Details

Upgrade a 2–4S whoop build with a firm Amass XT30 power lead for a clean, secure battery connection.

An integrated 25V 220uF capacitor helps reduce voltage spikes that can stress or damage the ESC during hard throttle changes.

The compact 65mm (2.1 in) lead fits tight whoop frames while keeping the XT30 connector easy to access.
