If you want to build an uber light X-Mag Tom, why not use this to power it. Link! (http://www.powerpaper.com)

I read about this in one of my trade publications. This could really be revolutionary! Here are some specs! (http://www.powerpaper.com/3_technology/batteryspecs.htm)

This is a battery on a sheet of paper.

quite sexy.

i think this a pretty cool idea, not sure about the specs on em, but if they produce enough power to run an emag, then hoot hoot.

1.5 volts per battery...didn't see size specs, but I'm sure they're awfully damned light. Stick a few dozen into a hollow grip, and you could power your gun, your hopper, your radio, your mask, your RC paintmine, your car... Well, maybe not the car ;)

i dont think that they would hold much juice. you'd have to have a lot of those to power an emag! lol

Those batteries have very high internal resistance. And low capacity. High internal resistance means when you fire the gun, the voltage drop will be terriably high. And... they're not rechargable.

We did a lot of research when trying to figure out what would make a spyder fast. The solinoid on the spyder is only 1ohm, so it sucks a LOT of amps at a given voltage.

Something you might considder checking out are LiPoly batterys. They are very high energy density. But, there's a limited amp draw you can take from them before they.. well.. blow up like little baloons. (litterally) And charging them is a pain in the butt. If you charge them in packs one battery will tend to take more of the charge, and they are really sensitive to both overcharging and undecharging.

Oh yea, you can fold, spindle, and mutilate LiPoly cells. :-)

That's nifty...Probably usefull somewhere.

You would need literally 242 of these batteries to make a emag work as it currently setup. Each cell is 1.5V @30mA
you need 16.8V @ 650ma. 650mA\30mA = 22 batteries in parellel for every 1.5v. 16.8v\1.5v = 11 groups of 22 = 242 batteries. This is the same reason you cant start a car with two 9Vs in series. Math sucks don't it, but we can still dream.

Pardon the pun but it looks good on paper anyway....

So does communism. But that didnt work either.

1 mA

Thats not gonna cut it... The Emag needs 8 AMPS at its peak...

I guess if you wanna put 8000 of these things together it would work.

15 Mah...

I dont think this thing would even move the solnoid once...

One CELL in the 14 cell e-MAG BATT puts out over 650 MAH

Do you know what a stock spyder weighs? Something around 1.5lbs....

I heard that the RC guys were having good success with those batteries. I seem to remember something like 5c draw rates. It was at least 2c. It seems like they would work well for an eMag. If you can figure out how to properly charge them. ;)

the emag only draws 3 amps... BUT.... well, a 30 mAh battery wouldnt even begin to move the solenoid. no way in hell. And if, somehow, it managed to cough up the juice, it would only last for like 100 shots. tops.

5c... My idea of high discharge rate is.. oh.. 12c? something like that. I remember discharging my 1700mah batterys in 5-10 minutes. *grins* Those things would get HOT. And there were times the amp draw would peak over 40-50 amps. Mmmm power.

so.. to build an emag battery. you would need 16.8 volts. 5 cells. 18 volts.

To charge them properly, youd need 5 seperate lipoly chargers. OR a very closely matched pack. The cells are to expensive to match like that however ;-) So I think that the multiple charger is ideal.

You'd only need a 10 pin connector to do the charger right. have the charger engage 10 pins as seperate cells to charge, and on the gun use the 10 pins. but wires to make the cells in series. :-)

Make a lighter and smaller battery!!

I personally dont care, and actually like the looks of my new emag w/ batt pack.. but at the field yesterday, my teammates car didnt start.

you want to know what the first thing that came from anothers teammates mouth? "Hey use Dan's battery on his emag. that thing is probably big enough to jump your car"

and it worked.


























jk

lol

but he did say that :)

I remember having a discussion about using these batteries to make an emag battery. Someone (can’t remember who) thought that because these batteries hold their voltage better under a load that 4 cells would work for the emag (14.4 volts) just as well as the current NiMH battery. Do you know if the LiPoly cells are “exactly” 3.6 volts? Or are they just a little more?

Someone needs to try some of these cells. :D

Oh yeah, 12c, are you crazy! ;)

So did capitalism. The jury is still out.;)

If you went camping with your Emag with the new Paper Batteries, you'd always have paper to start a fire with. And i guess you could use the stock barrel to stir up the fire.
