budorange Posted December 23, 2008 Report Share Posted December 23, 2008 budorange Did you managed to fit a mosfet in the tube with that battery. no, I've one but I'm still undecided on which gun to put it in. even though I think it would be quite hard to fit them all together.not impossible.

Madfingaz Posted December 24, 2008 Report Share Posted December 24, 2008 I use Li-pol... it really increases your rate of fire. Link to post Share on other sites
FaRKle Posted December 25, 2008 Report Share Posted December 25, 2008 I use Li-pol... it really increases your rate of fire. It depends. A 7.4v lipo won't increase ROF much over a quality 9.6v pack. Which is nice. Link to post Share on other sites
bankz5152 Posted January 6, 2009 Report Share Posted January 6, 2009 I dont really want to trawl through 20 odd pages of text so i shal ask my question. Can I install a 7.2v Li-Po battery into my current 9.6v configuration, fully upgraded internals. Thanks alot Edit - To FaRKle - a plugged in a 7.2v li-po into my P90 which was running a 9.6v configuration bosted the ROF a noticable amount. Link to post Share on other sites

If you're that lazy, I doubt you'd take care of a lipo properly. But to answer your question, you can. I had a drop in ROF in my KWA M4 (380 fps) vs 9.6v. But if you take the time to READ you'll learn much more. Link to post Share on other sites

Clot Posted January 6, 2009 Report Share Posted January 6, 2009 Hi peoples, I am gonnay do a super noob ignorant lack of search post. So apologies in advance. I am now using 11.1v li-ion firefox batts in my ak's, they are VERY good, my kalash and vfc's can handle them very very well. I am just wondering about the charger, I have one of those really ###### small ' auto balance charger ' thingys. I start to charge and rig up my meter, the voltage seems to skip between three different voltages which differ constantly. Now I assume that to be the balancing thing doin its stuff on the three cells. I know I want a 12.6v peak on the pack when its fully charged.. It can go way above, or way below. and changes all the time. What am I lookin out for in this instance of keek chargerdom ? I will be spending the cash very soon at my local hobby shop for a proper lipo charger to suit. But in the time being.... help Thanks people.! Link to post Share on other sites

Thanks alot Edit - To FaRKle - a plugged in a 7.2v li-po into my P90 which was running a 9.6v configuration bosted the ROF a noticable amount. Sure. Heck you could put a 22.2v lipo in there if you wanted too. There are things to consider, and I'd end up rewiring the article to talk about it all. Just because your setup is fully upgraded doesn't mean it'll last. I've been running a bone stock Dboys SCAR on a 7.4v 30C cell for months, but other than bad shimming, the most important bit was already taken care of by DBOYS. If you don't have proper AOE, your rig could die a painfull death. OF course, if you're already running a 9.6v the 7.4 shouldn't make much of a difference. Heck, if you had a good 9.6v the ROF might even drop a tad with the 7.4v BTW, it's 7.4v not 7.2v if you're talkinga bout a lipoly. They are 3.7v per cell. Link to post Share on other sites
bankz5152 Posted January 7, 2009 Report Share Posted January 7, 2009 Thanks alot. I just plugged in the 7.4v li-po and the ROF is much higher than when i was using a 9.6v has more of a kick as well. I was going to re-wire to 14 AWG in a few weeks time. At the minute my P90 is MOSFET & 7.2v li-po and full guarder & systema internals with 14 AWG wireing. Been the past 5 months been brillaint hasnt had a problem. Link to post Share on other sites
sorehammer Posted January 8, 2009 Report Share Posted January 8, 2009 Can any one reccomned what lipo would be suited for a A&K M249 Para please i looked around but can't find any reccomedations. Link to post Share on other sites

Well, what are you looking for out of it? Mine is a high ROF. I'm running a G&P M120 motor, 350fps spring, systema high speed gears and an 11.1 25C 2200mah ThunderPower Lipoly. this fits easily in the handguard and lasts me all day long. You could probably put a larger 7.4v lipo in the handguard if you wanted to. Link to post Share on other sites

mrbishi Posted January 9, 2009 Report Share Posted January 9, 2009 just finished reading the articles lad, outstanding work. id been humming & hawing about making the changeover to li-po & mosfet for ages but thats made my mind up. im currently using a stock dboys cqb sd wit a fire fox 9.6 3000 mAh in a crane stock and have never had an ounce of bother with it but i have always wanted burst fire & a faster trigger response. over here the limit is 328 with a .2 i.e. 1 joule. my question is, am i better off upgrading the motor, gears, piston ect first or just going li-po & mosfet and wait for things to fail? im not after insane rof & cant do high fps, i just want quick trigger response & 3 shot burst, along with all the other benefits of li-po. im guessing these arent suitable due to hi voltage & low fps set up: http://ebaybanned.com/product_info.php?cPa...roducts_id=1881 http://ebaybanned.com/product_info.php?cPa...roducts_id=1770 i know theyre cheap shít but im on a very tight budget, global economic turndown and whatnot.....or shud i just stick with my original battery & try sqeeze a mosfet in....... somewhere thanks Link to post Share on other sites
infected Posted January 9, 2009 Author Report Share Posted January 9, 2009 I'm not a fan of the firefox batteries myself. One thing I will tell you is that a mosfet doesn't give you 3 round burst. A microcontroller does that. I don't make microcontrollers, but there are a few guys out there who do. You don't have to replace those parts in your gun, but you can. The most important thing is that your shimming is right on. I ran my Dboys SCAR for several games, with it in stock condition on a 7.4v lipo with no ill effects what so ever. In fact is looked nearly new inside and the piston had almost no wear. If you want fast trigger response, a mosfet is a must have, and an 11.1 might not be a bad investment. Your limiting factor in full auto (ROF) will be the rpms of that stock motor... they aren't very high at all. Link to post Share on other sites
pistonhead Posted January 9, 2009 Report Share Posted January 9, 2009 Hello A friend of mine bought the same 11.1v 25c thunder power lipo infected has, it is amazing!! makes his completely overhauled cyma Thompson sing He's running... Guarder sp120 echo 1 version 6 shell guarder metal bushings Guarder polycarbonate piston Guarder aluminum piston and cylinder head Guarder m4 length cylinder Modify reinforced high torque gears(MUCH better then guarders) Extreme Fire Wiring Infected's mosfet Deans and a Matrix 3000 Motor (torque model) Guarder tappet+nozzle Guarder steel spring guide No AOE correction Because I don't feel like destroying his piston by accident MY question is does anyone see any weak points in this setup? Thanks Link to post Share on other sites
infected Posted January 9, 2009 Author Report Share Posted January 9, 2009 Personally, I don't like aluminum piston heads, as there really is no use for them. They just beat on your gearbox and internals more than necessary as well as increase noise. I would also fix the AOE. Link to post Share on other sites
ST19AG_WGreymon Posted January 9, 2009 Report Share Posted January 9, 2009 So a 7.4 Li-poly will be just as good, if not better than, an 8.4v NiMH? I'm thinking of getting one to replace the stock battery that will come with my D-Boy AK-74. Will a li-poly give me a bit faster trigger response? Or do I really need a mosfet? If someone would please direct me to a 7.4v stick-type li-poly battery for my D-Boy AK-74 that would be cool too. Link to post Share on other sites
infected Posted January 9, 2009 Author Report Share Posted January 9, 2009 A 7.4v lipo will perform better than most 8.4v packs. You'll likely get better trigger response given the ability to put down more current, but a lipo is really need or you could char and burn up your trigger contacts and you'll either end up with a low ROF, or a worn out trigger switch. How long that will take is anyone's guess. Link to post Share on other sites

infected Posted January 9, 2009 Author Report Share Posted January 9, 2009 The micro-controller is the brain that controls when the gun shoots and when it doesn't. That gives you the three round burst. The mosfet is.. well a mosfet. Most guys who make the microcontroller boards also have mosfets on the board as well. They are a good bit more expensive though. The firefox batteries just aren't proven, and we don't know who's making them. There's no track record either. I prefer using batteries from companies that have a reputation in the R/C world, as those radio control guys really beat their batteries up a good bit. On top of that.. all these "Airsoft" batteries are surrounded by so much hype that turn out to just be false dreams and smoke and mirrors. I just ordered another ThunderPower pack myself (literally just ordrerd it). The guys at Rclipos.com have the 2250mah 30C 7.4v for only 49.99 SHIPPED. Pretty good deal here in the USA for that battery. Link to post Share on other sites
FaRKle Posted January 14, 2009 Report Share Posted January 14, 2009 If you want fast trigger response, a mosfet is a must have It also depends on what motor you have. Some motors you won't notice a difference in trigger response between a 7.4v lipo and 7.4v lipo with MOSFET (Magnums), but other motors (notably the more voltage hungry motors) you'll notice a difference. Actually, some voltage hungry motors (such as the SRC Ultra High Torque/PEUSA motor) get better trigger response and ROF off of a 9.6v 2700mah battery than a 7.4v lipo with MOSFET. I've found Magnums to be very versatile motors that work very well with lower voltages (7.4v and 8.4). Link to post Share on other sites
