This product adds the display switch function on the basis of the original voltage and double display, so it has the following advantages: 1. This product is powered on, click to close, press again to open, so the operation is simple. 2, the display can be turned off without long-term display, which greatly saves valuable battery power, 3, because it is not long-term display, the service life is greatly extended.
Warm sound tips: This model is not waterproof. If it is used outdoors, please waterproof it, because the electronic components should be used in a dry environment.
Recently, there has been a power indicator that automatically recognizes the number of battery cells. In fact, we also tried to develop it before, but found that there is a big problem. The simplest one is an actual 12V battery. Is it based on 3 strings of full lithium battery? 4 string of lithium batteries (4 sections * 3V = 12V) to display? This is not clear how the three strings of lithium and 12V lead acid do you distinguish? I also purchased a product from their real 3 string lithium battery to test, found that the display is very confusing, and it is very contradictory. I really don't know when to display it. After the load is connected, the display is more confusing, and the display voltage will be high and low.
Product features: 1, dual display power + voltage at a glance. The display is more intuitive. The upward 8 color bars show the battery power and the downstream voltage meter (displaying the battery voltage), and the voltmeter automatically shifts the decimal point with higher precision.
2, a wider range of use, lithium battery packs, lead-acid batteries, car batteries, electric car batteries, and other types of battery electric equipment can be used.
How to use: Connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under test. The digital tube displays the real-time battery power.
