Overview
The E-flite 70mAh 1S 3.7V 14C LiPo Battery is a compact, high-performance power solution specifically designed for ultra-micro RC models and aircraft. This lightweight battery pack is engineered to deliver reliable, consistent power to some of the smallest and most nimble RC aircraft available in the UK market today. Whether you're flying an ultra-micro glider, a micro quadcopter, or any other small-scale RC aircraft, this battery provides the energy density and discharge rate needed to keep your model airborne and responsive.
At just 70mAh capacity, this battery is perfectly suited for ultra-micro class aircraft where weight is absolutely critical to performance. The compact size and minimal weight mean you can achieve longer flight times by reducing the overall mass your motor needs to lift, making this an ideal choice for RC enthusiasts who want to maximise endurance in their smallest flying machines. The battery's 3.7V nominal voltage is the standard for single-cell lithium polymer packs, providing the efficient power delivery these micro aircraft require.
If you're serious about ultra-micro RC flight in the UK, whether flying indoors in gymnasiums, community halls, or outdoors in parks and gardens, having multiple spare batteries on hand is essential to extend your flying session. The E-flite 70mAh 1S 3.7V 14C LiPo Battery is a must-have spare for any pilot operating ultra-micro models, and purchasing backups ensures you're never grounded when one battery needs charging.
Key Features
- Ultra-Lightweight Design — At just 70mAh, this battery is engineered to be as light as possible whilst maintaining sufficient capacity, which is crucial for ultra-micro aircraft where every gram counts towards flight performance and endurance.
- PH 1.25 Ultra Micro Connector — The Ultra Micro connector type ensures compatibility with a wide range of ultra-micro RC models and aircraft, providing a secure, reliable electrical connection that won't loosen during flight.
- 14C Discharge Rate — The 14C continuous discharge capability means this battery can safely deliver 0.98 amps of current, providing responsive power delivery and ensuring your aircraft has the punch it needs during climbs and aggressive manoeuvres.
- 1S Single Cell Configuration — A single-cell lithium polymer pack simplifies charging, reduces complexity, and keeps the weight down compared to multi-cell batteries, making it ideal for weight-sensitive ultra-micro applications.
- 3.7V Nominal Voltage — The standard 3.7V output of single-cell LiPo batteries is perfectly matched to the specifications of ultra-micro motor and ESC combinations, ensuring optimal performance and efficiency.
- 0.3 Watt Hours Energy Capacity — With 0.3Wh of stored energy, this battery provides sufficient power for extended flights in ultra-micro aircraft when combined with efficient motor systems and intelligent power management during flight.
- Lithium Polymer Chemistry — LiPo technology offers superior energy density compared to older battery chemistries, meaning more power in a smaller, lighter package — essential for ultra-micro RC flight.
Technical Performance
The E-flite 70mAh 1S 3.7V 14C LiPo Battery is engineered with precision to meet the demanding requirements of ultra-micro aircraft and models. The single-cell, single-parallel (1S1P) configuration provides a clean, efficient power delivery system that minimises voltage sag whilst maximising performance. The 14C discharge rating means this battery can continuously supply 0.98 amps of current, which is substantial for micro-scale aircraft and ensures responsive throttle control and adequate power for takeoffs, climbs, and dynamic flight. The PH 1.25 connector, also known as the Ultra Micro connector, has become the industry standard for ultra-micro RC aircraft, and this battery's connector ensures plug-and-play compatibility with the vast majority of modern ultra-micro models. The 3.7V nominal voltage is the characteristic output of single-cell lithium polymer batteries and is optimised for the motor KV ratings and ESC specifications found in ultra-micro aircraft. With a total energy capacity of 0.3 watt-hours (calculated from 70mAh at 3.7V), this battery provides sufficient endurance for extended flights when paired with efficient motor systems. The lightweight construction is absolutely critical for ultra-micro models, where the battery weight directly impacts climb rate, flight time, and overall aircraft performance. Lithium polymer technology ensures consistent voltage output throughout the discharge cycle, meaning your aircraft maintains responsive handling and stable performance until the battery is nearly depleted. This is significantly superior to older nickel-cadmium or nickel-metal hydride batteries, which experience voltage sag as they discharge and can make aircraft handling feel sluggish toward the end of a battery's useful life.
What's in the Box
- 1x E-flite 70mAh 1S 3.7V 14C LiPo Battery with PH 1.25 Ultra Micro Connector
Frequently Asked Questions
- Which ultra-micro aircraft models does this battery fit? — This battery is compatible with any ultra-micro aircraft equipped with a PH 1.25 Ultra Micro connector, which includes models such as the A-EFLU6800 and many other modern ultra-micro RC aircraft from major manufacturers. Always check your aircraft's manual to confirm connector type and recommended battery capacity before purchasing.
- How long will the E-flite 70mAh battery last in flight? — Flight time depends entirely on your aircraft's motor efficiency, flying style, and whether you're using continuous throttle or a mix of powered and unpowered flight (such as in motor gliders). Ultra-micro motor gliders with efficient airframes and folding propellers can achieve 10-20+ minutes of flight time using slightly larger 150-200mAh batteries, so this 70mAh battery will provide somewhat shorter flight times. The best approach is to have multiple batteries available so you can fly back-to-back missions without lengthy wait times between charges.
- What charger does this battery need? — This single-cell LiPo battery requires a charger specifically designed for 1S lithium polymer packs. Spektrum micro USB chargers and other dedicated 1S LiPo chargers are widely available in the UK and are purpose-built for safe, efficient charging of batteries like this one. Never attempt to use a regular power supply or charger designed for other battery chemistries, as this could damage the battery or create a safety hazard.
- Is the E-flite 70mAh battery suitable for beginners? — Yes, absolutely. This battery is designed for ultra-micro aircraft, which are inherently easier to fly and more forgiving than larger models. The simple plug-and-play PH 1.25 connector means charging and battery management is straightforward. However, beginners should familiarise themselves with LiPo battery safety procedures, including proper storage in a LiPo safety bag and regular inspection for any signs of damage or puffing before each flight.
- Can I use this battery in my existing ultra-micro aircraft? — As long as your aircraft has a PH 1.25 Ultra Micro connector and your ESC and motor system are rated for 1S voltage (3.7V), this battery will work perfectly. Check your aircraft's documentation to confirm the recommended battery capacity range and connector type.
- How should I store this battery when not in use? — LiPo batteries should be stored in a cool, dry place, ideally at approximately 50% state of charge. Always keep the battery in a dedicated LiPo safety bag or fireproof container, away from flammable materials. Never store a LiPo battery fully charged or fully depleted, as both conditions reduce long-term cell health.
- What is the difference between this 70mAh battery and larger capacity alternatives? — The 70mAh capacity is designed specifically for the lightest ultra-micro aircraft where minimal weight is essential for optimal performance. Larger batteries like 150mAh or 210mAh packs offer longer flight times but add weight that will reduce climb rate and overall responsiveness in ultra-micro models. Choose the 70mAh battery if you prioritise performance and agility; choose larger capacities if you prioritise flight duration.
