QS anti-spark battery connectors
Two-pole and multi-pole battery connectors built around an anti-spark contact sequence, for drone packs, e-bike batteries, energy-storage racks and battery-swap cabinets. The current rating and the housing protection class pick the family; the termination picks the part inside it.
Nine families, one contact system
The range runs from QS2 and QS5 at the small end through QS6, QS7, QS8, QS9 and QS10 to QS12 and QS13, with suffixed variants inside each family. Rated current spans 45 A to 350 A and rated voltage is DC 500 V on the high-current families, AC 125 V on the mains-style ones. Because the families share a mating concept rather than a single shell, the plug and socket of one family only mate with each other — the family name is the first thing to fix, not the cable size.
The anti-spark sequence
These are not plain butt-joint connectors: the contact geometry sequences the connection so the inrush current of a capacitor bank or a controller does not arc across the main contacts at the moment of mating. That is the reason a QS part is specified on a battery lead rather than a generic two-pole plug, and the reason the male and female halves are sold as matched parts rather than interchangeable ones.
Housings, contacts and termination
Housings are PA66 with a UL94-V0 flame rating and operate from −20 °C to +120 °C. Contacts are gold-plated copper or gold-plated brass depending on the family, and termination is soldered or crimped. Ingress protection is family-dependent and is stated per part — IP65 on the sealed versions, IP52, IP40, IP30 or IP20 where the listing publishes a lower figure. No single IP number covers the range, so the protection class has to be read off the exact part.
Every model in this family, side by side
70 parts across 51 models, one row each. Sealing, contact count and electrical rating are exactly as published on the part page; a cell is blank where the listing does not state the figure. Prices are USD per piece, EXW Yueqing, lead time 10–20 days.
