Introduction
If you're into RC planes, drones, cars, or boats, you know how important reliable power connections are. Choosing the right connector can make a big difference in performance and safety. In this post, we'll compare three popular connectors used in RC power systems: XT60, XT90, and bullet connectors. By the end, you'll have a clear idea of which one suits your project best.
What Are These Connectors?
XT60 and XT90 connectors are plastic housings with integrated metal contacts designed specifically for high-current battery connections. They are widely used in the RC community for their reliability and ease of use.
Bullet connectors are simple cylindrical metal connectors that plug directly into each other, often used with custom wiring setups. They come in various sizes and current ratings.
XT60 Connectors
XT60 connectors are rated for up to 60 amps of continuous current. They feature a secure, keyed design that prevents reverse polarity connections. The connectors are made from heat-resistant nylon and gold-plated connectors inside, ensuring a solid electrical connection.
They are common in smaller to medium-sized RC setups like 3S or 4S LiPo batteries powering drones, smaller planes, or cars.
XT90 Connectors
XT90 connectors are a beefier version, rated for up to 90 amps continuous current. They are physically larger than XT60s and offer a more robust connection for higher power setups.
Use XT90 connectors if you’re running bigger LiPo packs (like 6S or 8S batteries) or high-current ESCs and motors, such as those in large drones, trucks, or boats.
Bullet Connectors
Bullet connectors are cylindrical metal plugs, typically available in sizes ranging from 3.5mm to 6mm or more. They’re often used in custom wiring or when you want easy disconnection of components like motors or ESCs.
Bullet connectors can handle high currents, but their quality varies widely depending on materials and soldering. They don’t have keyed housings, so reversed connections are possible unless you take care.
Comparison Summary
- Current Rating: XT60 up to 60A, XT90 up to 90A, bullet connectors depend on size but can range from 30A to over 100A.
- Physical Size: XT60 is compact, XT90 is larger for higher current, bullet connectors vary.
- Polarity Protection: XT connectors are keyed to prevent wrong connections; bullet connectors are not.
- Ease of Use: XT connectors plug in easily and securely; bullet connectors require careful alignment.
- Durability: Both XT connectors offer good mechanical strength; bullet connectors can be less secure unless properly crimped or soldered.
Which Should You Choose?
For most hobby RC pilots and makers in the UK, XT60 connectors are a reliable choice for smaller to medium power systems. They're easy to find, affordable, and offer good performance.
If your project demands higher current, such as bigger drones, trucks, or boats, XT90 connectors provide the extra capacity and security you need.
Bullet connectors are great for custom setups, especially when you want modularity or easy swapping of components. Just be sure to use the right size and ensure solid soldering or crimping to avoid power loss or heat issues.
Final Tips
- Always match the connector current rating to your system’s maximum draw.
- Check polarity carefully to avoid damaging electronics.
- Use quality connectors and solder joints to prevent failures.
- Consider strain relief and secure mounting to avoid accidental disconnections during use.
Choosing the right connector might seem like a small detail, but it makes your RC projects safer and more enjoyable. Happy flying, driving, or sailing!
