I was getting the newest set ready to use and noticed they seemed heavier than the older packs.  I compared them, and found the new packs to be made up of slightly thicker cells and the wires were heavier gauge. I weighed them all, and these are the results:
>> 
>> Old Zippy 25C:   640g/pack (45.2 oz total for two packs)
>> New Zippy 25C:  690g/pack (48.7 oz total for two packs)
>> Zippy Compact 25C:  600g/pack (42.3 oz total for two packs)
>> 
>> The HK website shows the weight of the regular 25C pack as 640g, they must not have not checked the new stock.
