Working voltage: 3-34V, working current: 5mA; Working temperature: -20 ℃~50 ℃
It can be used as a power capacity display for lithium lead acid nickel-hydrogen battery, as long as the required voltage is within the range of the parameter table
Display based on battery level, selecting the corresponding solder pad can detect the voltage of the battery pack corresponding to 1S-8S, which is very convenient
The battery voltage is greater than N*3.3V, and the display lights up for 1 grid (N represents the number of battery cells)
Usage: Connect the positive and negative ports of the display board to the positive and negative ports of the tested battery, and the digital display tube will display the real-time battery power
Display battery quantity parameter: (Note: N represents the number of batteries)
1. When the battery voltage exceeds N * 3.3V, it will Light up 1 screen
2. When the battery voltage exceeds N * 3.5V, it will Light up 2 screen
3. When the battery voltage exceeds N * 3.7V, it will Light up 3 screen
4. When the battery voltage exceeds N * 3.9V, it will Light up 4 screen
5. When the battery voltage is less than N * 3.3V, the four display screens will close, indicating that the battery level is 3.3V low and needs to be charged.
