Use and over-current protection buck module Instructions: (1) Adjust the voltage potential so that the output voltage reaches the desired value. (2) Use a multimeter to measure the output short-circuit current at 10A stall, and adjust the current potentiometer so that the output current reaches the predetermined over-current protection value. (For example, the meter shows the current value of 4A, then you can use the modules maximum current 4A) (3) Connect to the load. Used as a charger Instructions: (1). Make sure you need to charge the battery float voltage and charge current; (if the lithium battery voltage is 3.7V / 2200mAh, the float voltage is 4.2V, the maximum charge current is 1C, ie 2200mA) (2). Under no-load conditions, adjust the voltage potentiometer so that the output voltage reaches the float voltage; (if 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V) (3). Use a multimeter to measure the output short circuit current and 10A stall, while adjusting the current potentiometer to lose its effect Product Details Product Size: 0.2 x 0.2 x 0.2 inch; 0.16 oz Shipping Weight: 0.3 oz
