Amass XT90 Male / Female Battery Connector

The genuine Amass XT90 is the high-current step up from the XT60, used on large multirotors, cinelifters, big fixed-wing models and high-capacity battery packs. Its gold-plated brass contacts are moulded into a high-temperature nylon body, which keeps them aligned for easy plugging and unplugging. Choose a single male or female connector, with or without the housing.

Key features

• Amass rating of 45 A at a temperature rise under 85 °C, ahead of the XT60's 35 A
• 4.5 mm gold-plated brass contacts moulded in place for low contact resistance and consistent alignment
• Polarised body shape guards against shorting and reverse-polarity connection
• Takes wire up to 8 AWG, with semicircular solder terminals that make fitting the wire easier
• Housing versions (XT90H) add a cover over the solder joints that insulates them against shorts
