Frequently Asked Questions

• What connectors does the Etronix ET0280 support? — The Etronix ET0280 provides terminations for six popular connector types: Deans, Futaba, JST, Tamiya, EC3, and TRX styles. It also includes a DIY extra wire for custom applications. This comprehensive range covers the vast majority of RC equipment available, from entry-level starter sets to high-end competitive RC cars and trucks.
• Is this adapter suitable for beginners? — Yes, absolutely. The ET0280 is ideal for beginners because it eliminates one of the most common frustrations newcomers face: incompatible connectors between batteries and chargers. If you're just getting into RC and have equipment from different manufacturers, this single lead provides a simple solution without requiring soldering skills or advanced knowledge.
• What is the 4.0mm connection? — The 4.0mm connector is the primary input point on this adapter lead. It's a widely-used standard in RC applications, commonly found on quality RC batteries, chargers, and power distribution systems. The 4.0mm specification refers to the diameter of the connector pins, providing reliable electrical contact for power transfer.
• Can I use this with any RC vehicle? — The Etronix ET0280 is compatible with any RC application that uses one of its supported connector types: Deans, Futaba, JST, Tamiya, EC3, or TRX. This covers RC cars, RC trucks, RC buggies, RC crawlers, and virtually any other RC vehicle type. Compatibility depends on what connectors your specific battery, charger, and RC electronics use rather than the vehicle type itself.
• What batteries can I use this adapter with? — The ET0280 is a passive adapter lead that works with any battery type that has one of its supported connector types (Deans, Futaba, JST, Tamiya, EC3, or TRX). This includes LiPo batteries (from 2S to 6S and beyond), NiMH batteries, and other RC power systems. Simply match the connector on your battery to one of the available terminations on this lead.
• Is the DIY extra wire meant for soldering? — The DIY extra wire component provides flexibility for custom applications. Experienced RC builders and technicians can use this wire to create bespoke connections or extend the functionality of the lead for specialised RC setups. If you're not experienced with electrical connections, we recommend consulting with experienced RC enthusiasts at RC clubs or forums before attempting custom modifications.
• How does this compare to having multiple separate adapters? — Rather than purchasing individual adapters for each connector type (Deans-to-Futaba, Tamiya-to-JST, etc.), the ET0280 consolidates all these options into one handy lead. This saves money, reduces clutter in your RC workshop, and ensures you always have the right adapter on hand without having to hunt through a pile of connectors.
• Will this work with my Traxxas RC vehicle? — Yes, if your Traxxas vehicle uses TRX-style connectors (which many Traxxas models do), the ET0280 includes TRX termination for full compatibility. This makes it particularly useful for UK RC enthusiasts who run Traxxas equipment alongside vehicles from other manufacturers.
