Discontinued
The Profoto Pro-B2 1200R Ws Power Pack with Radio Slave provides an 8-stop flash adjustment. It may be fired by your Pocket Wizard transceiver or transmitter with its built-in 32 channel radio slave receiver.
The Pro-B2 can provide 200 full power flashes per charge. Achieve action-stopping flash durations, even at maximum power output. Recycle time is 1.8 seconds @ full power, and .04 seconds @ 600 Ws.
Using the snap-on universal power adapter, the Pro-B2 can operate as a regular AC powered flash generator while the battery is being recharged. The adapter is fast, charging an empty battery in just 2.5 hours, and it accepts a wide range of input power: 12-24V or 90-240V. Included with every Pro-B2 is a standard 110/230V charger, loading the battery in 5 hours. In addition, the Pro-B2 battery is completely memory free; there is no penalty for partial charging.

Comments about Profoto Pro-B2 1200R Ws Power Pack with Radio Slave:
After using the AcuteB's for a year, I was finding I needed just a little more power under certain conditions. I still wanted to stay battery powered for portability reasons. I purchased the ProB. I year later, I still love this pack.
As the specs will tell you, it is not a light pack, but I don't mind too much. The power and speed quickly make up for it.
Outdoors, it can balance the sun quite well and provide some really nice shots. It will only start to run into power issues in the middle of a particularly bright day. Indoors it just makes for a powerful flash to run the larger modifiers out there and still keep your aperture stopped down.
Power and colour consistency are both fantastic. Power control is fine enough to not have any problems. Flash duration is great, and unless running at full power, recycle times are fantastic as well. Unlike the little AcuteB's, I haven't had any issues with auto power dumping either.
Battery life surprised me quite a bit. I was not expecting the battery to last anywhere near as long as it does. I always like to have a spare battery, but I don't find myself using it to much.
The power control will through people off a bit as there are two dials, a switch and different port configurations that need to be used to get the whole range of power settings. It makes sense, but is very odd the first time you try to use it, and it definitely could have been streamlined a little. I know a lot of people who hate this control method, so just be aware.
The only problem I have faced was more a head than a pack issue. When moving the head in a Lowepro Vertex 300 (doesn't fit the pack), the tube still managed to crack. An AcuteB head that was in the same backpack was fine. While it left a bit of sourness for a couple of weeks, I still love the pack and would recommend it highly. Hell, I have just ordered a second pack.
