Battery Level Indicator Module for 1-8S 18650 Battery Pack

Battery Level Indicator provides a quick visual reference of the charge status (capacity) of 18650 Lithium-ion batteries as well as other lithium batteries with a maximum voltage of 4.2 volts per cell. Battery Capacity Tester is perfect for DIY power supplies, battery chargers, RC and electric vehicles, to provide quick and easy-to-read voltage status of the battery. 3S Lithium battery Capacity Indicator color is red and the display bars are blue. This battery capacity tester, battery level indicator module can measure the capacity or level for 1S to 8S 18650 battery pack. How Battery Level Indicator Works: When battery voltage is over N*3.3V,it will illuminate 1 block electricity quantity (note: N represents battery quantity) When battery voltage is over N*3.5V,it will illuminate 2 blocks electricity quantity When battery voltage is over N*3.7V,it will illuminate 3 blocks electricity quantity When battery voltage is over N*3.9V,it will illuminate 4 blocks electricity quantity. When battery voltage is less than N*3.3V,4 blocks display will be off; it represents battery is less than 3.3V,and you can charge the battery.
