How thick is the casing on LiPo cells?

[dlmcmichael]

Can anyone tell me how thick the casing of LiPo cells are and what they are made from? In particular larger Flight Power packs like the 4900 mah 6S1P EVO 25. I tend to treat them like tissue paper and worry when I think I see a new "dent". I would like to have a feel for how much abuse they can take without causing any damage so I can stay way away from that. I think my level of care is probably overkill but would like some confirmation of that. I have an Align 6S2P with 41 cycles on it and have not had any problems with it yet but would like to ease my mind a little about handling. Also just got the FP pack, double the worry !! Thanks....

Well not sure how thick or thin they are but... You could drop one, accidentally, from a foot or two without worrying too much about it. But if you have a visible -DENT- in the pack I would contact Flightpower for guidance or warranty.
