This is the 72V version of the QS-S4 trigger throttle and LCD suitable for the Zero 11X
Connection Type: 6-pin round waterproof plug - MALE CONNECTOR.
USB Port
The QS-S4 also features a USB port that can supply 5V at around 500 mA to 1000 mA of current. It’s primarily intended for flashing the unit, but it could potentially be used for charging USB accessories though we do not advise it as current-thirsty USB devices risk frying your throttle unit.
