1. As a common boost-and-drop power supply with over-voltage/over-current/over-power/over-temperature/under-voltage protection
2. The product has constant current function and can charge all kinds of small rechargeable batteries within 0.6V-30V within 15W.
3. This product has constant current function, can directly drive 0.6-30V, 0-15W LED lamp
4. This product can adjust the constant current value (between 0 and working current) to achieve LED polar dimming, no stroboscopic!

Charging step:
(1) Determine the floating charge voltage and current of your rechargeable battery; (If the lithium battery parameter is 3.7V/2200mAh, the floating charge voltage is 4.2V, if it is 12V rechargeable battery, the floating charge voltage is generally set to about 14V)
(2) Under no-load condition, set the output voltage to reach floating charge voltage; (If charging 3.7V lithium battery, adjust the output voltage to 4.2V only)
(3) Set charging current (constant current value) and set current directly. Note: When setting the current, the power should be calculated, charged within the power range, and the product will enter a protective state if it is used with super power.
(4) Connect the battery to charge
Step of driving LED lamp:
(1) Determine the working current and maximum operating voltage of the LED you need to drive.
(2) Under no-load condition, set the voltage and current values to make the output voltage reach the maximum working voltage and working current of the LED.
(3) Connect the LED and test it.
