Volta Power Systems Releases New Flagship Power System, FLEX


Volta Power Systems announced FLEX, its newest line of engineered li-ion energy solutions for RV, work truck, and specialty vehicles. The FLEX energy storage pack features a redesigned case, heating pads, and a proprietary battery management system (BMS). Volta drew on user and OE feedback to adapt and add features for improved cold-weather performance and more flexible controls. The feedback also helped improve additional data capabilities and error-proof connectors for faster installation.

FLEX represents Volta’s complete system including generation as well as storage, and distribution. As with previous Volta systems, FLEX scales in increments of 3.3 kWh modules with multiple pack sizes. These packs work independently or together to meet the needs of virtually any mobile application. Likewise, the system pairs with Volta-manufactured alternators for under-the-hood generation on most US truck chassis from 6 kW to 11kW to rapidly charge while driving. Further, an array of DC converters and AC inverter options can provide 110V, 220V, or 208V 3-phase distribution.

“Customer feedback is the heartbeat of innovation at Volta, and the diversity of industries we serve creates a great opportunity to learn and cross-apply feedback to make our products even stronger,” says Jack Johnson, co-founder and CTO. “Process-based innovation is a lesson hard-learned in our team’s deep automotive industry experience, and FLEX is a great example of listening, predicting, and exceeding the needs of customers.”


Volta’s FLEX allows users to take advantage of the latest BMS. This enables an end-to-end software and hardware system fully supported by Volta’s expert team. The BMS provides enhanced monitoring and control while integrating heating solutions that use internal energy to heat the system faster. As a result, cold-weather performance improves, along with adaptable IO capability to flex to diverse customers’ needs.

“For the FLEX, we worked hard to continue improving safety, performance, and reliability that our customers count on,” Johnson says. “We’re grateful to customers for their continued honest feedback and collaborative improvement of our power systems that have allowed us to sustainability grow into the company we are.”

Finally, Volta roughly doubled its sales in 2021, expanding its manufacturing space to twice its footprint. The company projects revenue will double again in 2022.
