About

Volt Harbor builds modular, software-defined battery energy storage systems for data centers, utilities and commercial and industrial sites. Its MAC-BESS platform borrows a Medium Access Control architecture from computer networking so battery modules of different chemistries, manufacturers and ages coordinate power flow with each other in real time. The company was founded in 2024 in Ann Arbor, Michigan around six patents licensed from the University of Michigan, and emerged from stealth in May 2026 with a $2 million seed round led by MFV Partners.

A networking-style Medium Access Control layer lets mismatched battery modules, including second-life EV cells, share one system and be reconfigured by firmware rather than by hardware changes, delivering sub-100-microsecond response and up to 30% longer battery life.
