BATTERY CAPACITY INDICATOR MODULE 1S 3.3 TO 4.2 V

Overview1. When the battery voltage is over N*3.3V, it will illuminate 1 block electricity quantity (note: N represents battery quantity) 2. When the battery voltage is over N*3.5V, it will illuminate 2 blocks of electricity quantity 3. When the battery voltage is over N*3.7V, it will illuminate 3 blocks electricity quantity 4. When the battery voltage is over N*3.9V, it will illuminate 4 blocks of electricity quantity 5. 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
