Etronix Male Deans To Two 4.0mm Male Connector Adapter ET0836

Overview

The Etronix Male Deans To Two 4.0mm Male Connector Adapter ET0836 is an essential adapter for RC enthusiasts in the UK who need to bridge between two of the most popular power connector standards used in modern RC cars, trucks, buggies and crawlers. Whether you're running a brushless RC buggy, an electric RC monster truck, or any other high-performance RC vehicle, you'll often find yourself working with mixed connector types across your fleet of batteries, ESCs and chargers. This adapter provides a straightforward, tidy solution that eliminates the need for custom wiring or soldering, saving you time and ensuring safe, reliable connections every single time.

The Deans connector, also known as the T-Plug, has become the industry standard for serious RC hobbyists across the UK and worldwide, offering excellent current handling and a secure connection. The 4.0mm bullet connectors are equally popular, particularly in systems designed for slightly lower current applications or where space is at a premium. By combining one male Deans connector with two male 4.0mm connectors, the ET0836 adapter allows you to interface systems that would otherwise require separate cables or adapters, making it invaluable for anyone running multiple RC vehicles or battery systems.

This adapter is manufactured by Etronix, a trusted brand recognised throughout the RC hobby community for producing high-quality, reliable connector solutions. Whether you're a seasoned competitor preparing your race vehicle, a weekend basher maintaining multiple vehicles, or someone new to RC who's building their first setup, this adapter will prove to be a genuinely useful addition to your RC workshop. Available now from RC Model Shop, a leading UK RC retailer with expert knowledge and a physical store in Walsall, this adapter represents excellent value and reliable engineering.

Key Features

• Male Deans to Dual 4.0mm Male Configuration — This adapter provides one male Deans T-Plug connector on one end and two male 4.0mm bullet connectors on the other end, allowing you to split a single Deans connection into two 4.0mm connections, or vice versa, which is incredibly useful when integrating different battery systems, chargers or ESCs in your RC setup.
• Straightforward Interface Between Popular RC Standards — The Deans connector and 4.0mm bullet connectors represent two of the most widely used power connector types in the RC hobby, so this adapter ensures broad compatibility across a huge range of RC vehicles and equipment without requiring custom wiring or professional soldering.
• Quality Etronix Manufacturing — Built to the high standards you expect from Etronix, this adapter ensures reliable electrical contact and secure mechanical connection, which is absolutely critical when dealing with the power demands of modern brushless RC systems.
• Compact and Tidy Design — The adapter provides a clean, organised way to connect incompatible connector types without the clutter of multiple cables or the safety risks of makeshift solutions, helping you maintain a professional-looking RC setup.
• Essential Workshop Tool — For anyone running more than one RC vehicle or battery system, this adapter is an essential piece of workshop equipment that will pay for itself many times over in convenience and safety, allowing you to use the same battery or charger with vehicles equipped with different connector types.

Technical Performance

The Etronix ET0836 adapter is engineered with solid electrical and mechanical design suitable for the demands of modern brushless RC cars and trucks. The Deans connector side features the characteristic low-resistance, high-current-capacity design that has made Deans connectors the choice of serious RC racers and bashers throughout the UK and internationally. The dual 4.0mm male connectors on the opposite end are precision-formed to ensure tight, secure engagement with corresponding female 4.0mm sockets, eliminating the loose connections that can lead to voltage drop and poor performance. The adapter itself requires no power source—it is purely a passive connector interface—making it suitable for use with any battery chemistry (LiPo, NiMH, LiFe) and any voltage combination (2S, 3S, 4S, 6S and beyond). Whether you're charging your batteries, running them through an ESC to a brushless motor, or testing electrical connections, this adapter will handle the task reliably. The construction quality ensures that repeated connections and disconnections won't wear out the connector contacts, meaning you'll get years of reliable service from this simple but essential accessory.

Frequently Asked Questions

• What is a Deans connector and why is it used in RC cars? — The Deans connector, officially known as the Deans T-Plug, is a two-pin power connector that has become the industry standard for modern RC vehicles because it offers excellent current-carrying capacity (up to 60 amps continuous in many applications), a secure mechanical connection that resists accidental disconnection, and low electrical resistance which minimises voltage drop. Almost every brushless RC car sold in the UK today uses either Deans connectors or equivalent high-current connectors.
• What are 4.0mm bullet connectors used for in RC? — The 4.0mm bullet connector (also called 4mm bullet connector) is a versatile power connector consisting of two cylindrical pins that are widely used in RC applications where moderate current is required, such as charger connections, ESC signal lines, or smaller battery packs. They're popular because they're simple, affordable, and widely available across the RC hobby.
• Why would I need an adapter that converts Deans to 4.0mm connectors? — You might need this adapter if you own multiple RC vehicles with different connector types—for example, an older RC buggy with 4.0mm connectors and a newer brushless RC monster truck with Deans connectors. Instead of buying separate batteries for each vehicle, this adapter lets you use the same battery pack across both vehicles, or allows you to use a single Deans-equipped charger with older 4.0mm battery packs.
• Can I use this adapter with LiPo batteries? — Yes, absolutely. This adapter is completely chemistry-neutral—it will work safely with LiPo batteries, NiMH batteries, LiFe batteries, or any other battery chemistry. The adapter itself handles no power conversion, so the voltage and chemistry of your battery makes no difference to its operation. However, always follow safe LiPo charging practices and never leave LiPo batteries unattended while charging.
• Is this adapter suitable for high-current brushless RC applications? — The Deans side of this adapter is rated for high-current applications typical of brushless RC vehicles. The 4.0mm side may be more limiting depending on the specific gauge of wire used, but for most standard RC applications combining moderate-draw 4.0mm systems with Deans-equipped vehicles, this adapter will perform reliably. For maximum safety and performance, verify that the wire gauge of the 4.0mm connectors is appropriate for your ESC's current rating.
• What is the difference between this adapter and the Etronix Male Deans To 4.0mm Connector with Housing Adapter? — The key difference is that the ET0836 adapter you're looking at provides TWO 4.0mm male connectors (allowing you to split one Deans connection into two 4.0mm connections), whilst the alternative model provides a single 4.0mm connection but includes protective housing around the connector. Choose the ET0836 if you need to connect two separate 4.0mm devices to a single Deans source, or choose the housing version if you need a single connection with extra protection against dust and accidental contact.
• Can I use this adapter in reverse—connecting two Deans-equipped devices to a single 4.0mm source? — Technically yes, the adapter works bidirectionally, but in practice this is not recommended because you'd be trying to draw current from a single 4.0mm connector to power two Deans-equipped devices, and 4.0mm connectors typically have lower current ratings than Deans connectors. Stick to using the adapter as designed: one Deans source, two 4.0mm destinations, or one 4.0mm source and one Deans destination.
• Is this adapter a permanent solution or a temporary workaround? — Whilst this adapter will work indefinitely and can last for many years with proper care, it's best viewed as a bridging solution. If you find yourself using an adapter regularly between two vehicles, you might eventually consider re-connectorising one of them to match the other, which will give you a cleaner, more integrated solution. For occasional use or temporary testing, this adapter is perfect.
