I am running a 12s4p 18650 pack. I am charging with a voltage protector and I don’t let it charge past 49.9 volts.
When I start charging the battery meter rises at a steady pace, maybe 1% every few minutes. But when the meter hits my max set voltage, and usually right around 90%, the chatging slows wayyyy down. Like 1% every 20-30 minutes.
Is this because I have the voltage protector set at 49.9v?
Should I just consider the board fully charged at 90% or should I just be waiting an extra 3-4 hours for that last 10%? I realize that’s a subjective question but I guess I wanna make sure it’s not forcing the batteries to charge beyond 90% if I shouldn’t be, if that makes sense.
