The XT30, known for its compactness and efficiency, and the Deans, recognized for its robustness and widespread use, are often the topic of debate among enthusiasts and professionals alike. Both connectors come with their unique set of benefits and potential drawbacks, making the choice far from simple.
This article seeks to delve deep into the intricacies of each, comparing their design, performance, suitability, and other vital aspects. By shedding light on these connectors’ features, we hope to provide readers with a comprehensive understanding, enabling them to make informed choices tailored to their specific needs.
Market Presence & Pricing
While the XT60, a member of the XT series, is widely regarded as a technologically advanced successor to the Deans, it’s crucial to note that many RC manufacturers still prefer the Deans due to its cost-effectiveness. This affordability makes the Deans plug a preferred choice for many, despite the rising popularity of the XT60 in various RC models and chargers.
Usability
XT30: Known for easy insertion and removal. Its soldering is also considered straightforward.
Deans: While it offers excellent performance, some users might find XT series connectors easier to handle, both in terms of soldering and plug-in/plug-out operations.

| Suitable RC Models | RC cars (1/16, 1/14 scale), RC planes under 1m wingspan | RC cars (1/8, 1/10 scale), RC planes over 1m wingspan |
| Popular Uses | Small drones, small RC planes, 250-size quadcopters | Larger RC cars, boats, large drones, larger RC planes |
Continuous Current Capacity
XT30: Designed to handle up to 30A of continuous current.
Deans: Built to manage around 60A, thanks to its larger contact area and gold plating, which means less resistance.
Burst Current Capacity
XT30: Can withstand short bursts of up to 40A.
Deans: Capable of short bursts ranging from 75A-100A.
Resistance and Overheating
Importance: Rated current is critical. The connector should handle the device’s maximum current draw without overheating. Overpowering motors or devices with high current draws can cause connectors to heat up, potentially leading to melting.
XT30: Suitable for devices with moderate power needs.
Deans: More suitable for high-powered devices due to their higher continuous and burst current ratings.
Mechanical Properties
Connector Type & Material
XT30: Gold-plated type made of gold-plated brass.
Deans: Flat, tab-style made of copper with either gold or tin plating.
Size & Suitable Uses
XT30: Small-sized. Ideal for small drones, RC cars (1/16, 1/14 scale), RC planes under 1m wingspan, and 250-size quadcopters. Most suitable for 2S and 3S LiPo batteries with capacities below 1500mAh.
Deans: Medium-sized. Perfect for larger RC cars (1/8, 1/10 scale), boats, drones, and RC planes with a wingspan over 1m. Best paired with 3S, 4S, and 6S LiPo batteries with capacities over 1500mAh.
Durability & Lifespan
Both connectors have a commendable lifespan, enduring over 1000+ cycles. However, in terms of temperature resistance, Deans slightly outdoes XT30, withstanding temperatures ranging from -20°C to 150°C, compared to XT30’s -20°C to 120°C.
Conclusion
In choosing between XT30 and Deans, users need to consider their specific needs, the power draw of their devices, and their budget. While the Deans might be suitable for more high-powered applications due to its superior current capacity, the XT30 (and by extension, the XT60) offers ease of use that many find appealing. No matter the choice, ensuring the connector’s compatibility with the intended use is paramount.
FAQs of XT30 and Deans Connector
Q: Is the plug getting hot due to excessive current?
Answer: Yes, that’s one possible reason. Overcurrent can cause connectors to overheat because as current flows through the connector, resistance can generate heat. However, another reason might be a poor solder joint, sometimes referred to as a “cold solder joint”. This can create additional resistance and localized heating.
Q: How can the durability of connectors be improved?
Answer: Avoid overheating. If your connector is getting hot, it is an indicator that there might be too much current flowing through it for its design specifications. Over time, excessive heat can degrade the materials and performance of the connector. To ensure longevity, you should consider replacing it with one that is rated for a higher current capacity. It’s also crucial to ensure proper installation and secure connections to reduce the likelihood of issues like cold solder joints.
Q: Is it correct to pull the connector by the wire when disconnecting it?
Answer: No, it’s not advisable. Pulling the connector by the wire can stress the connection point, potentially leading to wire breakage or damage to the connector itself. This can cause the connector to fail prematurely or even create a potential hazard. It’s always best to grip the connector’s body when plugging or unplugging, ensuring that the force applied is directly on the connector and not on the wire.
