A123 32113 Ultra-B cell, cycling so far

[zeropointbug]

FROZEN CELL TEST

Cell temperature: -26 C (-14 F.)

Cell voltage before discharge @ -26 C: 3.456v

Discharge time: 1:56 secs (not 100% DOD, ~70% DOD)

Cell voltage with the 16ft of booster cable (6awg.): 2.02volts
Cell voltage at end of discharge: 2.86volts
Cell temp end discharge: ~10 C (50 F)

Quite a difference in start temp and end temp, at sub zero temperatures the cell is dissipating much more energy as heat... as you can see in the voltage drop.
