YPHOS lights can be powered by any type of marine battery or DC power supply of the appropriate voltage. Drivers are integrated to the lights, and there is no need for external drivers.
Always check the input voltage rating of your YPHOS light fixture to use a battery with the appropriate voltage. All YPHOS fixtures work at a range of voltages:
e.g. 12V DC lights can work between 10-15V DC.
e.g. 12-24V DC lights can work between 9.6-36V DC.
