Bill would you advocate a bottom balance with by drawing each cell individu=
ally down to 0 Volts? =

Look in the archives of the EVDL. Folks on this list have done the

experiment on other brands. A123Systems has done extensive testing as well.

The result, discharging LiFePO4 to zero volts and leaving the cell =

there for many days actually reduces the internal resistance and has =

no detrimental effect whatsoever. True fact, even though it is =

completely counter-intuitive.
