Features:
low-voltage warning function. When the battery is at the last bar of power left, the 12.5% ??light will flash! It is best to stop using it and charge it!

This product adds a display on/off function to the existing dual voltage and power display, offering the following advantages:
1. It is powered on and can be turned off and on again, making operation simple.
2. The display can be turned off when not needed, significantly saving valuable battery power.
3. Since the display is not permanently displayed, the battery life is significantly extended.

[Warm Tips]: This product is not waterproof. If used outdoors, please make sure it is waterproof because the electronic components need to be used in a dry environment.

There are battery level indicators in the market that automatically identify the number of cells have appeared . it had significant issues. For example, does a 12V battery display as three fully charged lithium-ion batteries or four empty (4 cells * 3V = 12V)? If you can't even tell the difference between three lithium-ion batteries and a 12V lead-acid battery, how can you tell the difference? their product has been tested  with a real three-cell lithium-ion battery. The display was confusing and inconsistent. it could not tell which display bar to show. Connecting a load made the display even more confusing, with the voltage showing highs and lows.

?Product Features?
1. Dual display of battery power + voltage is clear at a glance. The display is more intuitive. The upper 8-grid color bar shows the battery power

Downstream voltmeter (displays battery voltage), voltmeter decimal point automatically shifts for higher accuracy.

2. It has a wider range of uses and can be used in lithium battery packs, lead-acid batteries, car batteries, electric vehicle batteries, and other electric equipment.

?Product parameters?

1.   08 levels of power resolution: 10% 25% 40% 50% 60% 75% 90% 100%

2.   The accuracy of the voltmeter is about 3%.

3.   Operating temperature: -10~+65°C

4.   Working humidity: 10~80% (no condensation)

5.   Opening size: 45×26×18MM

[Friendly Reminder] Some customers reported that the meter didn't respond after wiring. This turned out to be due to unfamiliarity with electric vehicle circuitry, leading them to assume that connecting to the charging port or the handlebars would suffice. (For safety, charging ports are often isolated from the battery via a MOSFET or diode. The handlebar switch on an electric vehicle controls the motor via a controller, so it's not connected to the battery terminals.) Electric vehicle circuitry is complex. Those unfamiliar with electronic circuitry should definitely connect directly to the battery terminals or consult a professional for wiring. Otherwise, the display may not work or be damaged, at best. Worse still, it could compromise driving safety. Remember!!!
