• Custom EV battery harnesses requiring 500A peak-rated connectors

Rated 110A–130A continuous, 500A peak. For systems requiring sustained loads above 130A, consider a higher-gauge solution. Compatible with standard QS8 ecosystem.

Overview

The QS8-S is the heavy-duty evolution of the QS8 connector — built for e-bike, e-moto, and high-performance drone applications where standard connectors simply can't keep up. With gold-plated 8mm bullet contacts, UL94 V-0 flame-retardant housing, and 8AWG silicone wire, this harness is engineered for sustained high-current operation without heat buildup or connector degradation.

Whether you're building a 72V e-moto battery pack, wiring a high-discharge drone, or upgrading an aging connector on your e-bike, the QS8-S delivers the current capacity and reliability your system demands.

Key Features

⚡ 110A–130A Continuous / 500A Peak
