An XT60 connector is a type of electrical connector used on RC (radio control) model aircraft and battery packs. It is a two-pin connector with a male and female side, each containing three gold-plated contacts. The XT60 was developed as an upgrade to the older style connectors, which were prone to melting and shorting out. The XT60 can handle up to 60 amps of current, making it ideal for use with high-powered brushless motors.
