High-Current Battery Connectors from China
1 resources tagged with "High Current"
High-current battery connectors — XT30, XT60, XT90, Anderson Powerpole, and EC3/EC5/EC8 — carry anywhere from 15A continuous on an XT30 to 90A+ on an XT90, so contact resistance and gold-plating quality matter more than price. The dominant genuine brand is Amass, and the China market is full of visually identical clones with thinner plating that overheat under sustained load. When we source these, the single most useful incoming check is a milliohm-meter reading on the mated pair; genuine XT60 contacts typically measure in the low single-digit milliohm range.
High-current connectors are the power-path interconnects between a pack and load (drones, e-bikes, RC, battery storage). The common pitfall is buying clone XT/EC connectors that meet the form factor but not the current rating — they pass a visual check, then sag voltage and char under real current, so spec genuine Amass and verify contact resistance.

FAQ
How do I tell a genuine Amass XT60 from a clone?
Genuine parts have crisp laser-etched Amass branding, consistent gold plating on the contacts, and contact resistance in the low single-digit milliohms. Clones often have dull or partial plating, looser fit, and noticeably higher resistance that you can confirm with a 4-wire milliohm meter.
What current ratings do XT30, XT60 and XT90 handle?
As a working guide: XT30 around 15A continuous, XT60 around 30A continuous (60A+ burst), and XT90 around 90A. Treat printed ratings as marketing and derate for sustained loads, especially with clone connectors.
What MOQ and lead time are typical for these connectors?
Standard XT/EC/Anderson connectors are stock items with low or no MOQ from distributors; custom wire-harness assemblies usually start around 500–1,000 pieces with a 2–4 week lead time.
