So who's starting to get bored with my graphs

Here's the result of the pair of Zippy-H 5000 mah 3S 20C constant I have. They are my oldest packs but they are not the ones with the most cycles. Around 20 cycles, I didn't really keep track for those lipos as I use them more for the fun factor they give.
