (which is 3C for this 800mAh pack), and we recommend 1.2A charging current for optimal battery longevity. A quality balance charger is essential for safe operation and extends the lifespan of your battery significantly.
• How long will this battery last on a single charge? — Runtime depends on your specific RC vehicle's weight, motor size, driving style and terrain. Generally, an 800mAh pack will provide 10-20 minutes of active driving, with lighter vehicles and smooth terrain offering longer runtimes than heavy vehicles or aggressive bashing. Most RC enthusiasts carry multiple batteries to extend their driving session duration.
• What does the 30C rating mean? — The 30C rating indicates the maximum continuous discharge rate as a multiplier of the battery's capacity. At 800mAh capacity, a 30C rating allows continuous discharge of 24 amps (800mAh × 30 = 24A). This substantial current capability makes the battery suitable for high-performance brushless motor systems and competitive driving scenarios where consistent high power output is essential.
• How should I store this battery? — LiPo batteries should be stored in a cool, dry location at approximately 50% charge state for extended storage periods. Store the battery in a fireproof LiPo bag or metal container away from flammable materials. Check the battery monthly and top up the charge if voltage drops below recommended levels. Proper storage prevents damage, extends battery life and maintains safety.
• Is the Deans connector standard for UK RC vehicles? — Yes, the Deans (HCT) connector is the industry-standard high-current connector used across virtually all serious RC vehicles in the UK and internationally. It provides secure connections, low electrical resistance and excellent reliability compared to older XT60 or Dean's alternatives. Most quality RC speed controllers and receiver batteries feature Deans connectors as standard.
