Battery charging methods:

1. Determine the float voltage and charging current that you need to charge battery and module’s input voltage.
2. Adjustable constant potentiometer, the output voltage is regulated to about 3V.
3. Use multimeter 10A current block measurement output short circuit current, meanwhile adjusting the constant current potentiometer to make output current reaches predetermined current value.
4. The charging turn lamp current default is 0.1 times of charging current (current value ).If you need, adjust turn lamp current potentiometer please (generally do not adjust).
5. Adjustable constant potentiometer to make the output voltage to the floating charge voltage.
6. Connect battery, to try charging (1, 2, 3, 4, 5 steps is the module input power, output no-load not connected to the battery).

LED constant current driving use methods:

1. Determine you need to drive LED operate current and maximum working voltage.
2. regulation constant potentiometer; 2, the output voltage is regulated to 3V.
3. Use multimeter 10A current block measurement output short circuit current, meanwhile adjusting the constant current potentiometer to make output current reaches LED operating current.
4. Adjustable constant potentiometer to make the output voltage to the LED maximum working voltage.
5. Connected to the LED, try test machine. (1, 2, 3, 4 steps is the module input power, output no-load not connected to the LED lamps).
