- Universal Compatibility — Whilst this specific model bridges IC2 devices with IC3 batteries, Spektrum's complete adapter range supports EC2, IC2, EC3, IC3, EC5 and IC5 plug types, giving you flexibility to build a complete connector ecosystem for your entire RC fleet.
- Compact and Lightweight — The adapter adds virtually no weight or bulk to your RC setup, making it ideal for weight-sensitive applications like RC drones, lightweight RC cars, and racing builds where every gram matters for performance.
Technical Performance
The Spektrum One-Piece Battery Adapter represents professional-grade connector engineering designed specifically for the demands of RC enthusiasts. The single-piece, gold-plated construction delivers exceptional reliability that standard plastic-bodied adapters simply cannot match, particularly important when you're connecting expensive LiPo batteries to valuable RC equipment. The internal Smart connection wire ensures full compatibility with Spektrum's intelligent battery ecosystem, allowing your RC batteries to report critical performance metrics to compatible charging systems, which helps prevent over-charging, over-discharging, and thermal damage that can reduce battery lifespan. The low-resistance design means minimal voltage drop during operation, preserving the full performance potential of your battery whether you're running a brushless RC motor at full throttle or carefully managing power in a precision RC crawling scenario. This adapter bridges the IC2 device connector (commonly found on receivers, ESCs and charging ports) with the IC3 battery connector (found on many Spektrum Smart batteries and other quality RC power sources), expanding your options for mixing and matching components across your RC collection. Whether you operate a single RC car, maintain a fleet of ready-to-run RC models, or build custom RC vehicles from kits, having quality adapters ensures you can focus on enjoying your hobby rather than wrestling with incompatible connectors. The gold plating particularly shines in humid UK conditions, resisting the corrosion that can plague standard brass connectors over time.

Frequently Asked Questions
- What exactly does the IC2 Device / IC3 Battery adapter do? — This adapter allows you to connect a battery featuring an IC3 connector (typically found on Spektrum Smart batteries) to a device with an IC2 connector port, such as a charger, ESC, or receiver. This is essential when you have newer equipment with one connector type but your battery uses a different connector standard, which is common when mixing RC equipment from different manufacturers or purchase dates.
- Why would I need this adapter for my RC car or RC truck? — Many RC enthusiasts gradually build their fleet over time, acquiring batteries and equipment with different connector types. Rather than purchasing entirely new batteries to match your device connectors, this affordable adapter lets you use your existing battery collection with all your RC vehicles, chargers, and accessories, saving substantial money whilst maintaining flexibility.
- Is this suitable for beginners? — Absolutely. The Spektrum adapter is one of the simplest RC accessories you can use—there are no settings to configure, no wiring to understand, and no installation required. Simply plug the battery connector into one end and the device connector into the other. Even complete beginners to RC hobbies will have no difficulty using this adapter safely and effectively.
- Will this adapter work with my RC drone, boat, or aeroplane? — Yes. Because the adapter simply bridges two connector types without any active components or limitations, it works with any RC application that uses IC2 and IC3 connectors—cars, trucks, drones, aeroplanes, boats, and any other RC device. The connector type matters far more than the specific application.
- What makes this Spektrum adapter better than cheaper alternatives? — The key differences are the one-piece solid construction (versus multi-part designs that can loosen), gold-plated contacts (versus bare brass that corrodes), and the internal Smart connection wire that maintains full compatibility with Spektrum's intelligent battery technology. Cheaper adapters often use flimsy plastic bodies and standard brass contacts that degrade quickly, particularly in the damp UK climate, whereas this Spektrum adapter is engineered for years of reliable use.
- Can I use this adapter to charge my battery? — Yes, you can use this adapter with compatible chargers. If your charger has an IC2 port and your battery has an IC3 connector, this adapter allows you to establish that connection for charging. The low-resistance design ensures efficient power transfer during charging without heat buildup.
- Why do I get two adapters instead of just one? — Spektrum includes two adapters per package for convenience and redundancy. You can set up multiple simultaneous connections for parallel charging or dual-device setups, or simply keep a backup adapter in your RC toolkit in case one needs cleaning or maintenance. Having spares means you're never interrupted during an RC bashing session.
- Is this adapter compatible with EC2 or EC3 connectors? — No. This specific adapter connects IC2 devices with IC3 batteries. Spektrum makes separate adapters for EC2, EC3, EC5, and IC5 connectors. An important note: IC2 batteries are not compatible with EC2 devices, so ensure you're matching the correct connector standards for your specific equipment.
