Parameters:
9V battery version:
Output: 5V/7V/9V (3rd gear version)
Charging input: 5V 1A Micro USB
Motor: 9V version OUT (output) 5V-1, 7V-2, 9V-3 (+- error 1V) within 0.5A, overload heating
Charging: IN (input) 5V–0.9A
Independent charging management 4056 power management chip (charging heat is a normal phenomenon)
Battery: IN (input) 3V-4.2V (protection below 3V) Flashing running light reminder when less than 3.2V
Charging light: Red light on when charging, green light on when fully charged (2-light version compatible with running light)
If the output driving current exceeds 0.1-0.6A, the heating voltage will decrease or the protection shutdown will occur. Do not overload.
Standby current: 0.3uA (minimum), basically without power consumption. The battery has anti reverse connection design, output short circuit protection, and low battery protection.
9V plug-in power supply version:
Micro USB input voltage: must be 5V 2A
Power: 7W
Drive current: 0.5A
Motor: 9V version OUT (output) 5V-1, 7V-2, 9V-3 (+- error 1V) within 0.5A, overload heating
12V battery version:
Output: 6V/9V/12V (3rd gear version)
12V, 1st gear version, direct 12V, off 0V
Charging input: 5V 1A Micro USB
Motor: 12V version OUT (output) 6V-1, 9V-2, 12V-3 (+- error 2V), within 0.5A, overload heating
Charging: IN (input) 5V–0.9A
Independent charging management 4056 power management chip (charging heat is a normal phenomenon)
Battery: IN (input) 3V-4.2V (protection below 3V) Flashing running light reminder when less than 3.2V
Charging light: Red light on when charging, green light on when fully charged (2-light version compatible with running light)
If the output driving current exceeds 0.1-0.6A, the heating voltage will decrease or the protection shutdown will occur. Do not overload. 12V 0.5-0.6A maximum output power of about 7W
Standby current: 0.3uA (minimum), basically without power consumption. The battery has anti reverse connection design, output short circuit protection, and low battery protection.
Product size:
Main board size: approximately 24.52mm * 23.87mm
Hole diameter: 2.5MM
Plate thickness: 1MM
Gear logic:
Press button 1 for 1st gear, 2 for 2nd gear, 3 for 3rd gear, and 4 for shutdown Loop.
7W version running light:
Flash once in first gear;
Flash twice in second gear;
Flash 3 times in 3rd gear;
Below 3.2V, a flashing prompt will appear, and below 2.8V-3V, it will shut down.
3W version running light:
1st gear red light; 3rd gear blue light; Plug in the G, B, R colors for the model. If it is below 3.2V, a flashing prompt will appear, and if it is below 2.8V-3V, it will shut down.
Instructions for use:
*If the positive and negative poles are not aligned, it is necessary to switch them. The spacing between sockets is 2.0mm, and changing the direction of the plug can easily solve the problem of inconsistent polarity.
*The battery model must work with a battery, and the charging port only provides charging of 5V 1A
*The battery is a 3.7V lithium battery that can be used above 1000mA.
