Go back to your original response to my comment. You linked to a video. And I said that the higher the balance rate a charger has the better it is for older and/or larger batteries.
I haven't tried to say anything more.
We're talking about two different things. I know that a charger with a higher current balance charge rate will charge a battery faster. I'm saying that the higher the IR the more balance current will be needed. And as batteries get older the more the IR they have.
That's what I originally asked "I wouldn't think a max of .4amps was significant."
But isn't IR what makes a cell charge or discharge faster than another one? If each cell charged the same there wouldn't be a need for a balance current. I'm trying to think at what you say controls the balance...
The IR does get worse with age of a battery. "My take is" a new battery with really low IR doesn't need much for a balance current, right?
I guess I didn't think the $10 difference in price with the minimal difference in specs from what I see was a "Ha-Ha" moment. 🤷
I'm not knocking on any...
