The QS8 high-current female connector is designed for connecting batteries and controllers in e-bikes, e-motorcycles and other high-power DC projects. The large contact area and anti-spark compatibility (with matching pair) help to reduce charging spark during connection.
Customization
- Battery output/input (e.g. for fast charging or power line)
- Controller power supply (high current DC bus)
- Conversion/Upgrade projects (Sur-Ron, Talaria, e-MTB, e-moto, etc.)
Benefits
- High current capacity – suitable for high loads and peak currents
- Reliable contact – low contact transient resistance
- Robust housing construction – resistant to vibration and frequent switching
- Polarity protection – “keying” before contact
Specifications
- Type: QS8 Female
- Contacts: 2-pole power connector (high current)
- Wire connection: soldering or pressing (depending on the nozzle used)
- Contains: 1 female connector (Male pair – sold separately)
- Current/voltage class: depends on the cross-section of the wire and the quality of the thermal installation (QS8 is often used with 6 AWG or similar wire)
Installation tips
- Use wires of appropriate cross-section (e.g. 6 AWG for high currents)
- Quality soldering/pressing and thermal insulation (heat-shrink)
- When first connecting the anti-spark pair – briefly apply pressure to the connector to settle the capacitors, then press all the way in
- Always observe polarity and safety requirements
FAQ
Does this connector have an anti-spark function?
The QS8 family of connectors can be available in an anti-spark version – the effect is achieved when paired with the appropriate plug (Male). Please check the specific model/batch.
Is it suitable for fast charging?
Yes, the QS8 is often used for fast charging and high currents if it meets the requirements of the wiring and charger.
What is the recommended wire?
Common practice is 6 AWG for high currents; choose according to current and length loss.
