โมดูลวัดแรงดันแบตเตอรี่ด้วยระดับไฟ LED 4 ระดับ สีฟ้า

วิธีใช้งาน สามารถต่อ Vcc กับแหล่งจ่ายแรงดันที่สอดคล้องกับสินค้า และ Gnd เข้ากับบอร์ดก็สามารถวัดแรงดันได้
โดยระดับแรงดันต่างๆที่ทำให้ LEDติดได้ คิดคำนวณดังนี้

น้อยกว่า 3.3v ต่อเซล ไม่แสดง LED
มากกว่า 3.3v ต่อเซล แสดง 1 แถบ
มากกว่า 3.5v ต่อเซล แสดง 2 แถบ
มากกว่า 3.7v ต่อเซล แสดง 3 แถบ
มากกว่า 3.9v ต่อเซล แสดง 4 แถบ


These modules provide 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.

This battery capacity display module is perfect for DIY power supplies, battery chargers, RC and electric vehicles, to provide quick and easy-to-read voltage status of the battery.

Simply connect the module to the positive and negative connections of your battery or battery pack, and the charge status of the battery is displayed in real time using a visual bar display.

The display outline color is red, and the display bars are blue.

Indicator Display Range:

1S Module: 3.3V - 4.2V
2S Module: 6.6V - 8.4V
3S Module: 11.1V - 12.6V
4S Module: 13.2V - 16.8V


Battery status display (also see illustration below):

  1. When the battery voltage is over N * 3.3V, it will illuminate 1 bar (N represents the number of battery cells, e.g. 1, 2, 3 or 4).
  2. When the battery voltage is over N * 3.5V, it will illuminate 2 bars.
  3. When the battery voltage is over N * 3.7V, it will illuminate 3 bars.
  4. When the battery voltage is over N * 3.9V, it will illuminate 4 bars. 
  5. When the battery voltage is less than N * 3.3V, none of the bars will illuminate, indicating that the battery is less than 3.3V and in need of recharging.

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
