Eric,
I just got back from doing some quick measurements. Excuse me that the resistance that I am looking at for my nichrome coil is .1-.4 ohms, yes it is very small. I have a stack of AA Duracell Copper Top batteries in series putting down 6v and 9amps. Each Copper top has the ability of 2+amps.
I need a circuit that will allow the nichrome to heat up to 800 degree (I did the math for this gauge and amps) and have a following circuit/chip to down the volts/amps back to the battery so it doesn't heat them up. Basically too much current/voltage back to the batteries. I am researching transformers, inverting amp, capacitors and inductors for my solution. I can't do much resistance because the low impedance of the nichrome.
