18650 Low-Power Lithium Battery Polymer 12V 4-Segment Battery Indicator Indicator Board is a battery power detection display board with buttons to realize the on-off function. Low power consumption state in shutdown state. Hw-798-b-1 is a series of lithium battery detection. The product is equipped with a key. After a short press, it will start and display the current power, and it will shut down after 5 seconds. Long press the button for more than 2 seconds in the off state to turn on and display the current power, and turn off after 5 minutes. Power on state, you can directly shut down through the button.
The algorithm of power filter and the algorithm of eliminating chattering at a critical point of the conversion between adjacent lamps are programmed. For a single lithium battery, for example, the turning point voltage of 3-grid lamp and 2-grid lamp is 3.75V. If the voltage happens at this point, the lamp will jump back and forth between 2-grid and 3-grid. The product adds a critical point dithering elimination algorithm to avoid this problem.
