Please note:
1. The 1 string, 2 strings, etc. mentioned in the figure refer to the nominal 3.6/3.7V battery pack; 4 series of ferroelectric batteries are common to 12V acidic batteries, 8 series of ferroelectric batteries are common to 24V acidic batteries, and so on.
2. The minimum display voltage of the universal model within 30V is 5.8V, and the maximum peak withstand voltage is 30V. Please be careful not to use it for batteries above 24V! Because the load is prone to generating high surge voltage, it is easy to out the display.
3: The minimum display voltage of the universal model within 100V is 7V, and the maximum peak withstand voltage is 200V.

Usage:
Connect the positive and negative terminals of the display board to the positive and negative terminals of the d battery, and the dial tube will display the real-time battery level.
It has an undervoltage warning function, and the 12.5% light fes when the battery is only the last cell full. It is best to stop using and charge at this time.
Wiring method: red positive, blanegative
