Technical Performance
The SPM 2000mAh 2S 7.4V LiPo Receiver Battery represents the culmination of Spektrum's decades of experience in manufacturing radio control systems and components. The battery's engineering focuses on delivering consistent, reliable power to your receiver — arguably the single most critical component in any RC system, as signal loss or interruption can result in loss of control and potential crashes. The 2S LiPo chemistry provides excellent energy density, allowing Spektrum engineers to pack 2000mAh of capacity into a package weighing just 108 grams, making it ideal for weight-conscious applications where every gram matters. The battery's 14.8Wh total energy capacity ensures that even during extended RC flying sessions or marathon driving events, your receiver will maintain full operational capability. The 7.4V nominal voltage aligns perfectly with standard Spektrum receiver specifications, ensuring optimal performance across the entire voltage range during discharge. The 15C maximum continuous discharge rate provides substantial current delivery capability, ensuring the battery can supply whatever current your receiver and its connected servos demand without voltage sag or performance reduction. The inclusion of a JST-XH balance lead demonstrates Spektrum's commitment to battery longevity — balanced charging maintains cell voltage equilibrium, preventing cell imbalance that degrades battery performance over time. The EC3 connector, paired with 16 AWG power leads, ensures efficient power delivery with minimal resistance and voltage drop. Whether you're powering receivers in 1/10 scale RC cars across UK tracks, flying RC aircraft, or running RC helicopters, this battery's specifications have been carefully optimised to deliver reliable, consistent power in real-world operating conditions.

Frequently Asked Questions
- Is this battery suitable for use with my Spektrum receiver? — Yes, the SPM 2000mAh 2S 7.4V LiPo Receiver Battery is specifically designed for use with Spektrum receivers featuring EC3 connectors. The 7.4V nominal voltage and 2000mAh capacity make it compatible with virtually all modern Spektrum receiver systems. If your receiver uses EC3 connectors, this battery will be a direct fit.
- What charger should I use to charge this receiver battery? — You'll need a LiPo-compatible charger that supports 2S LiPo charging and features a JST-XH balance lead connector. Many modern RC chargers offer this capability. Charging at the standard 1C rate (2A) is recommended for maximum battery longevity, though the battery supports charging up to 6A (3C) for faster turnaround between sessions. Always use a charger with an integrated balancing function to maintain cell health.
- How long will this battery last per charge during typical RC flying or driving? — Runtime depends on your receiver and servo current draw, which varies by application. For typical receiver current draws of 200-400mA, you can expect 5-10 hours of continuous operation from the 2000mAh capacity. In practical RC usage, where sessions are typically 20-40 minutes, a single charge will power multiple driving or flying sessions before recharging becomes necessary.
- Can I use this battery in my RC car, aircraft, and helicopter? — This is a universal receiver battery designed specifically for powering receivers in any RC application — RC cars, buggies, trucks, helicopters, fixed-wing aircraft, or drones. As long as your receiver features an EC3 connector and operates at 7.4V nominal voltage, this battery will work perfectly. It's an excellent choice for RC hobbyists running multiple platforms using compatible receiver systems.
- What's the difference between the 2000mAh and smaller capacity receiver batteries? — The 2000mAh capacity provides significantly longer runtime compared to smaller 1000-1500mAh receiver batteries. If you frequently run extended sessions without access to charging, or if you're powering multiple servos from a single receiver, the larger 2000mAh capacity provides important runtime advantages. The trade-off is slightly increased weight and physical size, though at just 108 grams, this remains very lightweight for a receiver battery.
- How many charge cycles will this battery provide before degradation? — LiPo batteries typically provide 300-500 complete charge cycles when properly cared for. Consistent balanced charging, avoiding complete discharge, and storing the battery at approximately 50% charge between sessions will maximise lifespan. The JST-XH balance lead included with this battery is specifically designed to maintain cell balance, which directly contributes to extended battery life.
- Is this battery safe for indoor use in RC helicopters or aircraft? — Yes, LiPo batteries are standard in RC aviation. However, always follow your charger's safety instructions, use a LiPo charging bag as a safety precaution, and never leave the battery unattended during charging. The 2000mAh capacity and 14.8Wh energy rating are well within safe operating parameters for indoor RC flying.
