The ESC is not waterproof. You need to make it waterproof by yourself. (to apply glue), Support forward and reverse, no brake.ESC power plug is XT60 or T plug, The motor end plug is either a 4mm plug, a single plug (one for one), or a double plug (one for two).The ESC cable is 14AWG high temperature resistant silicone soft cable, high current copper wire.A total of 24 mos of high power in the front and rear.H bridge, each road lower arm has 6 high power mos.The forward and reverse power is the same, and it is not a design that reduces the reverse output power.The actual maximum value of continuous current for forward and reverse rotations is 100A, and the rated power of the ESC is 1000W.640A 860A is just the brushed ESC label, not the actual current value, no real intention.Suggestion:12V voltage working condition: 3x540 or 3x550 OR 2x775 or 2x795 or 1x895 or 1x997 motor.24V voltage working condition: 2x775 or 2x795 or 1x895 or 1x997 motor.Dimensions: 7.2 x 3.5 x 2.4cmESC working voltage 10.5v-26vThe driver input pulse width is 0.8ms-2.2ms, 1.5ms is the midpoint.UBEC 5v 3A switch can drive two 25kg servos. It's not a 7805 linear regulator, so you can't use two ESCs to power the receiver at the same time.After power on, the led indicator flashes slowly for 3 times for self-test, and stable light after self-test means normal operation.If the throttle is not in the middle position when turned on, the LED will flash intermittently. Then you need to adjust the throttle position to midpoint and the ESC can work only when the LED is always on.If the throttle signal is lost and the LED blinks rapidly, the motor will stop.Water-cooled for remote control boatsColour:blackMaterial:composite materialPackage Contents:1 * 860A speed controllerNote: If a receiver uses two ESCs at the same time, you need to cut off the red positive wire in the middle of the BEC signal wires of ONE ESC. One ESC can supply power to the receiver, and if two ESCs supply power to the receiver at the same time , it will burn.Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
