Correct, but the difference between conventional lead acid and lithium though is that with LA, when one battery becomes fully charged the charger keeps going and overcharged it whilst the other two or three batteries catch up. They are essentially top balanced at every full charge as they can tolerate limited overcharging without too many problems.
Lithium, on the other hand absolutely cannot be overcharged and when the BMS of the most charged battery decides it's time to intervene and stop charging, so do the other two or three, as they are connected in series, even if they are no where near full.
