Re: (ET) Running Hawkers as a aux pack for an E-20

Have you actually measured each module's true capacity (discharge test)?  
It 
sounds like their capacity varies quite a bit.  The one with high voltage 
probably has the least capacity, so it was fuller than the others.  It 
might 
also have more internal resistance.

Resting voltage doesn't tell you much about capacity.  A sulfated battery 
might read low, but there are many other depreciation mechanisms.  Such a 
battery might really be fully charged, but can deliver only 10 or so amp 
hours 
instead of 26.  Thus the only time the pack is ever balanced is at full 
charge 
(if then).
