The Proterra Battery

In addition to reducing noise and air pollution, the design of Proterra battery packs offers an ideal application for an off-road, construction setting where safety and durability are of utmost importance. Proterra designs its batteries with safety as a core guiding principle, and all Proterra battery packs undergo rigorous testing to ensure they can withstand the toughest conditions, making them an excellent choice for Komatsu and the off-road vehicle market.

The packaging flexibility of Proterra’s battery platform further enables the optimal placement of the batteries within the middle-class excavator and replaces the need for a normal counterweight used to balance the excavator’s hydraulic arm movements.
