I also see the cell voltages but the BMS board isn't flashing or seem to be balancing.
Anyone have any input on what I'm missing? Is there a specific setting? The BMS status keeps saying "no" next to "bat balancing"
I chose "custom" I believe i put in max cell voltage as 4.10, min as 3.10, critical as 2.5, balancing as 4.10. I'm running samsung 25R cells. Should i be putting in max as 4.2, min 3.1, and critical 2.5? I wanted to increase longevity of cells so i thought charging them to 4.10 down to 3.10 was a good range. That means i set my charge voltage to 82V, high voltage cutoff to 84V with 1V softlimit. I'm not sure if that's the correct way. What have people been doing for 18650 cells?
you'll want to put balancing below max cell voltage. if max is 4.1 and balance is 4.1 it probably wont kick in.
mine is max cell voltage 4.12 balance voltage at 4.06
this way at you approach the top the balancing kicks in
