Replacement battery for the eMag

[hitech]

I have a replacement idea for the eMag battery. It would be 5 ozs, last longer on a charge than the original battery (850 va 650 mah) and is up to the current draw of the emag solenoid (capable of 6 amps, the eMag draws 3). Drum roll....

It would be two PQ35S-850 batteries from here (http://www.battlepack.com/polyquest.asp) wired in series.

You would need a new charger/system. Anyone want to try and build one?

Yeah, you. :P

Um, it's no prettier and looks no smaller, so what the hells the point?! Do you just want to hack up your gun?

Do you know how much the eMag battery weighs? This would save more weight that the xValve. How many people thought the weight savings was worth it then?

Going from my X-valve to a classic was quite a difference. Don't they have volt regulators or something like that? If there was a way to hook it up to a regular wall outlet and have it regulate down to get a charge but not blow a battery then you'd be in business. Do I make sense or am I just rambling again? Or is that your question and I just repeated it?

[warbeak2099]

Would they both fit in the battery pack? Then all you'd have to do is wire it all.

It would require a properly built charging circut. I'm not sure at the moment exactly what that would require. However, they do sell over charge protectors.

Yes. Together they would be about 0.8 x 1.5 x 2.7 inches, plus wiring...

[AGDlover]

well i dont know about you guys but i'm happy with what I have now I really dont have the time energy and money to be wireing and BS

[Beemer]

weight you talking? I dont have the numbers.

How much weight you talking? I dont have the numbers.


I don't know what the eMag battery actually weights. But it feels like about pound. It's 14 AAA cells. Someone weight 14 AAA nimh cells and tell us what they weight.

[trains are bad]

you can make a basic charger very easily and cheaply. All you need is the correct size resistor, and probably a diode. And one of those big powers supply plugs that plug into the wall.

Not for these batteries. :nono: You would end up with a fire doing that. :wow:

I hate numbers and now I find a want for them.

[Jaan]

Custom battery packs are easy to make, and chargers are easy to come up with. My friend / boss Stuart Cody is as good as it gets at this stuff:

Give him a call.

Does he work with li-poly batteries? They have special charging requirements.

I couldn't stand the uglyass heavy battery, why I sold my Emag cheap.

[Beemer]

ya ya we know do some push ups.

I still need the numbers.

Okay, I shouldn't try and do this from work...

Using the PQ3S-600 instead we would have slightly less capacity (600 vs 650). Considering the voltage curve is probably better and the initial voltage would start slightly higher the usable capacity should match or exceed the eMags battery.

The weight of this cell is 44 grams (X2 = 88 grams). The battery weight would be 3.1 oz.

I found data on AAA nimh cells that weigh 12 grams (X14 = 168 grams). So, the weight of the eMag battery should be 5.9 oz (doesn't seem right, but hey, that's what the numbers I found claim). So, the weight savings is a little less than 4 oz. :( However, that matches (or beats) the weight savings for an xValve. :D

The weights for the AAA cells don't seem right, but until I can find something with different numbers...

:cheers:

EDIT: With a little less capacity we could get the weight down to 2.3 oz. :D

[Beemer]

:cheers: Like I said I hate numbers, but 4oz or a little less is about or almost 1/4 lb. Thats huge. Thanks for the numbers HT

sounds good to me as long as the batteries dont rattle around in the housing.

[WARPED1]

BUT, the current housing is the fugliest part!

[mcdkid]

it looks ok, and is a great grip

[TheTramp]

I love the way the battery pack for the the E-Mag looks and more importantly, feels. Of course I've got big hands so smaller doesn't = better.

There's no way I'd spent the cash for two of those batteries to save a few ounces. IMHO you'd have to have to have little girly arms and tons of cash to make it worth it.

[WARPED1]

Make the damn battery round!

[hitech]

Those batteries could be used as is in the existing eMag battery pack. That's good for those of us who like it. :D

Li-poly batteries can be made in varying shapes. Customed shaped batteries could be made that would easily fit in a round fore-grip. At only 1.5 inches wide, they would fit in some existing round fore-grips. :D

[Duzzy]

You are forgetting someone or something...

Just talk to Rogue and see if he will make you some "stubby" e-mag foregrips...

If you could get the battery idea off the ground I would hazard a guess that he might be interested...

[RFLMN1]

My standard battery pack weighs 3/4 of a pound, if someone could make a lighter pack I would want one.

Jason

Is that 3/4 of a pound include the aluminum housing or just the battery?

[RFLMN1]

The whole pack

Jason

[Big'n slo]

Battery alone = 6.3 ounces (http://www.automags.org/forums/showpost.php?p=1710183&postcount=12)

According to RF

I'd be up for a lighter battery.

[Ohms Law]

Big'n Slo (or RF) is correct. The complete battery pack with housing and hardware is just over 12 ounces.
The housing and hardware is 6 ounces.
The battery cells is just over 6 ounces.

How about a flat cylindrical battery that slipped over your air tank? :cool:

[Tunaman]

The emag battery alone weighs 6.4 oz. You will need some specialized soldering equipment to solder these up. I checked into that equipment and it is just not worth it. ;)

[hitech]

The li-poly batteries do not come in cells the same way other batteries do. It comes as a "pack" with two wire leads that should be solderable like any normal wire. :D

[hitech]

So, anyone want to try and build one of these? I'll answer any questions I can. Anyone...

[11 Bravo]

Has anyone looked into this further?

[r-unit]

i hope they do..im interested.
