we could call the cell chuck norris

What changes in MRI would you expect for SOC of cells ?

Also the chemical process sounds rather less precise than an electrical balancing circuit, so it seems to me that while these cells may not die quickly from gross overvoltage, they'll still grow out of balance with each other. Worse, it may be more difficult to balance them since the chemical process will start getting in the way, necessitating more charging current for some cells, and therefore more bypassing current for others.
This balancing problem would not occur if the chemical processes started taking effect at a high enough cell voltage, say 4.0 VPC, so you can still balance as normal (e.g. while charging) at 3.65 VPC.
Surely it has to produce heat to "cap the voltage". The lead acid gassing happens at a precise voltage (though dependent on temperature I think?) and is integral with the chemical reactions that make the stored energy available as electricity. But the proposed reactions would presumably be independent of the cell's chemical to electrical conversion process. It might be just as precise, I suppose; it just seems unlikely to me.weber wrote: Er, are you reading something other than the above article? Where did you get all this about it producing heat and being imprecise and taking effect at too low a voltage?
