It’s a nice chip specifically designed for 4 cell BMS usage.I’ve now settled on a ATmega406 based design

I do like this approach.The philosophy of this design is in my case with 3x 4S packs , I have in effect three completely redundant battery systems each with it own BMS and local safety disconnect contactor. Even though the three can act in cohort , each one can also function without the others.
Yes I think it offers the best chance of redundancy.I do like this approach.
Is it really that much heat?.75 mill ohm you have Watts of heat to conduct away
At full 200A it is 200 x 200 x.00075 = 30 watts heat dissipationIs it really that much heat?
Maybe 4-packs on a board would be easier to work with.I think the cell level bms is a very interesting I could seperate out the active balancer as this is a seperate module per battery
There is a ATTINY cell based open bms project already
