QS8-S Connector 8AWG 110A-130A High Current Harness for E-Bike E-Moto Drone Battery — Gold-Plated 8mm Bullet, UL94 V-0, 500A Peak | SLYT

The QS8-S is a heavy-duty, anti-spark battery connector designed for high-current DC power systems in e-mobility and UAV applications. It combines an 8mm gold-plated brass bullet contact with a built-in 5.1Ω anti-spark resistor that pre-charges ESC capacitors before the main power connection is made. The result? Zero sparking during battery connection — no pitted contacts, no damaged terminals, no unexpected ESC resets.

Compatible With

  • E-Bike battery packs (48V–72V systems, 110A–130A continuous)
  • Electric Motorcycles & E-Moto builds requiring high-current QS8-S connectors
  • FPV Drones & UAVs with high-discharge LiPo packs (8mm bullet compatible)
  • BMS (Battery Management Systems) with QS8-S output
  • High-current ESCs and motor controllers with QS8-S input
  • 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

Handles serious sustained loads that would overheat standard XT90 or QS8 connectors. The 500A peak rating provides headroom for motor inrush current spikes.

🔌 Gold-Plated 8mm Bullet Contacts

Large-diameter gold-plated contacts minimize contact resistance and heat generation at high current levels. Rated for 1000+ insertion cycles.

🔥 UL94 V-0 Flame-Retardant Housing

The connector housing meets UL94 V-0 flammability standards — self-extinguishing within 10 seconds. Critical for battery pack safety in enclosed EV applications.

💪 8AWG Silicone Wire

Heavy-gauge stranded tinned copper with ultra-flexible silicone insulation. Handles the current, stays flexible in cold, and resists heat from high-current operation.
