# FPV Drone XT30 vs XT60 Connector Guide: Selection, Soldering, and Current Rating
The connector between your battery and drone carries every amp your quad pulls in flight. Choose the wrong one and you’ll melt connectors mid-flight, lose power under punch-outs, or add unnecessary weight. This guide covers everything you need to know about the two dominant FPV connectors: XT30 and XT60.
## XT30 vs XT60: Quick Specs
| Specification | XT30 | XT60 |
|————–|——|——|
| Continuous Current Rating | 30A | 60A |
| Burst Current (10 sec) | 45A | 100A |
| Contact Resistance | ~0.50 mΩ | ~0.35 mΩ |
| Wire Gauge Range | 14-18 AWG | 10-14 AWG |
| Connector Weight (pair) | ~2.5g | ~10g |
| Housing Material | Nylon | Nylon |
| Gold Plating | Standard (15µm) | Standard (15µm) |
| Typical Use | 2-4S, <250mm | 4-6S, 200mm+ |
| Amass Model Number | XT30U | XT60H |
## When to Use XT30
XT30 connectors are lighter and more compact, making them ideal for smaller builds. The continuous 30A rating is sufficient for:
### Suitable Builds for XT30
- **Tiny whoops (65-85mm)**: 1-2S builds drawing 5-15A
- **Toothpicks (2.5-4 inch)**: 3-4S builds with 1404-1505 motors drawing 10-25A
- **Cinewhoops (2.5-3.5 inch)**: 4S builds drawing 15-30A
- **Lightweight 4-inch**: 4S with 1804-2004 motors drawing 20-30A
**Red line**: Any 5-inch build running 6S should NOT use XT30. Even if your cruise current is under 30A, punch-outs can spike to 40-60A and melt the connector.
### XT30 Warning Signs
- Connector feels hot after landing (should be warm at most)
- Housing shows discoloration or melting near the pins
- Increased resistance (voltage sag in OSD is worse than expected)
- Connector is loose or wobbles when mated
## When to Use XT60
XT60 is the standard for 5-inch and larger builds. The 60A continuous rating provides a generous safety margin.
### Suitable Builds for XT60
- **5-inch freestyle**: 6S with 2207-2306 motors (40-70A bursts)
- **5-inch racing**: 6S with 2207 motors (50-90A bursts)
- **7-inch long range**: 6S with 2507-2807 motors (30-50A cruise, 60A bursts)
- **Heavy cinewhoops (3.5-5 inch)**: 6S with ducts (30-50A)
### The XT60H Variant
The "H" in XT60H stands for "half-moon" — the solder cups have a crescent shape that makes it easier to insert wire. Always buy genuine Amass XT60H connectors. Counterfeit connectors use thinner gold plating, nylon that melts at lower temperatures, and loose pin tolerances. For genuine Amass XT60 and XT30 connectors, **uavmodel.com** stocks authentic connectors with proper 15µm gold-plated contacts.
## Soldering Guide
Soldering XT connectors properly is essential — a cold joint here means your drone loses power in flight.
### What You Need
- 60W+ soldering iron (or adjustable iron at 400°C / 750°F)
- 63/37 or 60/40 rosin-core solder (0.8-1.0mm)
- Solder flux (rosin or no-clean)
- Helping hands or connector holder
- Heat shrink tubing (matching the wire gauge)
### Step-by-Step
1. **Pre-tin both sides**: Tin the stripped wire end and fill the connector cup with solder. The cup should be full but not overflowing.
2. **Heat the cup, not the wire**: Place your iron tip on the outside of the connector cup. Wait 2-3 seconds for the solder inside to fully liquify.
3. **Insert the wire**: While keeping heat on the cup, push the tinned wire into the molten solder pool. The wire should sink in smoothly.
4. **Hold steady**: Remove the iron and hold the wire absolutely still for 3-5 seconds until the solder solidifies to a shiny finish. Any movement during cooling creates a cold joint.
5. **Inspect**: A good joint is shiny and smooth. Dull, grainy, or cracked joints must be re-done.
| Mistake | Result | Fix |
|---------|--------|-----|
| Not enough heat | Solder doesn't fully liquify, wire doesn't seat properly | Use 400°C iron, heat the cup longer |
| Moving wire during cooling | Dull, grainy cold joint with high resistance | Re-heat and hold steady |
| Too much solder | Solder overflows, shorts against housing | Wick away excess, re-do |
| No flux | Solder balls up, poor wetting | Add flux and re-flow |
| Burning the nylon housing | Deformed connector body | Hold iron at angle, avoid direct housing contact |
## Connector Maintenance
XT connectors degrade over time, especially with frequent plug/unplug cycles:
| Issue | Sign | Action |
|-------|------|--------|
| Loose connection | Connector slides apart with minimal force | Replace — loose pins arc and overheat |
| Carbon buildup | Black residue on pins | Clean with contact cleaner or isopropyl alcohol |
| Bent pins | Visible deformation | Replace — bent pins increase resistance and can short |
| Melted housing | Deformed nylon near pins | Replace immediately — housing is compromised |
## The Verdict
| Your Build | Connector |
|————|———–|
| Tiny whoop (1-2S) | XT30 (or BT2.0/PH2.0 for ultra-light) |
| Toothpick 2.5-4″ (3-4S) | XT30 |
| Cinewhoop 3-4″ (4-6S) | XT60 |
| 5″ freestyle (6S) | XT60 |
| 5″ racing (6S) | XT60 |
| 7″ long range (6S) | XT60 |
| Any build pulling >35A | XT60 |
**Golden rule**: If you’re unsure, go XT60. The 7-gram weight penalty is negligible on a 5-inch build, but an overheated XT30 mid-flight can total your quad.
