For lithium ion battery:

When the lithiumion battery voltage is low, if directly with constant voltage charging, due to pressure difference is big, cause the charging current is too large, lead to battery damage, so start to use constant current charging the battery, when charging to a certain degree of automatic switch back to the constant voltage charging. For current charging curve as follows: Red for current, blue for the voltage.

This module is adjustable step-down module, can adjust the m odule above the blue star output voltage adjustable resistance to change. Input/output differential pressure is 1 V, the minim um can output voltage is 0.8 V.

★Taken the module indicated above IN - (input cathode), IN + (input negative),OUT - (output cathode), the OUT + (output negative) must be correct, otherwise may cause damage of module.

★ Taken the battery charging method of use:

1. Make sure you need to recharge battery float charging voltage and charging current, input voltage module;

2. Adjust the constant-voltage potentiometer, the output voltage regulation to around 5 v.

3. The output short circuit current is measured with a multimeter 10 a current block, and regulate the flow of constant potentiometer output current reaches a predetermined charging current value;

4. The lamp current charging the default delivery is 0.1 times the charging current (constant current value).

5. Adjust the constant-voltage potentiometer to output voltage float charging voltage;

6. Battery is connected, try to charge.

(1, 2, 3, 4, 5 steps for input power management module, the output light batteries!)

★ Taken the LED constant current drive method of use:

1. Make sure you need to drive the LED working current and maximum working voltage;

2. Adjust the constant-voltage potentiometer, the output voltage regulation to around 5 v.

3. The output short circuit current is measured with a multimeter 10 A current block, and regulate the flow of constant potentiometer output current to the expected LED working current;

4. Adjust the constant-voltage potentiometer to make the output voltage LED highest working voltage;

5. Plug in the LED, commissioning.

(1, 2, 3, 4 steps for input power management module, the output light leds!)

Please note that the input GND and output GND should not be connected together
