Magsz Posted June 5, 2008 Report Share Posted June 5, 2008 So much for madbull having exclusivity. Hrmph, i wonder what their discharge characteristics are like. Link to post Share on other sites
jafoca Posted June 5, 2008 Report Share Posted June 5, 2008 Those are very interesting. They are similar shape to nicd/nimh but similar quality to lipo. It looks like they would fit well in a buffer tube on an M4. I have LIPO batteries for RC airplanes and the thing that keeps me from using it for airsoft is that the different cell shape prevents using them in many common configurations. This changes that a lot. Link to post Share on other sites
Magsz Posted June 5, 2008 Report Share Posted June 5, 2008 Thats not a typical lipo bud, its a lif4 or something similar. Its not lithium polymer. Link to post Share on other sites
dgsgc Posted June 5, 2008 Report Share Posted June 5, 2008 Any idea what lenght they are? As jafoca said, they look like they would just fit in a fully adjusted m4 slidign stock. Link to post Share on other sites
jafoca Posted June 5, 2008 Report Share Posted June 5, 2008 Thats not a typical lipo bud, its a lif4 or something similar. Its not lithium polymer. I can tell they are not normal lipo - that is what my comment says. I wonder if the chemistry is similar to a123 batteries. a123 systems It really looks cool - who wants to be the guinea pig?

davedawg123 Posted June 5, 2008 Report Share Posted June 5, 2008 Hrmph, i wonder what their discharge characteristics are like. I'm pretty sure they are 12-14C. At least, that was the typical discharge rate of 18650 LiFePO4 batteries when I was researching them before. They are similar shape to nicd/nimh but similar quality to lipo. It looks like they would fit well in a buffer tube on an M4. 18650 = 18mm diameter x 65mm length per cell Multiply that be 3 and you get around 200mm not including connectors and such. That's about the same as an 8.4v 2/3A pack. At best, they may work in buffer tubes with stocks fully extended only. If you want buffer tube batteries with lower ROF (there already are 11.1v lipos that fit), there are 18650 10-12C li-ions in the works. 3.7v per cell so only two are required and can power 450ish setups. Should be able to keep all but the fully collapsed stock position. Link to post Share on other sites
DWells55 Posted June 5, 2008 Report Share Posted June 5, 2008 Oh man, you had me excited until you said "all but the fully collapsed stock position." All I want is a 7.4v battery that fits in the buffer tube. If it can match the RoF of an 8.4v NiMH and is good for 1200 - 1500 shots, I'd buy two of them. Link to post Share on other sites
Utty Posted June 5, 2008 Report Share Posted June 5, 2008 I wonder if the included charger is safe to use? Link to post Share on other sites
Mig1 Posted June 5, 2008 Report Share Posted June 5, 2008 What do you mean? The buffer tube does not collapse. The stock slithers up and down the buffer tube. Regardless of if the stock is expanded or collapsed, the buffer tube is always the same length. Link to post Share on other sites
EmptyChambers Posted June 5, 2008 Report Share Posted June 5, 2008 Nay. The thing is that alot of the stick batteries protrude from the buffer tube slightly. Thus necessitating the need for the stock to be open. Link to post Share on other sites
davedawg123 Posted June 5, 2008 Report Share Posted June 5, 2008 Uh... who said anything about buffer tubes collapsing? Link to post Share on other sites
M0ldyM!LK Posted June 5, 2008 Report Share Posted June 5, 2008 I think he's referring to people saying some positions of the collapsible stock won't be functional. If it's inside the tube, it should have no effect on it. Link to post Share on other sites
uscmCorps Posted June 6, 2008 Report Share Posted June 6, 2008 So much for madbull having exclusivity. TSI had LiFe batteries long ago for their Galils. The ones I had weren't very reliable though so it's back to NiMh 2/3A for me. Link to post Share on other sites
Viking Posted June 6, 2008 Report Share Posted June 6, 2008 I just ordered a couple. I ordered the 3 cell split. I normally use Lipos but they are getting too much for my 3 round burst mosfet ( from extreme-fire.com ). I was waiting for these to be available for a long time. Here they are now.... yay !!! Will let you guys know how they work ... Thanks Arvin Link to post Share on other sites
MDK_Marshal Posted June 6, 2008 Report Share Posted June 6, 2008 Quoted from RSOV, for the people who didn't bother to read the product decriptions 'Morepower' New generation high discharge rate and safe 9.6V 1500mah LiFePO4 battery pack comes with 110/220VAC input battery quick charger with LED indicator. Dimension of cell is 65mmx19mm. Check out the LiFePO4 battery characteristics here ; http://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery So they're 65mm x 19mm - SHOULD fit in a buffer tube without too much fuss, especialy if you get the 2+1 pack and lop off the extra one.

But wouldn't chopping the a cell off leave you with a woefully low voltage of 6.2v? Link to post Share on other sites
jafoca Posted June 6, 2008 Report Share Posted June 6, 2008 But wouldn't chopping the a cell off leave you with a woefully low voltage of 6.2v? ya... i don't think I am understanding him correctly either.... the charger they are selling with them scares me. Link to post Share on other sites

If it's inside the tube, it should have no effect on it. Yes indeed, I do not see how one could easly shoulder his M4/M16 with a lithium-stick coming out of the end Has anyone actually fit a 7.4V lithium inside a stock tube, allowing to close the cap on it?

my_plague_666 Posted June 6, 2008 Report Share Posted June 6, 2008 how will the 9.6V LiFePO compare to a 9.6 NiMH ROF wise Link to post Share on other sites
terrorist killer Posted June 6, 2008 Report Share Posted June 6, 2008 OMG 12.8v If anyone who has pimped out a gun so it can fire at like 40rps with a 9.6 buy one of those, think about how many mags you could empty into someone and how quick that would happen If anyone could make an AEP take a systema turbo and accept these batteries, man that would be awesome AEP + 12.8v bat + systema turbo = Dualie uber ownage it would use a high cap mag every two seconds though and as standard the original mag is fired off in that time Link to post Share on other sites

I've got a gearbox that throws out 0.2's at 330 on the nose, and does so at around 13-15 rps. With a 4.8v 600mAh pack. 6.2v's perfectly fine! =D Link to post Share on other sites
