Hello, am currently trying to construct a disposable device that requires a power supply adequet to make up to 4cm of nichrome wire glow , and use as little space as possible. however, currently i am having a small issue as the output strengths of small batteries seem to be unpredictable, and i dont know wether or not these small lithium batteries will produce enough output to get my nichrome wire glowing, for instance, i have a sub c rechargable battery for starting my nitro powerd rc car's glow plg, and it says it produces 1.2v and has a capacity of 2000ma, and it is so strong that it burns up my wire immediately, but then i use my single 1.2v 3000ma rechargeable aa battery, and it doesnt do squat, now why is that?, obviously i know the glow plug battery is meant to discharge faster and allow for more power than AA. what i want to know is, will this small 1/2AA battery be enough to make this nichrome wire glow, which i might add that can be made to glow red hot with a ni-cad 4.8 700mah battery pack. and burn out with a 9v battery. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item;=310101398351&ssPageName;=ADME:X:RTQ:US:1123 this is the battery i am looking to see to use in my device, as it is small enough, and appears to have enough amperage and voltage to be able to burn the wire, but still, as i tested out with my other battery, i cant really tell without actually having it, and i dont plan on waiting 3 weeks to test out the battery. http://cgi.ebay.com.au/NEW-3-6V-1200mah-1-2AA-ER14250-14250-Lithium-Battery-/200535000934?pt=US_Batteries&hash;=item2eb0d14766 otherwise, if this alone cannot burn my nichrome wire, are there any batteries out there that are cheap (especially in bulk), are not much larger than this battery, and have a fast discharge rate, or, if there are any very small basic circuits i can use with this battery, to increase its output to enough to burn the nichrome wire, as i dont ant to exeed the size of a large cork, or roughly or (3x2x2) +/- 1cm3 lastly if i buy a smaller diameter wire, such as this one will a AA battery be enough to burn it? or the 1/2AA http://cgi.ebay.com.au/Resistance-heating-wire-Nichrome-40-awg-100ft-/170454797490?pt=LH_DefaultDomain_0&hash;=item27afe5ccb2 does the amount of ohms per meter mean it will get hotter with lesser power i have considerd using very low voltage incendary light bulbs, however due to the fact i want to make alot of these devices whiches name i will disclose, i find that they may cost me alot more, than what i could get for nichrome rocket wire. whoever answers this first , will get a "best answer" from me.
