I know very well how many topics have already been created here. Will it be wrong if I add another one? I don't want to litter your discussions by contributing to other threads. I wanted to ask about some differences that arise when measuring current voltage. My bms on a 12V 50Ah battery, indicates a value of 13.65V as the final charging voltage, actually 99%. While the meters indicate much higher, like 13.9V and 14.1V Leaving aside the accuracy of the instruments and the voltage drop on the wires and connections, I was sure that the voltage on a single cell, can reach a value of 3.5V at almost full charge, and here it comes out 3.41V One of my meters is a Chinese DC meter and I generally trust it, because it indicates accurate voltages for reference. Having 14.1V on it, the BMS indicates 13.65V I don't really get much by it. I apologize if what I wrote is not entirely understandable, but I'm still propping up the translator.
