Explanation of Lipo battery configurations

The "nominal" voltage is the average voltage across the entire useage cycle. If you charge a pack to 4.10V per cell (in series), then a 6S pack would be 6 X 4.10 = 24.6V. If you set the Low Voltage Cutoff (LVC) at 3.3V, then the battery will cut out after running the E-bike for a while, and the 6S voltage is down to 6 X 3.30V = 19.3V
