High-Current Battery Connectors: XT, Anderson, EC
1 resources tagged with "Battery Connectors"
For high-current battery work — RC, e-bikes, portable power — the connector families are XT30/XT60/XT90, Anderson Powerpole, and EC3/EC5/EC8, each rated by continuous current and contact resistance. Amass makes the genuine XT series, and clones are common: a real XT60 holds contact resistance low enough to stay cool at 60A, while a clone can heat up and melt under the same load. The number in the name roughly indicates the current rating (XT60 ≈ 60A continuous).
When you source high-current connectors, the spec that matters is contact resistance under load, not the rated amperage on paper. We check for genuine Amass markings and run a thermal test at rated current on a sample, since a hot connector is a fire risk.

FAQ
What current can an XT60 connector handle?
A genuine Amass XT60 is rated around 60A continuous (higher in short bursts). Clones often can't sustain that without overheating, so verify the contact resistance and run a thermal test at your real current.
How do I detect a clone XT or Amass connector?
Check for proper Amass branding, measure contact resistance with a milliohm meter, and thermal-test at rated current. Clones run hotter and have higher, inconsistent contact resistance that degrades over mating cycles.
