EC5 Device & Battery Connector

The EC5 connector that keeps your equipment always online

The EC5 Device & Battery Connector (ref. DYNC0023) is a high-current EC5-type connector designed to securely and stably connect devices and batteries with minimal energy loss. Its EC5 format — with a 5 mm diameter pin — is one of the most widely used standards in the world of radio control and model electronics, and for good reasons: it offers a large contact surface, easy insertion and extraction, and mechanical retention that prevents accidental disconnections.

Main features

• EC5-type connector, 5 mm diameter pin.
• Includes device connector and battery connector to form the complete pair.
• Designed to withstand high currents of direct current.
• Heat-resistant plastic body with high conductivity metal contacts.
• Positive insertion system that ensures a firm and vibration-free connection.
• Reference: DYNC0023.

Recommended applications

This connector is designed for installations where electrical reliability is non-negotiable: high-capacity LiPo batteries, speed controllers, power systems for competition RC equipment, and any circuit that demands high current flow. If you are assembling or refurbishing a battery pack, or need to change the connector on your speed controller or charger, the EC5 is a mature and proven choice.

Assembly and preparation

The soldering process is straightforward if good practices are followed: heat the connector well before applying solder (EC5 connectors act as heat sinks and require a sufficiently powerful soldering iron), apply flux for a clean joint, and allow to cool before inserting. Protect the wires with heat shrink once soldering is complete to avoid accidental short circuits.

Frequently asked questions

What is the difference between the device connector and the battery connector in an EC5?

The device connector has male pins (plugs) and is typically installed on the speed controller or energy receiver equipment, while the battery connector has female sockets and is mounted on the cell pack. This mechanical polarization prevents connection reversals.

Is the EC5 compatible with the EC3 or EC2?

No, the pin sizes are different (5 mm in EC5 compared to 3.5 mm in EC3 and 2 mm in EC2), so they are not physically interchangeable. If you need to connect equipment with different standards, specific adapters are available.

What soldering iron power is recommended for the EC5?

Since the metal body of the connector dissipates heat quickly, a soldering iron of at least 60-80 W is recommended to achieve a clean joint without unnecessarily prolonging the application of heat on the plastic of the connector.

How many units does reference DYNC0023 include?

The available information indicates that it consists of one device connector and one battery connector (the complete functional pair). Confirm the exact units on the product sheet of the store.

Can the EC5 connector be reused after desoldering?

In principle, yes, as long as the contacts show no deformation or solder residue that reduces the passage section. Visually inspect the connector before reusing it and replace it if you detect signs of arcing or discoloration.

The EC5 Device & Battery Connector (DYNC0023) is a high-current EC5-type connector designed for reliable battery and device connections in RC cars, LiPo battery packs, and competition-grade electronics. With its 5 mm bullet contact, secure mechanical fit and low resistance, it is the go-to standard for hobbyists and RC racers who demand consistent power delivery.
