Equivalent Lipo replacement for 60v 15Ah Ping

[Speedfreke]

According to dogman , Isn't 20s lipo actually 4.2 x 20 = 84v? That is probably too high for my 20amp 72v controller.
I think 18s is what I need if there is such an animal.
Does anybody know if larger lipo cells are available both in voltage and amperage? I personally don't like using tons of batteries.
Does lipo come in pouches which would make the pack more compact?
I know I can research this but I would love to hear from people who have had direct experience with different types and combinations.

20s lipo is 84V fully charged, but it's 74V nominal, as I just posted in my last post. You can use 18s if you want. It's actually a 66.6V nominal pack that will fully charge to 75.6V. if you have a 72V controller, either will work unless it's really not a 72V controller and only labeled as such.
