Romeo Power Inc (NYSE: RMO), the electric vehicle battery maker which went public recently via a special purpose acquisition company, saw its shares close 59.60% higher on Tuesday.

What Happened: The California-based company has signed a long-term contract with medium- and heavy-duty truck maker Paccar Inc (NASDAQ: PCAR) to supply battery packs, modules, and battery management systems for its upcoming electric vehicles.

According to the deal, Romeo Power will supply batteries for Paccar-owned Peterbilt 579 and 520 battery electric vehicles in the United States and Canada through 2025. The production is expected to begin after 2021.

Founded in 2016, Romeo Power has engineers from Tesla Inc (NASDAQ: TSLA) and Amazon.com Inc (NASDAQ: AMZN), among others.

The company supplies battery packs for trucks and buses, and auto parts supplier BorgWarner Inc (NYSE: BWA) is known to own 20% of the company.

Romeo makes the lithium-ion battery modules and packs them at its California facility. It claims its battery packs deliver an average of 30% greater power density than competitors which in turn ensures more capacity on wheels, longer range as well as warranty.

Romeo claims it has capabilities to address the commercial electric vehicle market from Class 3 to Class 8 trucks and it already has an order book with customers that make up 70% of the North American Class 8 commercial vehicle market.
