Mastering RC Power Connections with HobbyKing

Introduction: The Core of Every RC System – Power Connectors

In the world of RC enthusiasts and professionals, the right power connector can make or break your performance. Whether you're flying high-speed FPV drones, piloting aerobatic planes, or racing electric RC cars, ensuring a secure and efficient connection between your battery and ESC is non-negotiable.

As a global leader in RC components, HobbyKing offers a wide range of high-quality connectors, balance boards, and accessories tailored to every RC application. In this guide, we’ll explore four essential components — the EC5 connector, XT60 plug, JST-XH balance board, and Deans T plug — so you can make informed, performance-oriented decisions.

Part 1: What is the EC5 Connector and Why Is It Built for Power?

The EC5 connector is a high-current 5mm bullet-style plug designed for demanding RC applications. Its name stands for "Electric Connector 5mm," and it's commonly used with large-capacity LiPo batteries (6S to 8S) in high-powered drones, boats, and RC aircraft.

✅ Key Benefits of EC5 Connectors:

• Handles up to 120A continuous current, ideal for power-hungry systems
• Features tight-fitting housings to prevent disconnections during high vibration
• Copper plating and heavy-duty design reduce resistance and heat build-up

Why HobbyKing Recommends It:

HobbyKing’s high-performance battery lines, like the Turnigy Heavy Duty Series, are often compatible with EC5 connectors due to their reliability in extreme applications. EC5 connectors are especially favored in aerobatics and FPV long-range drones where power stability is critical.

Part 2: XT60 Plug – The Golden Standard for RC Enthusiasts

The XT60 plug is arguably the most widely used connector in RC hobbies today. It strikes the perfect balance between performance, size, and usability, making it ideal for 3S to 6S LiPo batteries used in drones, RC planes, and vehicles.

✅ Advantages of XT60 Plugs:

• Supports up to 60A continuous current
• Made from heat-resistant nylon with gold-plated connectors
• Easy to solder, plug, and unplug with tight, reliable connections
• Pre-installed on many HobbyKing battery models

HobbyKing Integration:

From the ZIPPY Compact Series to Turnigy Graphene LiPos, XT60 is a default connector type offered by HobbyKing. It’s compatible with most modern chargers, ESCs, and battery trays, making it a go-to solution for everyday RC setups.

Part 3: JST-XH Balance Board – The Unsung Hero of Battery Health

While main connectors handle raw power, JST-XH balance boards are crucial for battery health and charging safety. These boards allow balance chargers to individually monitor and charge each cell in a LiPo battery, ensuring optimal performance and lifespan.

✅ Features of JST-XH Balance Boards:

• Compatible with 2S to 8S LiPo batteries
• Standardized design ensures cross-brand compatibility
• Prevents cell overcharge or undervoltage damage
• Affordable and easy to integrate into any setup

�� Why Choose HobbyKing:

HobbyKing provides various balance boards and extensions for JST-XH systems, ideal for use with chargers like the IMAX B6, ISDT, or SkyRC models. JST-XH is the most common balance connector across LiPo batteries on the market, and HobbyKing’s offerings ensure 100% compatibility.

Part 4: Deans T Plug – The Old-School Favorite Still Going Strong

The Deans T plug, or T-style connector, has been a staple in the RC world for decades. Though newer designs like XT60 have become more popular, many RC veterans still prefer Deans connectors for their compact size and proven reliability.

✅ Benefits of Deans T Plugs:

• Supports around 60A continuous current
• Compact design, perfect for tight installations
• Simple shape ensures solid polarity and tight fit
• Widely available and budget-friendly

⚠️ Considerations:

While efficient, the Deans plug can be harder to solder than XT60s due to its smaller surface area. Nonetheless, for custom builds and hobbyists familiar with its format, the Deans T plug remains a solid, dependable option — and it’s available across many HobbyKing products and accessories.

Connector Comparison: Choosing the Right Option for Your RC Build

HobbyKing Recommendation:
Choose the EC5 connector for extreme performance builds, XT60 plugs for everyday use, Deans T plugs for compact DIY projects, and always pair with a reliable JST-XH balance board for battery longevity and safety.
