Diy regulated box question

[nickthefogmachine]

hi everyone, i have an old smok xpro m65 and i want to make a triple parallel box mod with the m65 board, my question is about onboard charging that thing. it has the ability to charge at 2 amps , so if i use it to charge the 3 battery modification will it charge each battery at 660 mA??? and when the charging will stop? as soon as one battery reach 4.2 volt?? or because its parallel the batteries will equal their voltage evenly at any time???. is there a chance that it will have different battery voltages and it will take the middle voltage and overcharge one battery?
example with two batteries would be one be at 4 volts second at 3 and the mod reads 3.5 volt so it will continue charging them till battery one gets damaged

If the batteries are in parallel, they'll all have the same voltage. Charging current will be split amongst them until all are charged.
