Battery Module Cell Detail

A close look inside one of the Leaf battery modules — the individual pouch cells are visible, stacked and compressed between the orange carrier frames. Each cell is a lithium NMC chemistry pouch; the entire 40 kWh pack contains 192 of these cells in a 96S2P configuration. Wiring them in series-parallel correctly while maintaining the OEM cell balancing is one of the most critical steps of the build.
