119amps on a 5000mah pack is 23.8C, so if the cells dropped to 3.21v on that burst then yes, that is too much of a drop considering a 30C rating. But you also have to factor in losses due to wiring and the accuracy of the logger's shunt (current measuring device). Can you find out the voltage and current on the next largest current spike? That way we can verify the results.
