[RE-wrenches] Imbalance In Multiple String Charging Current

[Mark Frye]

Folks,

I have three strings of batteries cabled in parallel to a common buss bar.

During charging, one string takes significantly less current than the
others.

What can I infer from this? Is the low current string healthier, presenting
higher impedance due to a higher state of charge? Or is there a single bad
cell with high impedance in this string? Both, neither, something else, or
can't know without further information?
