Upon power-on, the device first detects the number of battery cells, defaulting to mode 0. The display illuminates after approximately 1 second and shows the current battery percentage. At this point, short pressing (within 3 seconds) the intelligent button switches on\/off the device, while long pressing (over 3 seconds) switches between modes, allowing you to switch to mode 1. After switching to mode 1, the display turns off by default. Short pressing (within 3 seconds) the intelligent button immediately turns on the display, and the value increases from 0% to the normal battery level within approximately 1 second (due to the reuse of button functions, the filter capacitor needs to be charged after being turned on). Then, it automatically turns off after a delay of 3 seconds. Long pressing (\u0026gt;3 seconds) the intelligent button switches back to mode 0, and the cycle continues;\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eKBAB0066-003 (4.2V in parallel)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eProduct Parameters\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eProduct parameters: Maximum voltage resistance: 36V±10\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eVoltage range: 3~4.41V\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eBattery capacity: Unlimited\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eBattery level display: 0% to 100%\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eDetection accuracy: ±0.25%\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eAverage operating current: 7mA±0.3mA\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eRefresh frequency: 0.3 seconds\/time\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eOutput control: None\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eReverse polarity protection: None (Do not reverse the positive and negative poles, otherwise the module will be damaged)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px; font-family: Verdana;\"\u003eApplicable battery range: The module is suitable for all single lithium-ion batteries or multiple lithium-ion battery packs in parallel with a rated voltage of 3.7V (full charge voltage of 4.2V), such as 14500, 18650, 21700, polymer lithium-ion batteries, and batteries of any capacity and size.
