Using a DC-DC converter to power 12 volt devices on a 24 volt vehicle is the best choice and does not adversely effect battery life. If a 12 volt device is powered from only one of the vehicle's batteries an imbalance occurs in the charging voltage across the batteries causing one to under charge and the other to over charge. Using a DC-DC converter eliminates the charging imbalance.

The model ST 340 is commonly used to power cell phones, GPS units, radio and audio equipment, lights, etc.

This model is also a popular choice for powering 12 volt electric brake controllers in military vehicles.

If your application requires more than 20 amps at 12 volts see model 362 or 364.
