Giving a look at the marenius webpage I noticed this http://www.marenius.se/products/ba48uP.htm
Nice find!
I get the impression Marenius is the OEM manufacturer, because it also goes under another Swedish brand - Pearl:
http://www.pearl.se/accessoarer/index_eng.aspLooks identical, except for the logotype on the short end.
The Pearl variety retails for $440 in the US, which is a way overpriced IMHO, unless the performance is stellar.
I can't make out how much Marenius charges, because the price list got the lines mixed up:

Looking at the weight, PS2 is still lighter at 8oz compared to Marenius 12oz. I wonder how much the external Neutrik's contribute to that? Modding the outgoing XLRs for a 3,5mm plug would shed some load...
Dimension wise, the BA48uP is 120x55x35 mm, while PS2 is 102x76x32mm.
What appeals to me is the generous span for external powering, 8-24VDC.
Maybe Marenius himself can chime in on the current draw and battery life?
