mavrick5x5 Posted April 29, 2007 Report Share Posted April 29, 2007 Hi all I have in mind a new project and i need to get some advise, has any one figured a way of running there weapons using 12 volt batteries? ie a car battery i have tried to find a voltage adaptor but it only give 1.5 amps which isn't enough to power the weapon. can anyone help? cheers ivan Link to post Share on other sites

It is big and heavy and not worth lugging around for a day. Link to post Share on other sites
happyboy Posted April 30, 2007 Report Share Posted April 30, 2007 You can buy a 12v airsoft battery. Link to post Share on other sites

mavrick5x5 Posted April 30, 2007 Author Report Share Posted April 30, 2007 You can buy a 12v airsoft battery. <{POST_SNAPBACK}> But motors and gearboxes are ment to run on a lower voltage, can you tell me were you found them, maybe they have upgrade parts to, so a weapon won't fall to bits? cheers Link to post Share on other sites
bullzebub Posted April 30, 2007 Report Share Posted April 30, 2007 high tourqe gears. or else you can get the voltage regulation device from a battery powered drill? Link to post Share on other sites
pugboy Posted April 30, 2007 Report Share Posted April 30, 2007 heya mate as for running aegs on a car battery me and evoracer on here have done it and it works i have a video if your intrested p,m me for more details Link to post Share on other sites

MDK_Marshal Posted April 30, 2007 Report Share Posted April 30, 2007 Yes, a few select and lucky people have managed to run their guns on 12v batteries. The procedure was long and aruous, and it should not be attempted by the weak. You see, these people, they... They.... They went onto the very web of the inter, and quested through cyberspace untill they found that most holy of holy grails... An airsoft website. On this sacred and holy site, they proceded unto the batteries section... and after many hours of searching and battling with daemons, they clicked the "Add to cart" button spoken of in legends of yore. Then the package got held up by a cack-handed delivery company. If you want a 12v battery - GO AND BUY ONE! there are many 12v packs made for airsoft use. Just make sure you have the correct High speed mods, as the battery will push your ROF up for some reason... EDIT - Oh, and to counter the gun falling to bits thing - load of rubbish. Yes, the gearbox was designed to run at a lower voltage. 7.2v, in fact. However, we're not hooking the damned thing up to a van der graff generator and shoving 10,000 volts through it. There is well documented evidence that guns will, in fact, NOT fall apart when a 12v battery is used. There's an obscure-ish tech site where they took a stock TM M4S and ran it at about 30 rounds per second. The only upgrade was a 12v battery and some time lightening and slightly modding the piston. The internals were fine after 5000 rounds. Link to post Share on other sites
pugboy Posted April 30, 2007 Report Share Posted April 30, 2007 we didnt do a single thing to our mp5 to make it run on a 12v car battery just some custom wiring made and a drum mag, thats all Link to post Share on other sites
MDK_Marshal Posted April 30, 2007 Report Share Posted April 30, 2007 Huh. Well, you should probably have lopped the second tooth off, as it usually gets mangled in high speed setups. But, meh. I don't claim to know everything If it works, it works. Link to post Share on other sites
Phatvortex Posted May 1, 2007 Report Share Posted May 1, 2007 Guys this guy is building a gun that is going to be static in a sentry post. For gods sake read his post. I'm presuming the role calls for a massive capacity battery so it can run for days. You may want to try using a MOSFET, it acts like a variable resistor that can handle big loads. If you get the bias on the gate right, just the right amount of voltage will flow across the source and drain. PM me if you want to talk about electronics Link to post Share on other sites

Phatvortex Posted May 1, 2007 Report Share Posted May 1, 2007 Circuit could theoretically be three components. But unless you're willing to try and understand it/ pursue it I wouldn't bother. Link to post Share on other sites
