I store mine the same way but out of all the brands I have the SMC packs are the only ones that I seen that the manufacture says not to store with a full charge. Not sure why their cells are different but I'm sure they tested this stuff out and come up with this for a reason.
Like FossiRC though I stored my packs fully charged and some where SMC and so far no problems. I do keep my packs in a lipo sack. Maybe I will store them with about 10 to 20% less charge when I put them away. I will have to do more reading from different companies and see what they suggest.
Most of my new packs come roughly charged to 7.9volts to 8.2volts when I get them new. Not sure if they charged them to this voltage or they lost some voltage while sitting until they are sold.
