Key Features
- Smart Battery Technology — The integrated Smart circuitry monitors cell voltage, temperature and battery health continuously, providing vital information that helps prevent over-discharging and damage whilst extending the overall lifespan of your battery investment.
- 4S Configuration (14.8V nominal) — Four cells in series deliver 14.8 volts, which is the standard voltage for many mid-sized electric RC models, ensuring excellent compatibility with brushless RC setups across cars, trucks and aircraft.
- 2700mAh Capacity — This capacity represents a sweet spot for balance between runtime and weight, giving you substantial flight or run times without excessive bulk or unresponsive handling characteristics.
- 30C Continuous Discharge Rate — The battery can deliver up to 81 amps of continuous discharge current, which means it has the power reserves for aggressive flying, high-speed runs and demanding acceleration without voltage sag that would compromise performance.
- IC3 Connector — The IC3 connector is a widely-recognised standard in the RC hobby community, ensuring compatibility with numerous Spektrum products and chargers, making this battery a versatile addition to your RC battery collection.
- JST-XH Balance Connector — The balance connector allows your charger to monitor and balance each individual cell during charging, ensuring all four cells remain at equal voltage for optimal battery health and safety.
- 1C Standard Charge Rate — Charging at 1C (2.7 amps) gives you a measured, safe charging profile that minimises stress on battery cells and promotes longevity, with a typical full charge taking approximately one hour.
- Compact Dimensions — Measuring 5.43 inches long, 1.69 inches wide and 0.83 inches tall, this battery's modest footprint makes it ideal for fitting into tight battery compartments in modern RC airframes and car chassis designs.
Technical Performance
The Spektrum SPM 2700mAh 4S Smart LiPo represents contemporary battery engineering tailored for serious RC pilots and drivers. With a nominal voltage of 14.8V across four cells (3.7V per cell), this LiPo battery operates in the voltage sweet spot that modern brushless motor systems expect, delivering responsive throttle response and consistent power delivery throughout the discharge cycle. The engineering achieves a remarkable power-to-weight ratio, with the battery weighing just 271 grams (9.56 ounces), ensuring it won't create unwanted tail-heavy or nose-heavy characteristics in your RC model. The 30C continuous discharge rating of 81 amps means the battery supplies abundant power for sustained high-throttle manoeuvres, whether you're executing inverted aerobatic loops in an electric RC aeroplane or launching your brushless RC car across jumps at full acceleration. The Smart technology continuously monitors internal cell voltage and battery temperature, automatically cutting power if dangerous conditions are detected, which represents a significant safety advantage over passive batteries. Build quality reflects Spektrum's industry reputation, with robust connector interfaces, reliable cell balancing through the JST-XH connector, and construction standards that meet recognised safety requirements. The 1C charge rate of 2.7 amps, whilst conservative, ensures maximum cell longevity and minimises heat generation during the charging process, meaning your battery will maintain peak performance through hundreds of charge cycles.

Frequently Asked Questions
- What is a 4S LiPo battery and why does voltage matter for my RC equipment? — A 4S LiPo battery contains four lithium polymer cells connected in series, providing 14.8 volts nominal output (and up to 16.8 volts when fully charged). Voltage is critical because RC motors, ESCs and servos are rated for specific voltage ranges. This 4S battery is the standard power source for mid-sized electric RC cars, trucks and aeroplanes, and matching the correct voltage to your equipment prevents damage and ensures proper performance.
- What does the 30C discharge rating mean, and do I need a high C-rating? — The 30C rating indicates the battery can safely discharge at 30 times its capacity continuously, equalling 81 amps in this case. A higher C-rating means the battery can provide more current without voltage sag, which is important for high-performance applications. If you're flying aggressive aerobatics or running competitive racing setups, a 30C battery ensures the power delivery remains snappy and responsive.
- How long will this battery last on a single charge? — Runtime depends entirely on your specific RC model, its motor's current draw, and flying or driving style. Generally, a 2700mAh battery in a mid-sized electric RC aeroplane will provide 8-15 minutes of flight time, whilst in an electric RC car the runtime might extend to 20-30 minutes depending on throttle usage and terrain. Aggressive driving or flying consumes more capacity, reducing runtime accordingly.
- What does Smart battery technology do, and is it worth the premium? — Spektrum Smart batteries integrate electronic circuitry that monitors voltage, temperature and battery health. This technology prevents dangerous over-discharge conditions, optimises charging cycles, and provides data to compatible chargers that can alert you to issues before battery damage occurs. For anyone serious about preserving their battery investment and ensuring safe operation, the Smart features justify the cost.
- Can I use this battery with non-Spektrum RC equipment? — The IC3 connector is an industry-standard connector used by many RC manufacturers beyond Spektrum, so you can use this battery with any equipment featuring an IC3 socket. However, the Smart battery features only work fully with Spektrum-compatible chargers and receivers. Even without Smart features activated, the battery functions as a standard 4S LiPo in any IC3-equipped RC model.
- How should I store this battery when not in use? — Whilst specific storage instructions are not detailed in the manufacturer specifications, best practice for any LiPo battery is to store it in a cool, dry location at partial charge (around 3.85V per cell) rather than fully charged or completely depleted. This maximises long-term lifespan and maintains battery health between uses.
- Is this battery suitable for beginners? — If you're new to the RC hobby and just purchased your first ready-to-run RC model, check whether it accepts a 4S battery before purchasing. For experienced RC pilots and drivers, this battery is straightforward and reliable. However, LiPo batteries require respect regarding charging safety and storage precautions, so you should familiarise yourself with LiPo battery safety practices before use.
