Key Features
- 7.4V Nominal Voltage — This two-cell lithium-ion configuration delivers 7.4 volts, providing the exact voltage specification required by Spektrum DX9, DX7S, and DX8 transmitters for optimal performance and reliable operation throughout your flying or driving sessions.
- 2000 mAh Capacity — The substantial 2000 milliamp-hour capacity ensures extended transmitter runtime, allowing you to conduct multiple flights, races, or driving sessions on a single charge without needing frequent battery changes during your RC activities.
- 2S1P Cell Configuration — This two-cell series, single-parallel arrangement delivers balanced voltage and current characteristics, optimising both power delivery and battery longevity for your Spektrum transmitter systems.
- Lithium-Ion Technology — Modern LiIon chemistry provides superior energy density compared to older NiMH batteries, meaning you get more runtime and consistent voltage delivery throughout the discharge cycle, with less memory effect and superior reliability.
- White 2-Pin Connector — The standardised Spektrum white 2-pin connector ensures perfect compatibility and safe, foolproof connection to your DX9, DX7S, or DX8 transmitter without risk of reverse polarity or incompatible connector damage.
- Compact Dimensions — Measuring just 70 mm in length, 36 mm in width, and 19 mm in height, this battery pack is specifically designed to fit seamlessly into your transmitter without adding bulk or affecting ergonomics during operation.
- Lightweight Construction — At only 95 grams (3.35 oz), this battery adds minimal weight to your transmitter, preserving the balance and comfortable handling characteristics of your Spektrum DX-series radio system.
- 3.3V Per Cell Rating — Each cell delivers 3.3 volts of nominal voltage, which when paired in series creates the precise 7.4V output your DX9, DX7S, or DX8 requires for peak transmitter performance and receiver signal strength.
Technical Performance
The SPM 2000 mAh TX Battery represents the pinnacle of transmitter power technology, engineered with Spektrum's meticulous attention to quality and performance standards. The lithium-ion chemistry delivers superior consistency compared to older nickel-metal hydride (NiMH) alternatives that were common in older RC transmitters. With a total energy capacity of 14.8 Watt-hours, this battery provides reliable, sustained power delivery across the entire discharge cycle, meaning your transmitter maintains consistent signal strength and response throughout extended RC sessions. The precise 7.4V specification is critical for Spektrum DX9, DX7S, and DX8 transmitters—these sophisticated radio systems require exact voltage parameters to deliver the 2.4 GHz signal quality and receiver bind security that separates professional-grade RC systems from basic alternatives. UK RC enthusiasts choosing Spektrum transmitters—whether for competitive drone racing, FPV flight, or serious RC car and truck racing—appreciate the engineering that goes into every battery. The LiIon technology eliminates the memory effect problems that plagued older NiMH batteries, meaning you can charge this battery at any state of discharge without degrading its capacity. The white 2-pin connector is specifically engineered to the Spektrum standard, ensuring perfect contact pressure and safe, secure connections that prevent the intermittent signal losses that can ruin a race or crash an expensive aircraft.

Frequently Asked Questions
- Is this battery compatible with my Spektrum transmitter? — Yes, the SPM 2000 mAh TX Battery is specifically designed for Spektrum DX9, DX7S, and DX8 transmitters. It features the white 2-pin connector that these radio systems use, and the 7.4V output matches the exact voltage specification these transmitters require. Always verify your transmitter model before purchasing to ensure compatibility.
- How long does this battery last on a single charge? — The 2000 mAh capacity provides excellent runtime for extended RC sessions. Actual flight or driving time depends on your transmitter usage patterns—continuous stick input and light brightness draw more power than idle monitoring. Most users find this capacity sufficient for multiple flights or racing runs before needing a recharge.
- What makes lithium-ion better than the older NiMH batteries? — Lithium-ion technology delivers higher energy density, meaning more power in a smaller, lighter package. LiIon batteries have virtually no memory effect, so you can recharge at any state of discharge without degrading capacity. They also maintain more consistent voltage throughout the discharge cycle, ensuring your transmitter performs reliably until the battery is nearly depleted.
- Can I use this battery in other Spektrum transmitters? — This battery is specifically designed for DX9, DX7S, and DX8 models. Other Spektrum transmitters may use different voltage requirements or connector types. Always consult your transmitter manual or contact the manufacturer to confirm compatibility before attempting to use this battery in any other radio system.
- How should I store and maintain this battery? — Store the battery in a cool, dry place away from extreme heat or moisture. If storing for extended periods, maintain a partial charge (around 50%) rather than leaving the battery fully charged or completely depleted. This practice maximises the long-term lifespan of lithium-ion cells.
- Is this a genuine Spektrum product? — Yes, the SPM 2000 mAh TX Battery is manufactured by Spektrum, the RC division of Horizon Hobby, and carries the genuine Spektrum quality standards and warranty support that serious RC enthusiasts depend upon.
