This guide provides instructions for modifying an i-MiEV battery pack, replacing the original 50Ah LEV50 cells with higher-capacity 93Ah NMC batteries.
Key Considerations: The 93Ah NMC batteries have slightly different physical dimensions and terminal configurations, requiring appropriate adaptation to ensure proper fit and connection within the existing pack structure. 1.Original 50Ah LEV50 Cell

Shanghai, June 3, 2026 – At SNEC 2026, HiTHIUM introduced what it calls the world's first native 8-hour long-duration energy storage (LDES) system: the ∞Power 6.9MWh ESS. The company also unveiled its new ∞Cell 650Ah large-capacity battery and the ∞Power 10+MWh product solution.
Xiamen, China – May 28, 2026. CATL has officially opened a major new testing facility in Xiamen. Called the Energy Storage Validation Laboratory (ESVL), the site aims to help move the global energy storage industry toward a new standard of real-world, system-level testing before projects are deployed. Covering 10 hectares and built with an investment of about 3 billion yuan (approx. $440 million USD), the company says it is the world’s largest and most comprehensive one-stop testing platform for energy storage systems. CATL intends to run it as an open facility, available for use by the wider industry worldwide.
