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.

I had to buy a replacement for my previous unit, it failed - sudden death after 5 years, low usage. My regret with the BI unit is that it operates only with the battery, cannot plug the power supply which would be great in studio.Now I am trapped - I have the B1 with many accessories, beaucoup $$$ invested and without the battery, it has no value.Profoto products are high quality and pretty impressive overall. They should offer the battery at a much lower price to keep us going.
The ease of Profoto units is great but regret buying due to the money I've poured money into replacement batteries that die way too soon for a battery costing over $380. I have spent over $2660 on batteries. the unit is great but batteries are terrible.
battery arrived with some kind of tape over the contact points. The tape goo was so much over the connector points that the battery didn't work until a thorough cleaning was done. unclear if the tape is the fault of the manufacturer or shipper, but frustrating to have to work for a new product. fully functional now.
They will not work at any temperature close to freezing. Despite the technical specs claiming otherwise.They will not get close to 350 full power strobes after a year of consistent use. They won't even get 150.It's an awful, awful battery and I wish someone would come out with a private label alternative for the same price that actually works.Do not purchase a B1 system if you live north of Raleigh...
I have a number of Profoto B1 and B1X heads and was happy when this higher capacity battery was announced together with the B1X head, while being fully compatible with the older B1 heads. The battery also has an LED bar indicating its charge, which is very handy when the battery is not on the strobe and you want to quickly check battery charge status.
I spent about $2500 on the Profoto light and the the inside of the battery expanded and cracked. When I sent it to Profoto they would not replace the battery saying it had been dropped (which it had not). It is a shame one of the most expensive lighting systems does not back up their products
These batteries hold a charge well and have a lot of capacity, although I haven't had them long enough to see how long of a life they have. They mount easily on the B-1X and are easy to handle and charge, but they are heavy. Two additional batteries fit easily into Profoto's Two-Light Travel Kit.
