Zippy FM lipos not fiting Erevo compartments

[NoControl]

Got some zippy FlightMax 3s 5K 20c lipos fri. Hobbyity says the lipos dimensions are "Dimensions: 144x50x25mm" and the measurements for the erevo battery compartments are 150x51x30 (if you don't remove the 10mm foam at the one end of the compartment). Th actual measurements for the pack are 142.61x51x24.15. If you do the math that should leave 7mm length and 5.5mm or so for the heigth. However I can't seem to get the compartment door to close all the way, the front latch will latch, but where the connector has to come out won't even close all the way, anybody have any suggestionsshort of getting different lipos, or dremeling out that area of the door?
