Note:
1) PWM of Fulcrum Pro and Pro+ 300A ESC is 8KHz, which is not programmable.
2) Parameters with asterisk behind are the factory default settings of Fulcrum Pro/Pro+ 300A ESC.
3) When ‘LVC’ of ESC is set at ‘Auto’, the motor will emit beeps to detect the number of Lipo cells after
the two power beeps, and the red LED on ESC will blink in accompany with the beeps.
‘3.0v’ is the default cut-off
voltage of per Lipo cell when the LVC is set at ‘Auto’ detect.
For example: If connect ESC to a 4s Lipo battery pack, the motor will firstly emit

♪
, then detect
the Lipo numbers
♪
♪
♪
♪
, and the red LED will blink four times. The low voltage cut-off is
calculated as ‘12.0V’.
4) Please ensure only when the battery packs is fully charged and it can set the LVC at
‘Auto’
, it is
recommended to set the LVC at actual Lipo cells once the battery pack is over 4S cells.
