Technical Performance

The Radient LiPo 3S 2700mAh 11.1V 30C battery represents a well-engineered power solution that has been proven across countless RC applications. The 30C discharge rating indicates robust internal construction using quality lithium polymer cells, capable of delivering sustained high current without overheating or voltage sag that would compromise your model's acceleration and top speed. The 11.1V nominal voltage (3.7V per cell × 3 cells) is the industry standard for 3S LiPo configurations and is compatible with virtually all modern brushless ESCs rated for 3S input, as well as many brushed speed controllers. The 2700mAh capacity, when discharged at the 30C rate, provides approximately 81 amps of maximum continuous output, sufficient for high-performance RC cars, trucks, and other electric RC models in the UK market. The total energy storage of 29.97 watt-hours (11.1V × 2.7Ah) delivers practical runtime typically ranging from 15 to 25 minutes depending on driving style, terrain, and vehicle weight—ideal for multiple back-to-back runs at your local RC track or off-road spot. The soft case construction utilises durable, flame-resistant materials that protect the delicate lithium polymer cells from physical impact and provide thermal insulation, whilst the Deans connector's low-resistance design and secure fit eliminate power loss at the connection point, critical for maintaining voltage stability under load.

Frequently Asked Questions

• Is the Radient 3S 2700mAh LiPo battery suitable for beginners in the RC hobby? — Yes, absolutely. This battery is an excellent choice for beginners because the 3S voltage configuration is widely supported across entry-level and intermediate RC vehicles, the 2700mAh capacity provides practical runtime for learning sessions, and the 30C discharge rating ensures the battery won't limit performance even if your vehicle is capable of high speed. The age recommendation of 14+ reflects safe handling practices for lithium polymer batteries, and the battery's compact size makes it easy to store and transport. We recommend pairing it with a quality balance charger and learning proper LiPo care practices before your first charge.
• What RC vehicles is this battery compatible with? — The Radient 3S 2700mAh 11.1V 30C battery is compatible with any RC vehicle designed for 3S LiPo batteries with a Deans connector, including touring cars, short-course trucks, buggies, crawlers, and various aerial platforms. However, you must verify that your specific model's battery tray matches the dimensions (135mm × 42mm × 18mm) and that your ESC and receiver support 3S LiPo input before purchasing. Always check your vehicle's manual for battery compatibility specifications.
• How long will this battery last per charge? — Typical runtime ranges from 15 to 25 minutes of continuous use, depending on driving style, terrain, vehicle weight, and motor efficiency. Aggressive driving with frequent maximum throttle will reduce runtime, whilst smooth, controlled driving will extend it. Most RC hobbyists purchase multiple batteries to rotate through charge cycles, allowing multiple sessions in a single outing without lengthy charging waits.
• Can I use this battery with my brushed motor RC car? — Yes, provided your brushed ESC is rated for 3S LiPo input. Many brushed speed controllers support 2S or 3S LiPo directly, but always verify your ESC's specifications before connecting this battery. Never attempt to use a battery with an ESC not designed for its voltage, as this can cause damage to the speed controller.
• What is the difference between the Radient 3S 2700mAh and other 3S batteries? — The key differentiators are capacity (2700mAh offers mid-range runtime and weight), discharge rating (30C provides adequate power for most recreational RC vehicles), and build quality (Radient uses consistent cell matching and reliable manufacturing). Some batteries offer higher discharge rates (50C, 100C) for extreme performance at the cost of increased weight, whilst others offer larger capacities (5000mAh+) for extended runtime at the cost of increased bulk and weight. The Radient 2700mAh 30C represents an excellent balance for general-purpose RC use.
• How should I charge and care for this LiPo battery? — Always use a balance charger specifically designed for LiPo batteries, never use standard NiMH chargers. Charge at 1C rate (2.7 amps for this battery) for normal use, or up to 2C (5.4 amps) if your charger supports it. Always balance the cell voltages using the balance port. Store the battery in a fireproof LiPo bag at room temperature with cells at approximately 3.8V per cell (11.4V total) between uses. Never fully discharge below 3.0V per cell. Inspect the battery regularly for damage, puffing, or leaks before each use.
• Is this battery waterproof for use in water-based RC models? — No, this is a standard LiPo battery and is not waterproof. Whilst some RC vehicles are waterproof, the battery itself should never be exposed to water. If using this battery in a waterproof RC vehicle that may encounter water, ensure the battery compartment is properly sealed and consider using a waterproof battery case.
