pretty sure they have stopped production on the CA and the SE styled cells. at least that's what my investigations show. the SE over 8 years ago and the CA in the last three years. I could be wrong, but I wanted bona fida brand new cells. I do not even trust the preferred forum vendors on this at this point... just too many shysters and hucksters on both sides of the pond.Calb cells with plastic shell are still available. And at 130$/kWh.
