5V-7VDC Lithium Battery Capacity Level Indicator Module

Battery Capacity 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 indicator 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.

Features:

1. Battery type electricity quantity display.
2. Wide application fields: lithium battery.
3. Using Method: connect display board positive and negative port with tested battery positive and negative port, digital tube will display real-time battery electricity quantity.
4. Digital Color: outline red, display block blue (when battery electricity quantity is full, it will be all on)

Display Range:

5v-7v

Battery Display:

• 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.
