About Sreekanth

I am a battery engineer with experience across automotive, grid-scale (BESS), and residential energy storage systems, with a strong focus on battery validation, performance analysis, battery analytics, lifecycle modeling, and BMS behavior. I have worked on battery testing according to relevant standards, data analysis, and system-level understanding from cell to full system integration. My experience also includes system sizing, electrical integration, and supporting real-world project execution.

With this background, I can support investors, developers, and engineering teams in evaluating battery and energy storage projects from a technical perspective. This includes assessing system design, performance expectations, degradation risks, and overall feasibility, as well as translating complex battery data into clear, actionable insights for decision-making.
