Hi everyone,
Been lurking for a little while now, and learning some of the basics!
Was hoping someone would be kind enough to help me answer a few questions and check over my project. decided i'm going to try and make a 100w led flashlight.
1st question was, do I need a LED driver if i'm using an constant current boost? like the one below.

2nd question, is a battery such as this suitable http://www.ebay.co.uk/itm/NP7-12-12...rElectronics_Batteries_SM&hash=item19e749eaab
weight isn't an issue. or would I be better with 4 x 18650
3rd question, can i attach a 12V 0.6A fan to the battery above with out controlling the amperage to the fan?
Last question if i wanted to control the led's brightness how would you recommend to do this.
