As far as the "an apparent cell change" description goes, you should be able to contact the vendor that you ordered from and get a reliable answer to what it is you are buying, if the the vendor in question is on Mooch's list of trusted battery vendors. (liionwholesale.com is on that list so probably not all is lost.) Consistency issues between cells is a whole other matter, though... if using two cells in a dual battery regulated mod, "consistency issues between cells" implies that one cell might be heating up noticeably faster than the other cell during use and or one cell might have a capacity and or voltage sag that differ(s) noticeably from that/those of the other cell so the two cells don't discharge equally resulting in a difference in voltage between the two cells. But if you follow Mooch's temporary new rating of 20A-25A for this battery, you could still use this battery safely (i.e., sufficiently safely), and, if you have a dual 20700 capable regulated mod that you can verify to be working correctly (by using other batteries you know aren't suffering from consistency issues between cells and by using an accurate voltmeter to verify that the difference in voltage between the two cells is staying, nearing the end of the discharge cycle, pretty close to zero difference) you should be able to "test" (well sort of anyway, but not as reliably accurate as Mooch runs his tests...) for noticeable inconsistencies by measuring the voltages and by feeling if one cell gets noticeably warmer than the other when using them together as a pair in that same dual battery regulated mod. Taking this approach should at least give you a preliminary indication of the magnitude of the inconsistency between the two cells until Mooch comes up with the real test results. Despite this, I can't recommend you to use these batteries above 20A-25A right now of course, but all I'm saying is at least you could decide to try and figure out what chances you have that these batteries will still turn out to be of some (sufficiently safe) use to you. The only other option I can think of would be to simply just cancel your order.
