When Puma Ocean Racing decided to build a new boat for the 2011 Volvo Around the World Race, part of the decision process was the selection of the equipment used on the boat. The decision on batteries was simple: Energy1 was the first and only choice! Now, Puma Ocean Racing’s team has selected Energy1 Batteries as the official battery for the second year running. The choice is based on size, weight, power, performance and track record.
