[Ryu James]

hey all,
so i am going to be using the castle bec to power the esc and reciever. but i have a small 2s 1350mah lipo that i want to use strictly for my 6v fans. how would i hook this up? do i just connect the batter directly to the fans? or maybe connect to a switch harness and then the fans? or do i need some type of resistor or something like with led's?
