    Great stuff

    Bought those cells for my Profoto Acute batteries. They use _exactly_ the same cells. Now the batteries work like new.

    These cells simply work

    I've purchased some 200 A123 cells over the years. My West Mountain CBA battery analyzer shows these cells are near identical in performance. And they last many years with little change in performance under 40 Amp loads.
