3.5mm connnector. Nylon, brass material. 24K gold plated.
It can bear bigger currents. 80A currents for more than 5 minutes. Usually it is used for R/C batteries, R/C cars etc. We have a patent for this product, so our XT60 is a original product.
It is very easy to solder the wire to this connector, no need to assemble the housing to metal plug, the connector is moulded. So it is better than EC3 connector.
