Description
Overview
An adapter lead with an XT90 male plug on one end and a 2+4 or 2+6 female charging socket on the other, on SM 2-pin contacts. Rated 45 A for lithium packs and new-energy power wiring.
Specifications
- Battery side: XT90 male head
- Socket side: 2+4 or 2+6 female
- Contact family: SM 2-pin plug
- Current rating: 45 A
- Variants: XT90 to 2 4 Female, XT90 to 2 6 Female
Purpose
A pack that leaves the factory on XT90 will not plug into an SM-pattern charging socket, and a soldered tail cannot be undone. This makes that junction pluggable in either common layout.
Applications
- E-bike and scooter charging inlets
- Bench chargers feeding an XT90 pack
- Capacity and cycle test rigs
- Retrofit ports on converted vehicles
How to Use
- Confirm the pack ends in XT90 male and note whether the charger takes a 2+4 or 2+6 socket.
- Seat the XT90 head fully without forcing it.
- Check polarity at the socket with a meter before connecting a charger.
- Add strain relief so pulling the lead does not load the solder joints.
- Caution: 45 A is the connector’s rating — stay under both pack and charger limits, and never mate it while the charger is energised.
