Could anyone explain to me how this BMS works to see if i understand it correctly:
**broken link removed**
Ok, so when the cell reaches 4.2V or so, it will put a load on the battery, which will stop charging it IF the charging current is slow enough (42mA or slower). And that means the 4.2V battery will no longer charge, but it will continue to charge other batteries.
Ok so that is ok. But what is it in the description of this board saying there will be no balancing if we only use 25V. If cells are badly unbalanced, 1 could still reach 4.2V and others would continue to charge, only they will never all reach 4.2V cause well, not enough voltage.
I might have a problem since i will charge 6S batteries with charger for 6S that is only about 25V. Batteries dont go out of balance over the night so i was thinking. How about i normaly charge the batteries with charger. And then like two times a year i first charge batteries with 25V and then attach it directly to 25.6V with a big resistor, which would limit the current to about 20mA. And then it should work normaly balancing the cells. Would that be ok ?
