Hey Pal,
Ive got some ORCA cells, The are not swollen at all, The have been used for about half a season. I upgraded to some Orion 90C's. the bottom label have some wear from being on a chassis, but thats all.
They have always been kept balanced, and had a storage charge.
Ive used them every few weeks to put them through a charge/discharge cycle.
These are the ones:
