The ZTW ESC allows you to program your esc for many functions. Select the battery type, RMP limits, Start (normal, soft, or very soft), Brake, Timing (Auto, 7-22, 22-30), Rotation, LVC (2.8V per cell, 3V per cell, 3.2V per cell), and how the LVC is activated (total power cut to motor, or reduce RPM's with power to land).
