What do you mean by drawing the pack down?  I can see that if you
discharge a 120V pack to 60V there is a problem, but momentary high
current loads that draw the pack down should not be a problem, right?
me

The resting pack voltage will be say 125 volts but when I draw say 380
battery amps the voltage can drop as low as 65-75 volts. 
This problem seems to be much worse when the ambient air temp has been in
the 20's or 30's all night.

As of December, when I was there doing Xmas shopping.

Deka is kind of a premium brand; The Sam's Club ones are probably Exide 
(though it seems to depend on who was the low bidder).
