QY OKW 2PIN FEMALE+XT90

QY OKW 2-Pin Female + XT90

The QY OKW 2-Pin Female + XT90 is a pre-assembled battery and charging connection accessory that combines an OKW-style 2-pin female connector with an XT90 power connector for use in compatible DC battery systems. It is designed for situations where a battery pack, charger, vehicle wiring harness, or test setup uses two different connector standards and a ready-made interface is preferred over fabricating a custom adapter from individual parts.

The product is particularly relevant to lithium battery assembly and electric-mobility servicing, where XT-series connectors are commonly used on battery-side or power-side wiring and 2-pin charging sockets or couplers may be used on the enclosure or charger interface. By combining both connector formats into one assembly, the adapter can simplify replacement, servicing, prototyping, and production wiring when the electrical specifications and pinout match the intended system.

Technical Details

The assembly acts as an adapter between the mating XT90 connection and the mating 2-pin female/plug system. Electrical power passes through the two conductors when both connectors are fully seated and the wiring has been matched correctly for polarity.

The connector assembly itself does not regulate voltage, limit charging current, balance cells, or protect the battery from electrical faults. Those functions belong to the charger, BMS, fuse, controller, or other protection components in the system. For this reason, the adapter should be chosen as part of the complete electrical design rather than treated as a universal charging accessory.

Confirm the exact OKW 2-pin mating connector, XT90 gender, polarity, conductor size and system current before installation. Connector names can vary among sellers, so physical keying and terminal arrangement should be compared with the actual battery or charger. The safe current of the finished assembly depends on the complete current path, including both connector types, wire size and joints. If used as a charging lead, charger voltage and charging profile must already be correct for the battery chemistry and series count.

Applications

When compatible with the equipment, this connector assembly can be used in:

• Lithium-ion and LiFePO4 battery pack wiring

• Electric scooter and e-bike battery systems

• Charger-to-battery connection leads

• Battery enclosure charging interfaces

• Battery assembly and repair workshops

• DC power test setups

• Portable power systems

• Solar or backup battery installations

• Custom EV and battery harness projects

Application suitability depends on the connector pinout, wire and terminal capacity, system voltage, operating current, and mechanical installation.

Installation Guide

Check continuity and polarity before connecting the assembly to a live battery. Make sure both connectors seat fully and that the wire is not pulled sideways or sharply bent at the terminal exit. In battery boxes and vehicles, provide strain relief so vibration and movement are not transferred directly to the electrical joints.

If the adapter is being used as a charging interface, ensure that the charger voltage and charging profile are correct for the battery chemistry and series count. This cable only makes the electrical connection; it does not make an incompatible charger safe.
