An E-Bike battery can be of different voltages, the most common being 24 and 36 V (Volts). However, they can also be 28.8 or 48 V. It is essential that the voltage of your new battery is identical to that of your original battery.
Where can you find this information? As with technology, you can find this information on your charger or on your battery.
The inscription 24 or 29.4V indicates that the voltage of your battery is 24 Volts.
28.8 or 33.6V indicates that your battery's voltage is 28.8 Volts.
36 or 42V indicates that your battery voltage is 36 Volts.
48 or 54.6V indicates that your battery's voltage is 48 Volts.
Why does my charger say 29.4V for a 24-volt battery or 42V for a 36-volt battery? The voltage indicated on battery chargers corresponds to the voltage the battery should deliver when fully charged. It is therefore necessary for your charger to give your battery enough voltage to achieve this.
