how do i increase the current draw from a 3v non-rechargeable lithium battery?
hi, ive got some 1/2AA batteries that ide like to use to make some nichrome wire glow, in a really small device. now, using one of these batteries, im able to make my nichrome wire glow with one , but only if there is less than 0.5cm of nichrome. if i use two batteries, and increase the voltage form 3.6v to 7.2v, then the length of wire it can make glow increases to 1.2cm, which is ok, but two batteries take up too much space.
So i want to know, is there anything i can do, to increase the voltage or current of the battery? such as a simple battery drainer or something that would pull its power rapidly and pass it all through the nichrome wire so that it would glow the same as if the voltage was doubled without actually using a second battery?
