    Hi, I am building a platform that will need to power 12 13watt gx23 based tube light bulbs with a battery. Could someone help me figure out what would I need to power them with a motorcycle 12v 10A battery? Will I need any special converters ? Thanks!

    I need some help with a very simple task. I'd like a quick and simple explanation please. No links if possible. My uncle and I are trying to take two 9v batteries and go from 18v to 12v. I need to know how to properly connect the batteries to each other and how I can take the voltage down.
