Key Features
- 1350mAh Capacity — The 1350 milliamp-hour rating provides sufficient energy storage to deliver respectable flight times for small to medium-sized electric RC aircraft, quadcopters and helicopters whilst remaining light enough to maximise lift and manoeuvrability without excessive weight loading on your model's airframe.
- 11.1V 3S Configuration — Three lithium polymer cells in series deliver 11.1 volts nominal (3.7V per cell), which is the recognised standard voltage for countless RC motor and ESC combinations, ensuring seamless compatibility with your existing equipment without requiring voltage regulators or converters.
- 30C Continuous Discharge Rate — The 30C rating indicates this battery can safely deliver thirty times its capacity in amperage continuously, meaning a 1350mAh pack supplies up to 40.5A of sustained current without thermal damage or performance loss—essential for maintaining consistent power during demanding flight sequences or aggressive aerobatic manoeuvres.
- 40.5A Maximum Continuous Discharge Current — The carefully engineered maximum continuous discharge current specification ensures the battery can supply peak power demands whilst remaining within safe operating parameters, protecting both the battery cells and your connected electronics from excessive current stress that could cause premature failure.
- EC3 Connector — The EC3 connector standard is widely recognised across the RC hobby community and offers reliable gold-plated contacts that maintain consistent electrical connection, reducing voltage drop and ensuring efficient power transfer to your motor and ESC without the need for adapter cables.
- 13 AWG Wire Gauge — The substantial 13 AWG copper wiring is thicker and more robust than many competitive alternatives, enabling efficient current flow and minimising resistance heating during high-demand flight operations, which translates to cooler battery operation and extended service life.
- Compact Dimensions — Measuring just 2.7 inches (68mm) in length, 1.4 inches (34mm) in width and 0.9 inches (24mm) in height, this battery pack fits neatly into tight fuselage compartments and battery trays without requiring custom fabrication or frame modifications, making it compatible with countless ready-to-fly and semi-built models available from RC retailers across the UK.
- Lightweight Construction — At just 4.1 ounces (114 grams), the battery adds minimal weight to your RC model, preserving the critical weight-to-power ratio that determines overall flight performance, responsiveness and endurance—particularly important for scale aircraft and high-performance quadcopters where every gram impacts handling characteristics.
Technical Performance
The E-flite 1350mAh 3S 11.1V 30C LiPo battery represents well-engineered power delivery for the electric RC market. The 11.1V nominal voltage (measured as 12.6V fully charged across the three 3.7V cells) sits squarely in the sweet spot for modern brushless motor systems and electronic speed controllers widely available from RC suppliers throughout the United Kingdom. The 30C discharge rating, combined with the calculated maximum continuous discharge of 40.5A, ensures this battery can feed power-hungry brushless motors and high-performance ESCs without thermal runaway or voltage collapse during sustained high-throttle operation. The 15.0 Wh energy content (calculated from 11.1V × 1350mAh) delivers meaningful flight time for compact RC aircraft and quadcopters whilst the hard-case-free design keeps weight to an absolute minimum—critical for models where payload capacity directly impacts performance. The 13 AWG wiring gauge demonstrates attention to electrical engineering detail; thicker conductor wire reduces internal resistance, meaning less energy is wasted as heat during discharge and more usable power reaches your motor. This battery pack has earned recognition as a compatible spare for the Blade 300 X and similar models, indicating proven field performance and real-world reliability. Whether powering a trainer quadcopter, a scale RC helicopter, or a high-performance park flyer, this 3S LiPo delivers the consistent voltage stability and current capacity that separates quality batteries from budget alternatives. The EC3 connector standard means you won't need expensive adapters or risky connector modifications—simply plug into your existing EC3-equipped chargers and aircraft without compromise.

Frequently Asked Questions
- What RC models is the E-flite 1350mAh 3S LiPo compatible with? — This battery is confirmed compatible with the Blade 300 X and any RC model featuring an EC3 connector and capable of accepting 3S LiPo power. That includes countless brushless-equipped quadcopters, RC helicopters, and electric aircraft available from RC retailers across the UK. Always verify your model's battery requirements and connector type before purchasing to ensure perfect compatibility.
- How long will this battery last on a single charge? — Flight time depends on your specific model, motor configuration, weight and flying style. Generally, the 1350mAh capacity in compact RC aircraft delivers 5-15 minutes of flight time, though aggressive flying with constant full throttle will reduce runtime significantly. Conservative, smooth flying extends battery life considerably. Consult your aircraft's manual for manufacturer flight time estimates with comparable battery capacities.
- What charger do I need for this battery? — Any quality LiPo charger equipped with an EC3 connector socket will work perfectly. The 1350mAh capacity charges at standard rates (typically 1-2C charge rates, meaning 1350mA to 2700mA input current). A dedicated RC LiPo charger with 3S awareness ensures proper cell balancing and prevents overcharging, which is essential for battery safety and longevity. RC Model Shop stocks compatible chargers and charging accessories.
- Is this suitable for beginners? — Yes, this battery is appropriate for RC pilots transitioning from ready-to-fly models to more advanced electric systems. However, LiPo batteries require responsible handling, proper charging equipment and safe storage practices. Never leave a LiPo battery unattended whilst charging, always use a dedicated LiPo charger with balance connectors, and store the battery at room temperature in a fireproof container. Beginners should familiarise themselves with LiPo safety protocols before use.
- What does the 30C rating mean? — The 30C rating indicates the maximum continuous discharge rate as a multiple of the battery's capacity. A 1350mAh battery at 30C can safely deliver 1350mAh × 30 = 40.5 amperes continuously without damage. This specification ensures the battery can supply the current demands of high-performance brushless motors and demanding flight styles without voltage sag, overheating or premature failure. Higher C ratings allow more aggressive power delivery; this 30C pack balances performance with cost.
- How does this compare to the Spektrum Smart LiPo alternative? — The E-flite 1350mAh 30C LiPo with EC3 connector offers traditional reliable performance, whilst the Spektrum Smart LiPo 1300mAh 30C alternative features integrated telemetry and smart battery management with an IC3 connector. Both deliver similar performance, though the Spektrum offers advanced diagnostics. Choose based on your preferred connector standard (EC3 versus IC3) and whether you value smart battery features or prefer straightforward, cost-effective operation.
