I use the 155B as well and I find the biggest thing to factor is voltage loss. We do 27.3 volts to charge and by the time it gets up to the Powerbox up top, it's down a volt or two. Then the voltage to the equipment tends to be 23-25 volts.
As was said, though, 27v should work just fine directly to the equipment. Ubnt seems to be the closest and it seems to work without problems.
