Introduction

1.   Part description: 1pc 7-segments LED; 2pcs tact switch(on/down, off/up); 1pc 3.6mm DC block, port for this same charge and discharge; 1pc 5mm white LED.

2.   7.2V lithium protection function:8.5V over-charge protection; 3A over-current, short-current etc basic protection function.

3.     Intelligent 5-speed control: Constant power output.

 (1).Power on: Connect to the load, press the tact switch for a while, LED display the number ‘1’, it means successful start, output power 100%; decimal point flashing( that states: output voltage regulation, 5seconds after decimal point off, digital LED will display current battery).

(2)Adjust the output voltage decreases operation: press tact switch ‘DOWN’, LED displayed value increase, output voltage decrease, when minimum voltage output, LED displayed the number ‘5’.

 (3)  Adjust the output voltage increases operation: press tact switch ‘UP’, LED displayed value decrease, output voltage increase, when maximum voltage output, LED displayed the number ‘1’.

 (4) Indicate current battery: no key operation within 5s, digital LED will display current battery value: LED displayed number is ‘9’, it means current battery voltage is the highest; if displayed number is ‘1’, it means current battery is lowest.

 (5) Shutdown operation:

A.  Press tact switch “off” for a while, digital LED off, output off into standby mode; if white LED is lit this time, then need to turn off white LED first, then can off the output.

B.  Disconnect the load, automatically enter standby mode.

4.    Charge indicator: charging time LED displayed current electric quantity “1-9”, decimal point flashing;  after full of charge LED displayed number is ‘9’.

5.    Charger requirement: constant current and constant voltage, 8.5V/1.2A;

6.    Electric quantity indication: unconnected load condition, press any tact switch, LED will indicate current battery electric quantity. Release the button, LED off; electric quantity indicator value 1-9, 9 is the max number.

7.    Load: Purely resistive load, resistance: 4-100 ohms, can not connect the battery/motor/capacitance etc load.

8.  Operating current: <15mA; standby current:<40uA; output power: 16W MAX; power output efficiency: ≥98%.

9.   Load short-current indication: LED display “E”, this time need to take off output,  check the load.

10.  Illumination: press the bottom for 3seconds, the white LED light on/off.
