Top Balancing "How to"

So the BMS's 0.6 amp balancing isn't to low to depend on?

Also you say ~28Volts but 16s would be for 48V system?
Your are limited to charging under 30V with the power supply. So you have to use 8S to charge using the 30V power supply.

Yes, the 0.6A will work but you have to set overall pack voltage low enough plus limit amps as you approach higher cell voltages. That is why you move up in steps. 28V would be 3.5V per cell and balance should begin at 3.4V. Once you see any cells over 3.4V, then turn the amps down lower. This gives the passive balancer time.
 
What is the easiest way to bleed off one cell? Only resistor I have is a 10w 250 golf cart pre charge…lol…
