XT Series Connectors
If you’ve ever dabbled in FPV drones, RC planes, or DIY electric vehicles, you’ve undoubtedly seen those iconic yellow plugs. While they might look like simple pieces of plastic and metal, XT Series connectors are the unsung heroes of the hobbyist world, acting as the reliable “heartbeat” between your battery and motor.
In this post, we’ll break down why these connectors became the industry standard and which one you should choose for your next project.
Why XT Connectors Rule the Market
Before the XT series (developed by Amass), the community relied heavily on Deans (T-plugs). However, XT connectors took over for several key reasons:
- Safety First: Their “sheathed” design means there are no exposed conductive parts, significantly reducing the risk of accidental short circuits.
- Gold-Plated Efficiency: They use high-quality gold-plated banana plugs, ensuring low resistance and high conductivity.
- Heat Resistance: Made from high-temperature Nylon, these plugs won’t melt the moment you touch them with a soldering iron.
- Ergonomics: The textured grip and asymmetrical shape make them easy to plug in and impossible to reverse polarity (anti-spark versions are also available).
Meet the Family: XT30 vs. XT60 vs. XT90
Choosing the right connector is all about balancing weight and current (Amps).
- XT30: The Micro Specialist
- Continuous Current: 15A (30A Burst)
- Best For: Micro quads (Whoops/Toothpicks), small RC planes, and lightweight robotics.
- Why use it? When every gram counts. It’s tiny but far more reliable than the older JST connectors.
- XT60: The Universal Standard
- Continuous Current: 30A (60A Burst)
- Best For: 5-inch FPV drones, 3D printers, and mid-sized RC vehicles.
- Why use it? It is the “Goldilocks” of connectors—not too big, not too small, and capable of handling the power needs of 90% of hobbyist projects.
- XT90: The Heavy Hitter
- Continuous Current: 45A (90A Burst)
- Best For: Large scale cinematography drones, electric skateboards, and high-voltage e-bikes.
- Pro Tip: Look for the XT90-S version. It features an integrated Anti-Spark resistor that prevents that scary “pop” sound when connecting high-voltage batteries (6S and above).
Comparison Table
| Model | Recommended Wire | Max Steady Current | Common Application |
| XT30 | 18 – 22 AWG | 15A | Ultralight Drones / Small Electronics |
| XT60 | 12 – 14 AWG | 30A | Standard FPV / Desktop DIY |
| XT90 | 8 – 10 AWG | 45A – 60A | Large UAVs / EV Prototypes |
Pro Tips for Soldering XT Connectors
Soldering these can be tricky if you’re a beginner. Here are three “Golden Rules” to keep your build clean:
- The “Mate” Trick: Always plug a male and female connector together while soldering. This acts as a heat sink and keeps the internal pins perfectly aligned if the plastic gets too soft.
- Tin Everything: Apply solder to both the wire and the connector cup before trying to join them.
- Heat Shrink is Mandatory: Never leave the solder joints exposed. Use high-quality heat shrink tubing to insulate the connection and provide strain relief.
Final Thoughts
The XT series has earned its reputation through reliability and ease of use. While there are newer connectors on the market (like the MR series or AS150), the XT30, XT60, and XT90 remain the king of compatibility.
