Battery Upgrade for Mitsubishi i-MiEV: Replace LEV50 battery with CATL 3.7V 93Ah battery Cells

Battery Upgrade for Mitsubishi i-MiEV: Replace LEV50 battery with CATL 3.7V 93Ah battery Cells

Is your Mitsubishi i-MiEV suffering from short range? Want to upgrade it? Good news is CATL 3.7V 93Ah lithium-ion battery cells can restore and exceed your EV's original performance.

The factory-equipped battery for the Mitsubishi i-MiEV consists of 88 LEV-50 cells. Each cell has a nominal voltage of 3.7V and a capacity of approximately 50Ah. Over time, all lithium-ion batteries degrade. When the State of Health (SOH) drops to around 80% or below, you'll notice a significant loss in range, longer charging times, and reduced vehicle performance. 

Instead of searching for expensive or scarce original LEV-50 cells, the global community of i-MiEV owners has identified a superior alternative: the CATL 3.7V 93Ah Prismatic Lithium Battery Cell.
