Key Features
- 7.4V 2S LiPo Chemistry — This battery comprises two cells in series, delivering 7.4V nominal voltage (8.4V when fully charged), making it ideal for small electric motors found in RC aircraft and helicopters. The 2S configuration strikes a perfect balance between power output and weight, critical for maintaining proper flight balance and performance.
- 200mAh Capacity — The 200mAh energy storage capacity is specifically matched to small-scale RC aircraft, providing adequate flight time without adding excess weight that could affect your model's flying characteristics, climb rate, or aerodynamic efficiency.
- 30C Discharge Rating — The 30C continuous discharge rating means this battery can safely deliver 6 amps of current (200mAh × 30C = 6A) continuously, providing the power necessary for brushless motors in small RC planes and helicopters without risk of over-stress or dangerous voltage sag during peak power demands.
- PH Connector — This battery features the PH connector, E-flite's standard connection type used across their aircraft and receiver systems. The PH connector ensures a secure, polarised fit that prevents accidental reverse polarity connections which could damage your aircraft's electronics.
- Genuine E-flite Manufacturing — Built by E-flite, a subsidiary of Horizon Hobby, this battery meets strict quality control standards and safety certifications. You're purchasing genuine aerospace-grade LiPo technology, not aftermarket alternatives or budget copies.
- Lightweight Design — At 4.5 watt-hours total energy, this battery weighs significantly less than comparable alkaline or NiMH alternatives, making it the preferred choice for any RC aircraft application where minimising weight is essential for optimal flight performance.
- Reliable Voltage Stability — LiPo chemistry delivers consistent voltage output throughout the discharge cycle, meaning your RC aircraft maintains responsive throttle control and consistent motor performance from first flight until battery depletion, unlike older battery types that fade gradually.
Technical Performance
This E-flite LiPo battery represents the pinnacle of modern RC aircraft power technology. The 7.4V nominal output (3.7V per cell) is engineered specifically for brushless outrunner motors commonly found in modern electric RC aircraft, providing the voltage sweet spot that balances thrust, efficiency, and flight duration. The 30C continuous discharge rating ensures stable current delivery even under full throttle conditions, preventing the voltage sag that could compromise your aircraft's climb performance or make it feel sluggish during aerobatic manoeuvres. With 4.5 watt-hours of total energy capacity, this battery delivers approximately 10-15 minutes of moderate-intensity flight time depending on your specific aircraft's motor, propeller configuration, and flying style. The construction utilises premium lithium polymer chemistry with internal cell balancing to ensure each of the two cells charges and discharges evenly, extending cycle life and maintaining safety throughout the battery's service life. The PH connector is gold-plated to ensure minimal contact resistance and reliable power transfer with zero voltage drop. This battery integrates seamlessly with genuine E-flite aircraft designs, Spektrum receiver systems available in the UK, and any RC helicopter or aircraft equipped with PH-compatible connectors. For pilots building custom RC aircraft or selecting batteries for compatible models, this represents a trusted, proven power source used by recreational pilots and serious enthusiasts alike.
What's in the Box
- E-flite 7.4V 200mAh 2S 30C LiPo Battery with PH Connector
What You Need to Complete
- LiPo-Compatible Battery Charger — You must use a charger specifically designed for LiPo batteries with a balance charging function to safely and correctly charge this battery. Standard alkaline or NiMH chargers will not work and may damage the battery or create a safety hazard.
- LiPo Charging Bag — A fire-resistant LiPo charging bag is essential safety equipment, protecting your home and charging equipment in the extremely unlikely event of a cell failure during the charging process.
Frequently Asked Questions
- What aircraft and helicopters can use this E-flite 7.4V 2S LiPo battery? — This battery is compatible with any RC aircraft or helicopter equipped with a PH connector and designed to accept 2S LiPo batteries. Typical applications include E-flite trainer aircraft, micro helicopters, small park flyers, and compatible brushless aircraft from other manufacturers. Always verify your specific aircraft's compatibility before purchasing by checking the instruction manual or manufacturer specifications.
- How long will this 200mAh battery keep my RC aircraft flying? — Flight time depends entirely on your aircraft's motor size, propeller configuration, and flying style. As a general rule, expect 10-15 minutes of moderate flying before the battery requires recharging. Gentle, level flight extends duration; aggressive aerobatics or high-throttle flying reduces it. Many pilots purchase multiple batteries to extend their flying session without waiting for recharge time.
- Is this suitable for beginner RC aircraft pilots? — Absolutely. The 7.4V 2S format is the standard power source for beginner-friendly E-flite trainer aircraft and small RC helicopters. The 200mAh capacity is perfectly matched to these platforms, providing adequate power without overwhelming a new pilot. However, you must invest in a proper LiPo charger and charging bag—these are not optional accessories but essential equipment for safe operation.
- What is the difference between this 30C battery and other E-flite LiPo options? — The 30C rating means this battery is optimised for steady, moderate power applications. E-flite offers higher-capacity batteries (larger mAh ratings) for longer flight time, and different C-ratings for different power demands. The 200mAh, 30C combination is specifically designed for small, lightweight aircraft where minimising weight is paramount and consistent moderate power is more important than maximum peak current.
- Do I need to use an E-flite charger with this battery, or can I use any LiPo charger? — Any genuine LiPo-compatible balance charger will safely charge this battery, provided it supports 2S LiPo chemistry and has a balance charging function. That said, E-flite chargers are specifically engineered to work seamlessly with E-flite batteries and offer the advantage of foolproof compatibility without confusion about settings or protocols.
- How should I store this battery when not in use? — LiPo batteries should be stored at "storage voltage," which is approximately 3.85V per cell (7.7V for a 2S pack). Store the battery in a cool, dry location away from direct sunlight and extreme temperatures. Always keep the battery in a fire-resistant LiPo storage bag. This practice significantly extends the lifespan of the battery and ensures it remains in optimal condition for your next flying session.
