Frequently asked questions
Which battery voltage can I use with this ESC?
It supports 2S to 7S Li-Po packs. Each Li-Po cell is nominally 3.7 V, so the range is about 7.4 V to 25.9 V nominal (up to about 29.4 V when fully charged at 4.2 V per cell).
How do I wire it to a brushless motor?
Connect the three motor wires to the three phase wires of a brushless motor, and connect the battery to the power leads. If the motor spins in the wrong direction, swap any two of the three motor wires. Use this ESC only with brushless motors, not brushed DC motors.
