Nominal voltage chart for 48V (13S) Li-Ion Ebike batteries showing the percentage.
13 Cells x 4.2 Volts/Cell = 54.6 Volts Fully Charged
Assumptions: Your pack uses typical 18650 cells which charge to 4.2V and discharge to 3.0V.
Disclaimer: This chart is a theoretical guide only. No responsibility is taken by for damage occurring from incorrectly charging your battery. Please follow the directions in your user manual. Always charge your ebike battery in a fire proof area with a timer switch to avoid overcharging it. If your battery doesn't reach the 100% voltage listed above, DO NOT force it to go any higher than the voltage that it is charging to.
