Hi David and All,     You are correct  likely for a new balanced battery set started at exactly the same charge.  But after a while the differences will get larger and I'll likely be using used Leaf cells made into 100-200amphr packs which may work with only 100ma load on the highes

 Hi Cor and All,     Thanks for the info.  Sounds good for an E bike 24vdc nom pack but too little balancing for a 100-200 amphr ones I want. I'm looking at either Leaf or Volt cells/batteries because they seem the low cost way and a low parts count BMS to keep them alive fo

Jerry, The datasheet says it is a monitor/balancer. Balance current is 100mA and what I understand from the description is that a single external resistor is multiplexed between the high cells, so worst case if you have 1 low cell and 6 high cells, each high cell effectively is connected to the re
