    Why does my charger have different voltage than the battery

    THE BATTERY IS 48 VOLTS AND THE CHARGER IS RATED FOR 54.6 VOLTS. WHY?

    When we say a battery has a certain voltage such as 48V this is what is referred to as the nominal voltage, or in other words the voltage that the battery would be when it is at about half of its charge. As the battery is charged higher than that the voltage is higher than that, and when the battery has less charge left in it the voltage is lower.

    A 48V battery will top out around 53V give or take, and the charger must have a higher voltage than the highest possible amount of voltage that the battery can reach.

    It's like if you were trying to air up a balloon, you would have to blow air into the balloon at a higher pressure than what is inside of the balloon.
