Maxamps no longer has the 50mm cells and doesn't plan to get any more... the 45mm are still current.

Yes, and the new batch of his 45's are more powerful. maxxamps doesn't overrate the cells, at least not with the 'old' 45 mm cells, i got a set of the new ones too, i will test them soon.

Cool... we can deal with new and improved...

I'll let you know how they perform. I am curious if they are different to the old types.
