How to visually measure the voltage of a lithium battery pack
lithium ion
Now let''s say that we measure two voltages: Vcell -> this is the voltage measured at battery connection when PWM is OFF; Vchg -> this is the voltage measured at battery connection when PWM is ON; To be clear I''ve checked the source code implementation of both. During CC charge phase the algorithm periodically checks if the Vcell > Vmax=4.2V.
