Key Features
- 10500mAh High Capacity — The 10,500 milliamp-hour capacity delivers extended operating time compared to standard transmitter batteries, allowing you to complete entire RC racing heats, flying sessions, or practice runs without needing to recharge mid-session, which is particularly valuable during competitive events or when you have multiple vehicles to operate.
- 3.7V Lithium-Ion Chemistry — Lithium-ion technology provides superior energy density and consistent voltage output throughout the discharge cycle, meaning your transmitter maintains steady performance from full charge down to low battery warning, unlike older NiMH batteries that experience gradual voltage sag affecting control precision and range.
- Official Spektrum Replacement — This is the genuine factory replacement battery engineered specifically for Spektrum iX14, iX14+ and similar series transmitters, guaranteeing full compatibility, optimal charging characteristics, and integration with your radio's battery management system without compatibility concerns or risk of damage.
- Included Protective Battery Case — The battery arrives with a protective carrying case specifically designed for this battery format, which safeguards the cells during transport to RC tracks or flying fields, protects against physical damage, and helps maintain proper storage conditions, extending overall battery lifespan and maintaining safety.
- 1S Single-Cell Configuration — The single-cell design delivers 3.7V nominal voltage, which is the standard operating voltage for Spektrum iX14 and iX14+ transmitters, ensuring perfect compatibility with your radio's charging system, power management electronics, and performance characteristics without requiring any adapters or modifications.
Technical Performance
The SPM 3.7V 1S 10500mAh LiIon Transmitter Battery represents modern lithium-ion battery engineering specifically adapted for RC transmitter applications. At 3.7V nominal voltage across a single cell (1S configuration), this battery delivers the precise power characteristics required by Spektrum's iX14 and iX14+ radio control transmitters. The 10,500mAh capacity represents a substantial increase in available energy compared to standard OEM transmitter batteries, directly translating to significantly longer operational sessions—essential when competing at UK RC car racing events, drone flying competitions, or engaging in extended practice sessions with multiple vehicles. Lithium-ion chemistry provides superior performance characteristics compared to older nickel-metal hydride (NiMH) batteries, including more consistent voltage delivery throughout the discharge cycle, reduced self-discharge when sitting idle, and greater energy density allowing this higher capacity to fit within the same physical footprint as lower-capacity older technologies. The included protective case demonstrates attention to proper lithium-ion battery care—a critical consideration since these cells require careful handling and appropriate storage conditions to maintain safety and performance longevity. Build quality reflects Spektrum's reputation as a leading RC electronics manufacturer, with proper cell selection and internal protection circuitry to guard against over-discharge, over-current conditions, and thermal issues that could compromise safety or lifespan.

Frequently Asked Questions
- Is the SPM 3.7V 10500mAh battery compatible with my Spektrum iX14 transmitter? — Yes, this battery is the official replacement for Spektrum iX14 and iX14+ transmitters, providing guaranteed compatibility with all electrical systems, charging circuits, and voltage requirements of these radio models. It will function as a direct drop-in replacement for the original battery that shipped with your transmitter.
- How much longer will I be able to operate my transmitter on this battery compared to the standard battery? — The 10,500mAh capacity represents a substantial increase in available energy, directly extending operating time proportionally. Your actual runtime depends on transmitter usage patterns, radio features being employed, and environmental conditions, but the significantly higher capacity means considerably longer sessions between necessary recharges.
- What is the difference between this 1S lithium-ion battery and older NiMH transmitter batteries? — Lithium-ion technology offers several advantages: superior energy density (more power in the same size), more consistent voltage throughout discharge (meaning better performance from full charge to low battery), lower self-discharge rates during storage, and reduced memory effect issues. NiMH batteries gradually lose voltage as they discharge, potentially affecting transmitter range and responsiveness as the battery depletes, whereas lithium-ion maintains steadier output.
- Can I use this battery with other Spektrum transmitter models? — This battery is specifically engineered for iX14 and iX14+ transmitters. Whilst other Spektrum radios may accept 3.7V lithium-ion batteries, you should verify specific compatibility with your particular model before use, as connector types and charging systems can vary across different transmitter generations.
- How do I properly care for my lithium-ion transmitter battery? — Store the battery in the included protective case when not in use. Avoid leaving it fully charged for extended periods or fully discharged for extended storage. Charge using only the charging system designed for your Spektrum transmitter. Never expose lithium-ion batteries to extreme temperatures, moisture, or physical damage. Proper care maximises lifespan and maintains safety.
- Is this battery suitable for beginners in RC hobbies? — Absolutely. This official Spektrum replacement battery is designed for all skill levels, from those just discovering RC hobbies in the UK to experienced competitors. The included protective case and straightforward charging method make it user-friendly, whilst the generous 10,500mAh capacity makes it practical even for beginners who value extended session times without constant recharging interruptions.
