The smart start-stop technology is introduced to the Max10 G2 ESC. The frameless fan will not be enabled to reduced noise and saving power. The fan will only work when the temperature rises to a certain level.Compared with the previous generation of the MAX10 ESC, the total capacitance of the capacitor is increased by 74% and is overheating protected. Smart freewheeling technology enables the MAX10 G2 to have higher drive efficiency than the previous generation, resulting in lower operating temperatures and a minimum temperature of approximately 25C lower than the previous generation. After connecting the ESC with the OTA Bluetooth module, you can view the data (throttle amount, voltage, current, temperature, speed and etc) in real time through the mobile app to know the running status; The history of the running status can also be viewed by data logging.
