• Operating temperature: -10°C to 65°C
• Dimensions: 44 x 20 x 9.2 mm
• Backlight colour:
  • Blocks: Blue
  • Battery envelope: Red

Levels of illumination:

• • Under 9.9V: 0 blocks
  • 9.9V - 10.5V: 1 block
  • 10.5V - 11.1V: 2 blocks
  • 11.1V - 11.7V: 3 blocks
  • Above 11.7V: 4 blocks

Functional description:

The indicator is equipped with a 4-stage LED display that accurately indicates the battery charge level. Each charge level is indicated by the corresponding number of blue LED blocks:

• • Under 9.9V: No block lights up, indicating a very low level of charge.
  • 9.9V - 10.5V: 1 block lights up, indicating that the battery is 25% charged.
  • 10.5V - 11.1V: 2 blocks light up, indicating 50% charge.

• • 11.1V - 11.7V: 3 blocks are lit, indicating 75% charge.
  • Above 11.7V: All 4 blocks light up, indicating that the battery is fully charged.

In addition, a red border illuminates when the battery is discharged below 9.9V, a clear warning signal.

The compact dimensions (44 x 20 x 9.2 mm) make it easy to install the indicator in a variety of devices, while ensuring precise monitoring of the battery's state of charge over a wide temperature range from -10°C to 65°C.

This 3S Li-Ion/Li-Po battery level indicator is an indispensable tool for anyone who needs to monitor the voltage of their batteries with high accuracy and reliability.
