The 12V/24V/36V/48V 8-70V LCD Acid Lead Lithium Battery Capacity Indicator Digital Voltmeter is an electronic device used to monitor the voltage and estimate the state of charge (SOC) of various types of batteries, including acid lead-acid batteries and lithium-ion batteries.

Here are some key features and functions of this battery capacity indicator:

Voltage Range: This indicator is versatile and can be used with batteries that have a voltage range from 8V to 70V. It can support 12V, 24V, 36V, and 48V battery systems commonly found in various applications.

LCD Display: It features an LCD display that shows the battery voltage and the estimated state of charge as a percentage. This display provides real-time information about the battery's status.

Compatibility: It can be used with different types of batteries, including lead-acid batteries (such as sealed, AGM, and gel batteries) and lithium-ion batteries.

Voltage Accuracy: The digital voltmeter typically provides accurate voltage readings, allowing you to monitor the battery voltage precisely.

State of Charge Estimation: The device estimates the state of charge based on the battery's voltage and discharge characteristics. This estimation provides an approximate idea of how much charge is left in the battery.

Low Voltage Warning: Some models may feature a low voltage warning function that alerts you when the battery voltage drops to a critical level. This can help prevent over-discharge, which can be harmful to batteries.

Easy Installation: It is relatively easy to install, with wiring connections to the battery terminals. Depending on the model, it may also come with a user manual for guidance.

Wide Application: This indicator is commonly used in various applications, including electric vehicles (e-bikes, electric scooters), solar power systems, UPS (Uninterruptible Power Supplies), and more.

Multiple Voltage Options: Depending on the specific model, you can select the appropriate voltage range (e.g., 12V, 24V, 36V, or 48V) that matches your battery system.

Durable and Compact Design: The indicator is typically designed to be durable and compact, making it suitable for both indoor and outdoor use.

Battery specifications:

P=lead acid, L=lithium battery, F=lithium iron phosphate battery
Single string battery nominal voltage:
Lead acid = 12V, lithium battery = 3.7V, lithium iron phosphate = 3.2V

Setup steps

  • Press and hold the setting button to power the battery, and enter the setting interface
  • Short press the setting button to select the battery specification (P=lead acid L=lithium battery F=lithium iron phosphate battery)
  • Short press the function key to select the number of battery strings (the setting key is increased, the function key is reduced)
  • After setting it, you can re-power it.

    S1: %/V 2 seconds in turn display
    S2: 10 second delay off
    S3: Turn on the backlight
    S4: Turn on LOGO
    S5: Battery curve selection


Press and hold the switch on the product, power it on, and automatically select the interface ( please follow as the code corresponds below)

Select your battery type after corresponding, for example, 3 series lithium battery, you need to enter the selection screen, press the key point to the L3 interface, then off, re-energized, and choose success, such as the need to set 12V lead-acid batteries, the key point press to P12V interface, power, re-energized, both choose success

Instruments can be used if you select them successfully. The meter shows the power interface, tap the switch, switch to the voltage interface, click the switch, and turn off the meter. the cycle shown as the code corresponds

Suitable for
L3: 3 string lithium
L4: 4 string lithium
L5: 5 string lithium
L6: 6 string lithium
L7: 7 string lithium
L8: 8 string lithium
L9: 9 string lithium
L10: 10 string lithium
L11: 11 string lithium
L12: 12 string lithium
L13: 13 string lithium
L14: 14 string lithium
P12V: 12V lead-acid
P24V: 24V lead-acid
P36V: 36V lead-acid
P48V: 48V lead-acid

Special Function Setting (requires electric iron, you must power off setting, electric iron must be grounded)
A point connection, the backlight will be automatically shut down if delay10 seconds, the voltage fluctuation will automatically wake-up exceeds 0.3V / 0.5 seconds.
B point connection, lithium choose 3-4.1V curve (lithium professionals)
