Eliminating BESS Data Silos: volytica & Cellect Launch Native API Integration

DRESDEN and BARCELONA — March 3, 2026: volytica diagnostics, a specialist in advanced battery analytics and diagnostics, and Cellect Energy, the BESS-first portfolio operating platform for owners and operators, announced a native API to enable seamless BESS data integration for grid-scale battery energy storage management. The partnership creates a unified environment combining OEM tools, analytics, and trading interfaces in one efficient ecosystem.

From Data Silos to Actionable BESS Data Integration

As battery storage portfolios grow in size and complexity, consolidating fragmented data sources into a coherent system becomes increasingly important for efficient asset management. This BESS data integration eliminates data silos by providing operators with a unified platform. This platform brings all relevant battery data together into one single source of truth, translating insights into clear, actionable maintenance workflows for both O&M and commercial teams.

The impact of this proactive approach is significant. Internal analysis and industry benchmarks indicate that unaddressed technical anomalies, such as cell imbalances, can put more than 10% of annual revenue at risk through capacity “stranding” and accelerated degradation. By centralizing these insights via API, the integration significantly reduces administrative overhead. Teams save critical time by eliminating the need to cross-reference multiple logins and disparate dashboards. This enables faster, data-driven decisions that safeguard asset health.

For volytica, this BESS data integration represents an important step in embedding diagnostics directly into day-to-day asset management. “A BESS is only as effective as the environment it is embedded in,” says Claudius Jehle, Founder and CEO of volytica diagnostics. “By integrating our diagnostics into Cellect’s platform, we are placing a critical piece into the operational puzzle. Our goal is to equip asset managers with our vdx sentry, a virtual battery expert that turns battery data into clear, actionable workflows. This enables teams to focus on maximizing asset performance, revenue stacking, and value retention rather than jumping between isolated dashboards.”

For Cellect Energy, the collaboration strengthens its vision of a unified environment where operational, commercial, and diagnostic insights converge. “Cellect is the portfolio operating layer for grid-scale storage — the place where commercial intent, operational reality, and performance evidence come together. With volytica diagnostics now natively integrated, advanced battery analytics are available in-context inside Cellect. This helps teams move from diagnostics to decisions faster. It also enables new capabilities built on the combination of battery intelligence with operational and commercial signals,” adds Leon Gosh, Founder and Managing Director of Cellect Energy.

A Shared Commitment to an Open Industry Ecosystem

Both companies remain dedicated to an open, manufacturer-independent approach. While this native integration offers a seamless experience for shared users, both remain committed to a collaborative ecosystem. volytica delivers its specialized expertise through flexible APIs for various platform and trading providers worldwide. Meanwhile, Cellect continues to expand its network of partners to ensure operators maintain full freedom of choice.
