Using AAA batteries

[bundun]

As my title suggests, I'm wondering if I can use AAA batteries to make a pack.
I know most packs are made up of SubC or 2/3A, but does the size of battery matter, as long as you get enough mAh and V?

Thanks

maybe it wont work, i think under heavy use, while cranking the spring the small batteries wont be able to give the juice that is require to crank the spring, so the voltage will drop and the motor will stop working because there is not enough voltage to make the motor turn.

Can anyone else confirm this? What characteristic of the batteries is insufficient? Because the voltage and mAh will be enough...

im not a batterie expert, but if it was possible to do it like then well the batterie packs we buy would be done with the batteries you want to use.

Intellect makes a pack that has AA size batteries

you can buy rechargeable 2500 mAh AAA batteries at JeanCrottu or similar stores.
I have tried making a battery pack out of eight of them.
you have to make sure the soldering between batteries is extremely good i.e. has a high current flow: for instance, a battery holder like that:


will not work.

be careful when soldering the cells together
I have no way to assure you it's gonna work anyway, I haven't made the final montage yet

Internal resistance.

Yeah, this pack could work (given your voltage is high enough and the spring isn't strong enough), but the ROF will be pretty crap in comparison to a similar capacity/voltage battery of a larger size. The amount of shots you get out of the back also won't be as much either - much of the energy will be wasted as heat due to the amount of resistance in smaller cells. You're also more likely to cook the cells in a high stress application.

Illusion is correct. I have tried this before with AA batteries using a holder. The amount of resistance in the smaller cells was so great fresh batteries could only crank the spring back half way. Then i soldered them together with much better results. However they still do not compare to the 2/3A or Sub C batteries. They simply cant spitout the power thats why they are used for low drain applications such as mp3 players or remote controls. If you look at the specs on the Intellect and Elite batteries they are designed for high drain applications such as RC, airsoft etc.

i dont know much but i "had" a AA battery and it fried in 2 months... shit...it came with the gun.
