IBS supports the PNY2009 expedition. All 3 vehicles are equipped with items such as IBS IBS Dual Battery Systems, 500W Ultra Sine Inverters and IBS fitted solar technology. In the laboratory, we have tested our equipment to -40 degrees C. The IBS technique stands also to -60 degrees C with no problems, what has been proven on the journey. We wish you much success with the 2nd part of the Bering Sea-crossing.
