i have got my new titan 510 now im looking to buy a true 5 volt mod i want it to always be at 5 volts i like the look of the nhalier but i dont think its 5 volts and i dont want to burn up attys with to much voltage any ideas?

Five volts will burn out attys a lot faster. You can get a TIP voltage regulator at Radio Shack for a few bucks, or a TI Plug In Power Module that you can adjust the voltage with by a resistor (fixed voltage. I have mine at 4.2V). I still burn out attys quicker at 4.2V.

what about a high voltage atty how do they work and if i wanted to buy a flash light to mod like robs 5 volter how do i know its the right one i dont own any cr2 or cr123 batts that everyone uses so i dont know how big they are im guessing that there half the size as a standard aa bat id realy like to make my own 5 volt pv but lack the know how

oh and i also dont know where to get a 510 battery socked to connect the power to

I find that using a big battery like an 18650 works just fine. It will hold up at >4V for a couple DAYS and that's plenty to produce a cloud of vapor. It will fit inside one of the Dollar store flashlights. I had one maintain >3.8V for four DAYS. Much easier and MUCH safer than ganging batteries together.
BTW, ALWAYS USE PROTECTED BATTERIES and read the information on the web sites before messing with these things. They can burn and explode!
