New and improved brushless high-power pedal generator
To charge a 12-volt battery, you need to charge with a 14-volt voltage,
To charge a 24 volt battery, 28 volts are required for charging.
This 14V generator can be directly equipped with a 12V DC motor.
This 28V generator can be directly equipped with a 24V DC motor.
12V battery=14V generator ,24V battery=28V generator
If the generator comes with a voltage stabilizer, just connect it directly to the battery
