Quick Selection Guide

  • RC Racing / Drones: Choose XT90-S — anti-spark design protects your ESC and battery on first connect
  • Electric Motorcycle / E-Moto Builds: Choose AS150 (high current) or Anderson SB50 (charging applications)
  • E-Bike / E-Scooter Charging Port: Choose M23 — IP67 rated, safe for outdoor and wet conditions
  • Adapting Between Different Connector Types: Choose QS8 to XT90 Adapter Cable
  • Full Vehicle Lighting Wiring: Choose from the Custom Wire Harness series

Frequently Asked Questions

What is the difference between XT90 and XT90-S?

The XT90-S features a built-in anti-spark resistor that prevents arcing caused by capacitor inrush current on first connection. It is strongly recommended for large-capacity battery packs.

What does IP67 waterproof mean?

IP67 means the connector can withstand temporary immersion in water up to 1 meter deep for 30 minutes. Suitable for outdoor, rainy, or high-humidity environments.

How do I know if a connector's current rating is sufficient for my system?

We recommend choosing a connector rated at least 20–30% above your system's peak current draw to ensure a safe operating margin.

Warranty & Returns FAQs

A: All standard wire harnesses sold via our Shopify store come with a 12-month standard warranty covering manufacturing defects, terminal crimping failures, and IP-rating compromises under normal use.

A: Because custom harnesses (from 1-piece prototypes to OEM batches) are built exclusively to your specifications, they are non-refundable. However, if the product fails to meet the agreed-upon CAD drawing or fails our 100% continuity test, we will rework or replace it free of charge.

A: We offer a 30-day hassle-free replacement for standard products. Please submit a ticket with your Order ID and a clear photo of the damage, and we will ship a replacement within 24 hours.

A: For applications exposed to harsh environments, please provide photos showing the installation context. Our engineers need to verify that the cables were routed correctly to validate the warranty claim.
