QS8 Male/Male Connector

High current QS8 Male DC connector for powerful e-mobility systems: e-bikes, e-motorcycles (Sur-Ron, Talaria, etc.), go-karts, RC and DIY. The 8 mm contacts ensure very low transient resistance and stable operation under high loads.

Customization

• Connecting the battery to the motor controller
• For fast charging and high current adapters (depending on charger specifications)
• Upgrade projects where high A-reserve and reliability are required

Benefits

• Very high current capacity – up to ≈200 A continuous*
• Key geometry – protection against false polarity
• Robust PA/nylon housing construction, vibration resistant
• Convenient soldering “buckets ” – quick and clean installation

* The actual current depends on the cross-section of the wire, the length, the cooling and the quality of soldering.

Specifications

• Type: QS8 Male, 2 pin DC
• Contact diameter: ~8 mm
• Rated current: ≈200 A (continuous), short-term peaks – higher (according to installation)
• Recommended wire: 6-8 AWG (select according to current and length)
• Contacts: gold-plated copper alloy
• Housing: heat-resistant PA/nylon material
• Anti-spark: no (this version without anti-spark; anti-spark – QS8-S)
• Quantity: 1 pc. ( QS8 Female pair – purchased separately)

Installation tips

• Strictly observe polarity (+/-) and pinout.
• Use a powerful soldering iron, short heat; apply heat-shrink after soldering.
• For high currents, choose a thicker cord and shorter route; leave the tension loop.

FAQ

Is it suitable for fast charging?
Yes, if the voltage/current and the cross-section of the wires meet the requirements.

How is the QS8 different from the XT90?
The QS8 has larger contacts (8 mm) and is designed for higher currents (lower losses under load).

The anti-spark function is needed. What to choose?
Choose the QS8-S (anti-spark) version or use an external pre-charge solution.
