Description
XT90 High-Current Battery Connector
XT90 two-pole connector for battery and DC power wiring. Select the brand and connector type (male or female). The listing offers Amass and Generic versions; materials and ratings can differ between variants.
🔧 Product-listing specifications
- Connector family: XT90
- Variants: Amass or Generic; male or female
- Maximum operating voltage: listed up to 500 V DC; confirm the exact part’s datasheet and system requirements
- Contact resistance: listed as ≤0.5 mΩ (source figure)
- Amass material listed: PA66, UL94 V-0; gold-plated brass contacts; listed heat resistance to 105 °C
- Generic material listed: polypropylene/PA6, UL94 HB; tin-plated contacts; listed heat resistance to 80 °C
- Approximate dimensions: 21 × 16 × 8 mm per connector
- Mounting: solder to suitably sized wires or PCB using the angled terminals, depending on the selected variant
⚠️ Current rating—important
The source listing describes 90 A as continuous current. However, an Amass manufacturer datasheet for certain XT90-H connectors lists 45 A rated current and 90 A momentary current. Do not treat 90 A as a continuous rating. That datasheet applies only to the exact Amass model it covers; confirm the model suffix and the rating of the selected connector. The Generic option is not covered by that Amass datasheet. Safe current also depends on wire gauge, soldering, contact condition, temperature, and the installation.
🔌 Polarity and connection
The source’s polarity description (“centre = +, body = −”) is ambiguous for this two-contact connector. Identify positive and negative from the molded markings and the exact connector/wiring diagram; do not infer polarity from the shell or connector gender. Match positive to positive and negative to negative, and check continuity and for shorts before connecting a battery.
💡 Typical applications
- Battery connections for drones and multirotors
- LiPo packs for e-bikes, scooters, and RC models
- Portable UPS and inverter battery systems
- DC-DC converter and power-management prototypes
- Robotics and other DC battery-powered equipment
🛠️ Soldering and safety
Disconnect the battery and all power before soldering. Use a soldering iron suitable for the connector and wire, avoid overheating the plastic housing, insulate each joint with appropriate heat-shrink tubing, and verify polarity and isolation before energizing. High-current battery wiring can cause severe burns, fire, or equipment damage if shorted. Use a correctly rated fuse and wiring appropriate to the actual load.
