Scheme features
1. Three lithium batteries are used for power supply. Long press and soft touch the button for 1.5 seconds to start the machine. When long press and hold, the green LED indicator will be on for a long time. The blue LED indicator will light up from the first grid to the fourth grid one by one, and the machine will start after the fourth grid is on.
2. The first gear is the default when power on, the green LED indicator is off, short press and touch the button to increase one gear at a time, the blue LED indicator is corresponding to the number of gears, the first gear is on, and so on,
Press the light touch switch, the LED indicator lights are all off, enter the standby mode, then press the light touch switch, enter the first gear, cycle in turn. Press and tap the switch again for 1.5 seconds to turn off the machine. When pressing and holding the key, the blue LED will turn off
The indicator light goes out from the fourth grid one by one. After the LED indicator light of single first gear goes out, the power is turned off.
3. When power on, the green LED indicator flashes rapidly (4Hz) to represent the power. Flash once below 11V, twice between 11v-11.7v, and three times above 11.7v, and display once every 5 seconds.
4. The red LED is always on when charging, and the green LED is always on when fully charged. Filling while using is not supported. When the machine is turned on for use, plug it in for charging and turn it off automatically. The charging current is 650ma
5. Low voltage protection, when the voltage is lower than 10V, it will shut down automatically. When it is lower than 10V, it cannot be started, and the red light will flash to ensure that the battery will not be over discharged. If it is not used for a long time and the battery is lower than 10V, it will be stopped
Charging can be activated normally.
6. Motor locked rotor protection, over-current protection current is 5A.
7. The quiescent current is less than 20ua
