Electrical Performance

• Continuous current: 30A

• Instant current: 35A

• Short-term current: 40A for 10 seconds

• Voltage range: 6V–16V

• PWM frequency: 8KHz

• Speed control curve for smooth throttle response

Battery Compatibility

• NiMH: 4–12 cells

• LiPo: 2–3 cells

• 4S LiPo supported, but BEC output must not be used

BEC Output

• Continuous output: 2A

• Instant output: 3A

• 2S LiPo: supports 4–5 micro steering gears
