Feature:1. The ESC is forward and reverse, forward 100% throttle, backward 100% throttle, middle 1500US, pulse width range, 1000US1500US2000US.2. Support 36S, the highest voltage is 25.2V, the ESC does not have a brake, and it is directly reversed.3. When the current is maintained at 15A, the temperature of the bare board of the ESC is about 70.4. The temperature is about 40 with the heat sink, which can continue to work for a long time.5. Used for 2838 underwater propellers, and also suitable for users to build the ESC in the sealed cabin of the propeller.Specification:Item Type: Brushless ESCMaterial: Electronic ComponentColor: BlackProduct Diameter: Approx. 29.1mm/1.1inProduct Thickness: Approx. 4mm/0.2inWeight: Approx. 5.0g/0.2ozContinuous Current: 15AMaximum Current: 30ASupport Battery: 3-6S (Maximum Voltage 25.2V)ESC:1.
