Frequently Asked Questions
What current rating does the AS150UPB-M support?
The AMASS AS150UPB-M connector supports continuous current up to 150A with proper wire gauge, making it suitable for high-power drone and RC applications using 6S-12S LiPo batteries.
What is the integrated signal pin for?
The signal pin provides battery voltage or temperature sensing feedback to the flight controller or ESC, enabling real-time battery monitoring without separate balance lead connection.
What wire gauge should I use?
For 150A continuous current, use 8AWG silicone wire. For 100A applications, 10AWG is sufficient. Ensure proper wire gauge to minimize voltage drop and heating at the connector.
Is there a matching female connector?
Yes, the AS150UPB-F female connector is the matching receptacle. We supply both male and female connectors and pre-assembled cable sets for common drone power configurations.
Can this replace XT90 connectors?
Yes, the AS150UPB offers higher current capacity (150A vs 90A) and lower contact resistance than XT90, making it a superior upgrade for high-power drone builds above 6S.
