Specification: Item Type: Electric Speed ControllerMaterial: Plastic+AlloyColor: Red BlackSize: Approx. 60x45x45mm/2.4x1.8x1.8inWeight: Approx. 200.0g/7.1oz Continuous Current: 150A Maximum Current: 720A Motor Type: Sensorless and Brushless MotorFor lipo 4S or 12 nimh cells: 1. On-road: 40xx size or smaller engine, <3000kv kv2. Off-road/off-road vehicle/for monster: 40xx size or smaller engine with kv <2500kv For lipo 6s or 18 nimh cells: 1. On-road: 40xx size or smaller engine with kv <2500kv 2. Off-road/off-road vehicle/for monster: 40xx size or smaller engine with kv <2000kvResistance: 0.00030ohm Battery: 3-6 Cells Lipo / 9-18 Cells NIMH Bec Output: 6.1V or 7.4V/3A (Switch Mode) Fitment:Fit for 1/10 RC CarsFit for 1/8 RC Cars Instuction: 1. Connect BEC wires with the receive 2. Connect motor wires with ESC 3. Turn on the transmitter 4. Connect battery pack with ESC then switch on the ESC 5. When the connection of motor and battery is finished, the motor emits"beep-beep tone. 6. When the throttle stick is In the neutral position, the motor re-emits"beep-beep tone 7. The ESC is workable 8. 150A BEC voltage change: turn off ESC, connect the short circuit chip to bec, turn on ESC, and the motor will emit "beep". After 2 seconds, pull out the short circuit chip to the BEC. When the change of BEC voltage is completed, the motor beeps - "beep" (if be (the voltage is 6.1v, the motor beeps). If be (7.3v motor beeps twice), turn off BEC voltage change. Troubleshooting:1 . If after power on , motor can , t work , no sound is emitted，please check the connections between battery pack and motor . 2 . If after power on , LED flashes , please check the voltage of battery pack , which should be from （5V-25.5V） 3 . If the motor emits a " beep-beep " tone Only ( BEC voltage 6.1V ) or If the motor emits a " beep-beep " twice ( BEC voltage 7.3V ) , please check all the connections : BEC wires , transmitter andreceiver , throttle signal wires , etc . please check the transmitter TH . TRIM and adjust it to the motor re-emits Beep-beep tone 4 . If the car can't be speed up , please check either voltage of the battery pack is too low or the temperature of ESC is too high . If the voltage of the battery pack is too low , please replace the battery pack . If the temperature of ESC is too high , please check all connections . If not , please push the button EPA on your remote control 5 . If the car stops suddenly while in working state , please check the motor's connections , and the road 6 . If the car runs in the opposite direction , which the transmitter is available , please swap two wire connections between the ESC and the motor. Package List: 1 x Electric Speed Controller1 x Manual Note: 1. Manual measurement, please allow 1‑3mm/0.04‑0.12in error, thank you.2. Due to the difference between different monitors, the picture may not reflect the actual color of the item.3. Before using this ESC in water, please remove the cooling fan; clean and dry it immediately after use to prevent the connector from rusting.
