Is 7.4v 20c/3000mah reciver battery enough for Airsoft?

[blackjack21]

I just ordered a lipo rated for 20c discharge (40 burst) and 3000mah, 7.4v

Someone told me that reciver batteries are no good for airsoft as they dont put out enough power. But if my math is right this battery will put out 60 amps.

Is there anything I am missing here?

alot of formally trained GunDocs can agree with me on this i hope, in that if it has a 20C output, doesnt neccesarily mean that your gun will pull all 20C from the battery, it just means the maximum output of the battery is 20C, alot of things will count toward your rate of fire, gearbox shimming and motor height, motor speed, airseal, connector type, etc. if you figure out what your guns demands are and test a few batteries out, you might get a better idea of what works.



PS. I'm no gundoc, please feel free to correct me as needed, this is just wat i think.

Well, except if the company is known to lie on their battery specs, any 20c 3000mah is equivalent to another, no matter the brand. "Someone" was either misinformed or thought you ordered a weaker (Less C or mah) battery pack.

This pack should be enough for anything but a high torque high speed build.

EDIT : As sammy said, a lot of factor can affect the amount you can draw, but a 20C battery stays the same from brand to brand unless, as I said, they lie on the label.

You might benefit from posting a link to the battery info/source...

Also...PM Dynamo...he'll know. (tell him that I refered you)

[blackjack21]

Here is the battery. seemed legit to me. It is the perfect size and has the most MAH I could find (I am running a SAW, not intersted in crazy ROF just want MAH)

I will be getting it soon, maybe I can review it.

You should be good to go with that (as long as you switch the terminals nicely).

Just the general words of advice
...don't use mini tamiya (or even large...best to go with Deans or better)
...careful when switching connectors...don't short out the pack
...always charge with the balancing tap
...with a new battery in your setup...until you get to know how it's working, check it periodically to see how it's holding up and discharging.

+1 /\

Also on hobbyking, if you hang around on the page for a while, they'll offer you the item for a dollar less , just noticed that!!!!

[blackjack21]

Thanks!
This will be my first lipo.
I always convert to deans and have a good guy that will do it for me.
I have a balance tap charger already picked out....

Echo all above.
Also, that brand is good shit. The output should more than suit your needs.

Why I never managed to open the hobbyking website...
Everytime I get redirected to the http://www.hobbyking.com/ra.asp?z , then 404 not found.

Even if that battery looks fine, it's a bit underpowered.

It is about equivalent to a small 1500mAh buffertube pack. Yes, it will work, but probably not for SAW purpose.

The pack is a 2s2p. That means that it's actually two packs (4 cells). And since it's rated 20C constant, it means that theses cells each are rated 10C. That is not much for a sustained fire pack.

This pack is a lot more suitable

[m102404]

Excellent catch on the 2s2p! My mistake!!

[blackjack21]

So does that mean this double pack is only going to give me 30amps as opposed to 60? 10c x 1500mah for each pack x2 packs? This still should be doable as most 9.6 nmh only run about 22 amps...


Sadly those bigger packs are too big for my gun, this was the only one over 2200mah that would fit...

[K3vX]

While searching for a good NON 2s2p I found this:

Anyone can explain to me what is that battery?
Even being 2s2p, it's still two times 32.5c at 2100mah... seems overkill for that small package?

Or, something normal that could fit, based on the original pack :

Just get two if you feel you lack the amperage needed for the day.

FYI if you can add a mosfet to your SAW it will make your battery efficiency ridiculously good
I'm getting around 400mah/box mag on my 249 with lipo/mosfet/triple torque gears at 1400rpm and 380fps
