I use a Kill A Watt P4400 to monitor my battery charger consumption and find it extremely helpful in identifying this same situation. However, I also have an integrated amp meter on the DC side as well.
I had it hooked up to a killawatt. Near the end before the beep it was pulling 2A @ 120V roughly. So, thats roughly 4.5A going into the pack. I'll dial down the shut off voltage a bit so it slows down a bit more hopefully. I may also take the advise and try to swap cells out of the parallel pair with a weaker set to balance the pack better.
