Charging lithium-ion question. I know I need to charge away from my house.
A certain scenario keeps nagging me. With respect to CC then CV charging, is it possible to do it manually if one has a PS that has adjustable voltage and current settings? I'm not saying I would do this, but if someone had no charger however did have an adjustable PS, would the following work? This scenario is just an example to explain what I mean.
Pack is: 12v, 20Ah, 3s
To charge with an adjustable PS, can AMPs be set to a constant 3 AMPs then set the voltage to 12v and let it charge to 12v
then bump up the voltage to 12.2 leave current at 3A and let it charge to 12.2 and
then bump up the voltage to 12.4 leave current at 3A and let it charge to 12.4 and
then bump up the voltage to 12.6 lower current to 1A and let it charge to 12.6.
Would that work? That's CC then CV.
The reason I ask if this is possible with a PS is because I see guys on YT feeding 12.6 volts into a lithium battery without any mention of CC then CV.
I realize batteries have different specs so in the above scenario, let's say the individual batteries in the pack can handle a 6A continuous charge.
