About How to measure the total voltage in the battery cabinet
Using a digital multimeter, you measure voltage by connecting the red probe to the battery’s positive terminal and the black probe to the negative terminal, then reading the voltage displayed. Safe handling, correct multimeter settings, and understanding voltage readings are key to reliable results.

6 FAQs about [How to measure the total voltage in the battery cabinet]
How do you measure battery voltage?
Solution: Measure the internal resistance. How you can do that? Apply an additional known current and measure the difference in voltage. With that you get the internal resistance and with the measured current from above, you get the real battery voltage.
How do you test a battery with a multimeter?
Connect multimeter probes to battery & measure the voltage. The voltage should fall across the specified in the cell or battery’s datasheet. For NMC (Nickel-Manganese-Cobalt), this will range between 2.5 V & 4.2 V per cell. An LFP (Lithium Iron Phosphate) cell (or) battery will have a voltage between 2.5 V and 3.7 V.
How to measure a battery with a reference voltage?
You can measure voltage battery with voltage reference. You need voltage reference with lower reference than you expect on battery (for example 1.235 V). Then you measure this voltage with your ADC. With this measurement you can now calculate ADC reference voltage, which should be equal to battery voltage.
How to measure battery voltage Vb?
For example if you measure 300 with your ADC and your reference voltage Vr is 1.235 V then your battery voltage Vb is 4.2 V. Another similar, but more complex way is to use voltage divider on battery and use internal voltage of arduino for ADC reference.
What tools do you need to test a battery?
Without the correct tools, you won’t be able to accurately test the voltage in your batteries, which could lead to inaccurate results or even potential safety risks. Here’s a quick list of the tools you’ll need: Multimeter: This is the primary tool for testing battery voltage. It’s versatile, accurate, and can measure both AC and DC voltages.
Should a battery be loaded at the time of measurement?
To measure the battery properly you indeed should not be loading it at the time of measurement. If you know that your Arduino will be in a low power/standby more at certain times, it will then be consuming only a very small current that should not load the battery so much that the voltage drop is significant.
