Plugs for the heavy-current side of an electric vehicle: battery leads, controller inputs and motor phases. Pick from the compact XT30 for small auxiliary branches up to the QS10 for Sur-Ron, Talaria and other e-moto builds, plus MT60 three-pin plugs for motor phase wires and RCPROPLUS 6808 D6 plugs that match the factory Light Bee X connector.

Current ratings at a glance
These are approximate ratings; what a joint really carries also depends on wire size and cooling.
- XT30: around 30A continuous, for lights, small modules and auxiliary lines.
- XT60: around 60A continuous, for e-bike and scooter batteries and DIY packs.
- XT90 and XT90-S: the larger two-pole XT plug, with the S version adding anti-spark.
- XT150: around 150A continuous, for e-motorcycles such as Sur-Ron and Talaria.
- QS8: 8 mm contacts and around 200A continuous.
- QS10: a bigger contact area than the QS8, for lower contact resistance at very high current.
- MT60: three pins for the phases of a brushless motor, around 60A short-term.
Fitting tips
Leave headroom between the connector rating and your peak current, and use wire thick enough for it. The XT30, XT60, XT150 and QS8 have gold-plated copper alloy contacts in heat-resistant nylon housings. QS8 and QS10 take soldered or crimped wires, while the RCPROPLUS plugs are soldered. Insulate every joint with heat shrink and check polarity before you connect a pack. Rather not solder a heavy lead yourself? Our workshop repairs battery packs, connectors and wiring in Kaunas.

Frequently asked questions
XT90 or XT150: which should I use?
Go by current. The XT150 is rated around 150A continuous for e-motorcycle battery leads, and the XT90 is the smaller step for builds that draw less. On high-voltage packs, consider the anti-spark XT90-S.
What is the difference between QS8 and QS10?
Both are two-pole high-current plugs. The QS10 has a larger contact area than the QS8, which means lower contact resistance and less heating under heavy load.
Can I crimp these connectors instead of soldering?
The QS8 and QS10 accept soldered or crimped wires. The RCPROPLUS 6808 D6 plugs are soldered. Each product page states the method.
What are MT60 connectors for?
Joining a three-phase brushless motor to its controller. One MT60 carries all three phase wires and handles around 60A short-term, depending on wire size and cooling.
