The H2-23 features the company’s highest-density battery—176 Wh/kg and 270 Wh/L—which supports systems up to 2 MWh.
“The new H2-23 battery pack represents more than just a technological advancement — it embodies our renewed focus on powering the shift to a sustainable future,” said Claire McConnell, Chief Business Officer at Proterra. “We’ve created a solution that delivers unparalleled performance even in the most challenging conditions. Every mile driven with our technology helps bring our customers closer to their zero-emission goals.”
