This is what I got from Greg's post: Newer cell designs will be able to handle higher loads, further reducing the number of packs you need in parallel on larger planes, PLUS Kokam will be marketing pre-built parallel packs, so you won't need to know or care about how many packs are in parallel inside that big red chunk of shrink wrap
Obsolete? No offense to FMA/Kokam, but no, this new technology won't make your existing technology obsolete, if anything than for financial reasons. LiPolys are still a signifigant investment, and you're not likely to throw away hundreds/thousands of dollars' worth of LiPoly to spend even more on the newer stuff. What it will do is drive the cost of the last-generation technology down, making it more obtainable. My attitude about it is, if the old stuff is doing the job for ya, it ain't obsolete...
Back to the 3S1P vs. 3S thing: Yes, a "3S1P" pack is really just a "3S" pack, but as I said earlier in the thread, if you're consistent in how you refer to the packs, you're less likely to get confused or cause confusion. 3S1P, and you're 100% absolutely positively without-a-doubt sure that you're talking about a single pack.
