RC car battery vs airsoft battery

[Azriel_Strife]

Actually, With a DC Motor reguardless of voltage or capacity of the battery the motor attached will still genereate the same amount of torque. This means that even at 6 volts the battery would still crank the gearbox. it would just consume energy faster, using more apmerage for the torque of the motor.

The only thing that changes when adding voltage is the Maximum RPM of the motor. So you would lose rate of fire, but would not sacrafice any torque. A 7.2 volt pack would be just fine in an Airsoft gun, it would have to work harder because of the voltage drop, but would make up for the extra work with higher capacity as most RC batteries have a much higher capacity for stored energy (IE: 2600Mah vs 600-1400Mah).

To increase torque you need a different motor with a different configuration on the armature. This is measured in "turns". More turns produce less speed but increase torque. Fewer Turns will produce higher RPM on the motor but reduce torque and the life of the motor due to heat buildup.

Hope that helps!

Um...no. I have run several 400fps guns off of 7.2V batteries and with the right cells (4200-4500mAh) they give the same ROF as 8.4V 2400mAh packs.

RC batteries = airsoft batteries

The cells themselves, and thus the storage capacity, are exactly the same. My room mate uses IB4200 SubC cells in his 6 cell (7.2V) RC races. I have an 8 cell pack made from the exact same cells.

On another note, Tamiya connectors, whether large or small, suck. I have seen mini connectors melt and deform from the heat because they are a point of resistance. Large are fine for airsoft purposes in that regard but I have several times seen people scrambling to get the connector back on after it falls off just before a game starts, or fall and hit their gun on a tree and suddenly it doesn't fire. Turns out the impact knocked the wire out of the connector. Don't have those problem with properly installed deans connectors.

necro...

but at the time that tread was made, most ppl where using only NiCd packs and usually the ones that are tagged "Airsoft"

You can just walk in any RC/Hobby store and ask the guy for 9.6 packs. They are used in RC18T truck serie (9.6v mini) and some boats and Monster trucks (9.6v sub-c packs), namely Traxxas E-Maxx and Vilain Twin V

Most people where using NiCd packs in July 2007? Huh?

Oh well, just looked at the most recent post and it said some odd minutes ago so didn't check the post dates on the others.

9.6v RC batteries are quite common and cheap. Grab some 9.6v NiMH and put them in parallel, got yourself a nice battery on the cheap that fits into all sorts of shapes (some work required).

you better not charge them in parallel though.... it will probably fail before it's time...

I find have being in both hobbies(R/C for 21 years,give or take)and Airsoft.I find the R/C ones way better,they seem to last longer! It's a bit over board,but you can get an "R/C" pack thats been pushed and matched,but it's $ and I don't think what we do with these needs that kind of performance.R/C pushed cells were usally set up to give up there charge faster,and I would rather have them hold there charge longer too last the whole game and not carry extra batterys around.But eh,just my opinion,and it's worth just about that lol!
