Nyobolt hits $1B valuation with $60M Series C for fast-charging batteries
What's the deal? Nyobolt, a Cambridge-based maker of ultra-fast charging battery technology, has closed a $60M Series C round at a $1B valuation. The round was led by Symbotic (NASDAQ: SYM), an AI-enabled robotics firm, with participation from IQ CapitalDealroom has a profile for this one.

The company says its revenue grew five times year-on-year, driven by demand from physical AI applications and AI data centre infrastructure.
Why now? Autonomous machines are moving from factory floors to warehouses, hospitals, and city streets — and their energy demands are outpacing conventional battery technology. Inside data centres, GPU racks running large-scale AI workloads generate intense power spikes that legacy backup systems weren't built to handle.
Nyobolt's technology is already deployed at scale. For Symbotic's SymBot autonomous mobile robots, its batteries deliver six times more energy capacity than the ultracapacitors previously used, weigh 40% less, and achieve at least ten times the cycle life of traditional lithium-ion technology.
"The enterprises deploying autonomous systems at scale can't afford downtime, swap time, or power flickers," said co-founder and chief executive officer Sai Shivareddy.
What could go wrong? Battery technology is a crowded and capital-intensive space. Nyobolt must scale manufacturing while competing against well-funded incumbents and other startups chasing similar markets. The jump from warehouse robots to broader applications — hospitals, city streets, data centres — adds complexity and regulatory hurdles.
A $1B valuation on $60M in new funding also implies high expectations. If physical AI adoption slows or customers consolidate around different power solutions, justifying that price tag could prove difficult.
The signal: Symbotic's dual role as lead investor and customer underscores a pattern gaining traction in deep tech: strategic corporates backing the infrastructure they depend on to scale. With revenue growing five times year-on-year, Nyobolt's trajectory suggests that ultra-fast charging is shifting from a niche capability to a core requirement as autonomous systems and AI data centres push conventional battery technology past its limits.
