Charging and discharging of lithium ion battery
CV (Constant Voltage Charging) The constant voltage (CV) threshold for lithium batteries is typically 4.1v to 4.5v per cell.

Once the battery reaches the constant voltage charging threshold, the charger IC transitions from constant-current to constant-voltage regulation.
High-voltage EV battery packs: benefits and challenges. More voltage
As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross
