The XT150 female connector is a high-current DC connector built for demanding e-mobility and RC power systems. It fits e-bikes, e-motorcycles such as Sur-Ron and Talaria, electric scooters, go-karts, UTVs and custom DIY builds. The connector carries 2 contacts and a nominal continuous rating of roughly 150 A.
This is the socket half of the mating pair. In other words, you solder it yourself onto your power cable. The matching XT150 male plug is sold separately. Therefore this connector suits anyone assembling a power bus from scratch rather than buying a finished harness.
Contacts are made from gold-plated copper alloy, while the housing uses heat-resistant PA nylon. The large contact area keeps contact resistance low. As a result, the connector runs cooler and stays stable even under very heavy loads. Two colours are available, black and red, and the colour is used to mark polarity.
Key Benefits
- Very high current capacity – rated in the 150 A continuous class for demanding battery runs.
- Low contact resistance – less heat build-up and smaller voltage drop along the power path.
- Larger contact area than XT90 – more current capacity where loads climb into the extreme range.
- Gold-plated contacts – a stable electrical connection across the full service life of the connector.
- Heat-resistant PA nylon housing – the body holds its shape at high current levels.
- Rugged construction – resists vibration as well as frequent mating and unmating cycles.
- Colour-coded polarity – black or red makes correct installation easier to verify.
- Wide wire range – accepts 8–10 AWG cable for heavy-gauge power leads.
Who Is This Connector For?
The XT150 female connector is intended for electric motorcycles, including the Sur-Ron Light Bee, Talaria Sting, Talaria MX3 and Talaria MX4. Beyond that, it serves electric bikes, electric scooters, go-karts and UTV machines. It is also used in RC models and in independent DIY builds.
The main application is the battery-to-controller power bus. In addition, the connector works in fast-charging or high-current adapters whenever the charger specifications allow it. Battery builders also reach for it wherever a 150 A class rating is required.
This part is aimed at experienced builders, battery assemblers and e-mobility workshops. Installation calls for a soldering iron and heat-shrink tubing. Consequently, it is not the right choice for anyone looking for a ready-made wiring loom.

Why Choose the XT150 Female Connector?
XT150 is the largest connector in the XT series. Compared with XT90, it offers a noticeably larger contact area. That translates into higher current capacity and lower losses under very heavy loads.
Gold-plated copper alloy contacts hold their low resistance even after many mating cycles. Meanwhile, the heat-resistant PA nylon housing withstands the heat generated at 150 A class currents. The body also resists vibration, which makes it suitable for chassis-mounted wiring looms.
Installation Tips
- Follow polarity (+/−) and pinout strictly before you solder anything.
- Use a powerful soldering iron and keep heating time short.
- Slide heat-shrink tubing over the joint once soldering is finished.
- Choose thicker wire and a shorter routing path for very high currents.
- Leave a strain relief loop in the cable near the connector.
Frequently Asked Questions
Does the XT150 female connector have an anti-spark function?
- No, this connector has no spark protection built in.
- If you need anti-spark, use connectors with a pre-charge solution such as the QS or XT90-S family.
- An external pre-charge circuit is another workable alternative.
Which models and machines is this connector suitable for?
- Electric motorcycles including Sur-Ron Light Bee, Talaria Sting, Talaria MX3 and Talaria MX4.
- Electric bikes, electric scooters, go-karts and UTV vehicles.
- RC models and custom DIY power builds.
Will an XT150 connector fit a Sur-Ron or Talaria power bus?
- Yes, the main application is the battery-to-controller power bus on these machines.
- The 150 A continuous class covers demanding high-load riding.
- You solder the connector onto your own cable, so the fit depends on your build.
What wire size should I use?
- 8–10 AWG cable is recommended for this connector.
- Thicker wire helps when you run currents near the 150 A class.
- Shorter cable routing reduces voltage drop across the run.
Is the male connector included?
- No, one female socket is supplied per order.
- The mating XT150 male plug is purchased separately.
- Choose your colour, black or red, to mark polarity on each side.
How does XT150 compare with XT90?
- XT150 has a larger contact area than XT90.
- That larger area gives higher current capacity under extreme loads.
- Losses stay lower because contact resistance is reduced.
How is the connector installed?
- Installation is by soldering, so a soldering iron is required.
- Heat-shrink tubing finishes and insulates the joint.
- Ready-made harnesses are not part of this product.
Choose your colour, black or red, and note it in the order comment. Each order includes one XT150 female socket with gold-plated copper alloy contacts and a heat-resistant PA nylon body. Pair it with an XT150 male plug to complete your 150 A power connection.
