Had a big job come up and needed to add to my Profotos that I already own.Everything was in great condition and worked perfectly.The whole process was great.

I purchased this battery as a replacement for the original one which came with the light u purchased here on B&H.That one i used around 20 or something sessions, during a 5 year period. And then it died.From my perspective, the lifetime of the battery isn't worth the price.I'll count how many days this one lasts. I'll report back when it dies.

These are cripplingly expensive. The technology inside is found in other batteries at a fifth of the price. It's hard to justify sticking with Profoto considering the need to replace these on all four of my B1's every few years. I find the recycling time on my older B1 batteries slow making it hard to shoot with them in real world shoot scenarios where you need to shoot fast with consistency.
