Key Features
- IC3 Charger Connection — The adapter features an IC3 plug on the charger side, which is the standard connector used by Spektrum chargers and battery management systems, allowing you to safely charge your batteries without the need for separate charging adaptations.
- 5mm Bullet Battery Connection — The opposite end terminates in dual 5mm bullet plugs that connect directly to your battery pack, providing robust mechanical contact and reliable electrical transfer during use and charging cycles.
- 2 Feet Wire Length — At 2 feet in length, the adapter provides enough cable to reach from your charger to your battery pack with practical routing flexibility, without excessive cable bulk that could create workspace clutter or handling difficulties.
- Wrapped Cable Construction — The wires are wrapped for added durability and protection, reducing the risk of abrasion damage from contact with sharp edges or repeated handling during typical RC operation and storage.
- Smart 2S Compatibility — Specifically designed for 2S LiPo battery packs, this adapter works seamlessly with Spektrum Smart battery technology, which provides enhanced safety features and cell monitoring capabilities.
- Professional Grade Reliability — Manufactured by Spektrum, a trusted name in RC electronics, this adapter meets the high standards expected by competitive racers, weekend bashers, and hobbyists alike across the UK RC community.
Technical Performance
The Spektrum IC3 Battery / 5mm Bullet Smart 2S Adapter represents precision engineering in connector design. The IC3 connector on the charger side is engineered to match Spektrum's charger specifications perfectly, ensuring proper polarity alignment and secure mechanical connection every time you plug in your battery for charging. The 5mm bullet connectors on the battery side are industry-standard components that provide excellent current carrying capacity whilst maintaining reliable contact through repeated connection cycles. The 2-foot length of the adapter cable strikes an optimal balance between practical reach and minimal cable mess—long enough to connect your charger to a battery pack positioned at a safe distance, yet short enough to keep your charging station organised and tidy. The wrapped construction of the cable provides mechanical protection against accidental abrasion, extending the service life of the adapter and protecting against shorts caused by damaged insulation. This adapter is specifically optimised for 2S LiPo battery packs running with Spektrum Smart battery technology, which monitors individual cell voltages and reports battery health data back through compatible Spektrum systems. The connector pairing ensures smooth integration into any Spektrum-based RC ecosystem, whether you're charging multiple batteries for a day at the track, managing a collection of ready to run RC models, or maintaining a fleet of brushless RC vehicles for competition use.

Frequently Asked Questions
- What is the IC3 connector and why does my Spektrum charger need this adapter? — The IC3 connector is Spektrum's proprietary charging connector standard used on their chargers and Smart battery management systems. If your charger features an IC3 output but your battery pack terminates in 5mm bullet connectors, this adapter creates a compatible bridge between them, allowing you to safely charge your batteries without soldering or permanent modifications.
- Is this adapter suitable for beginners in RC? — Yes, absolutely. This adapter is ideal for beginners who have purchased Spektrum chargers and Smart batteries but need a simple connection solution. It requires no technical knowledge to use—simply plug the IC3 end into your charger and the bullet ends into your battery, and you're ready to charge.
- Can I use this adapter with batteries other than 2S LiPo packs? — This adapter is specifically designed and tested for 2S LiPo battery packs with Smart battery technology. Using it with other battery types, configurations, or voltage ratings is not recommended and could compromise safety or charging performance.
- How long will this adapter last? — With proper care and storage, Spektrum connectors are renowned for their durability and longevity. The wrapped cable construction protects against wear and tear. Avoid exposing the adapter to extreme temperatures or moisture, and always handle the connectors gently when plugging and unplugging to maintain optimal contact quality over thousands of charge cycles.
- Do I need multiple adapters? — If you operate multiple batteries and want the convenience of leaving adapters connected to each battery pack rather than swapping a single adapter between packs, purchasing additional units allows faster battery rotation and more efficient charging station workflows.
- Is this the same adapter that comes with Spektrum Smart batteries? — Many Spektrum Smart battery packs do include adapters, but if you've lost yours, need a backup, or have purchased additional batteries that didn't include an adapter, the SPMXCA316 is the genuine Spektrum replacement part that guarantees compatibility.
