How do batteries work?

[Brokenwings]

By the tittle, i mean : Is having more "mah" and V make it a better battery?

I bought myself a gun with a 1500 mah and 9.6v battery. But the website on a little sticker on it says "cheapbattery.com" or something like that...is it that shitty of a battery?

And nun chucks batteries, what's the difference?

Sorry for noobness, but any help would be greatly appreciated. thanks

The voltage indicates how many cells are in the pack. 7 celled pack has 8.4V, 8 cell pack has 9.6V etc... The voltage dictates how fast your motor turns the gears (your rate of fire). The mAh rating is how much "space" there is in the pack to hold power. Higher mAh rating, longer it will last, more shots per charge.

Cheapbatterypacks.com is actually a great website that many people here use to make custom batteries to fit in specific guns. And nun-chuck is just one of the variations of batteries to fit in certain guns. It makes no difference in its performance, only voltage, mAh and chemical composition (nimh, nicd, lipo, life-po, etc...) affects performance.

Wow this is complicated for a noob then o.O
But thanks for making me understand a bit more

Sorry, but your thread title reminded me of this hahah

More mAh = More lifetime
More voltage = More rate of fire
More amperage (c) = More rate of fire

As for that brand of battery - It is not well known

Nunchuck batteries are different shapes to (I think) fit in crane stocks.

If someone could multimeter their batt, I was wondering what kind of amperage I should be getting from a 8.4 1800MAH NiCad.

A multimetre won't tell you amps. To properly test a battery you need a load tester.

Amps (in our case milliamp*hours) = "Juice", how much energy there is in the pack for "work" (ie. turning the motor/gears/pulling the spring etc.).
Voltage = "Push", how much power the batteries (in series) can push through the wires, more voltage = more trigger response and generally more ROF. Keep note that you may need a higher voltage battery to turn tougher springs (as well as a high torque motor/gearset)

Also note that generally 1 mAh = 1 BB fired (or one turning of the gears/motor) but it's not exact depending on environmental conditions (ie. humidity, temp, weather, etc.)

These are INDEPENDENT OF EACH OTHER high voltage does not mean high amperage and vice versa. What I mean by that is that you can have a 12v battery that only packs 500 mAh or a 1.5V battery that packs 2000 mAh (these are extreme examples).

As for "cheapbatterypacks.com", get your batteries from there and there only if purchasing online or from a local RC hobby shop depending on how you feel (ie. support Canadian businesses).

Also keep note that differing gauges of wires have differing resistances. It's suggested that you stick with 18 or 20 AWG wire though because of possible fitment issues when inserting into the battery compartment. A thicker wire will theoretically have less resistance than a thinner wire (of the same material differing materials also provide differing amounts of resistance) however the real "bottleneck" is actually the connector and Deans or Traxxas connectors are what's recommended (use deans since it's a lot more common in Airsoft). You will see a definite increase in responsiveness and ROF if switching from something like a mini tamiya connector to a Deans connector.

PS: Squeenix mAh stands for milliamp*hours ("mA*h") how much charge can go through a piece of wire in an hour while an Ampere is charge per unit time (you can have Ampere*hours as well).

20 AWG? are you serious? All my batteries are 16. I wouldn't go any less than that in an upgraded gun unless you absolutly HAD to.

Actually... you're probably right, it's like .2 of a millimeter difference in wire thickness, I was just thinking that some battery compartments are really tight and can barely fit the battery into it but that's probably not the case for most guns.

I don't know if this was mentioned, but by "higher Mah = more power", people mean, the physically larger your battery is, the faster your gun will shoot.
NiMH cells don't give your motor all the amperage it needs to operate. But larger cells give you more amperage, and therefore higher ROF.
So an 8.4v 3000mah large battery would give you a comparable ROF to a 9.6v 1400mah battery.

Wrong.

Cheapbatterypacks.com is a GREAT site and the Elite cells they make packs out of are awesome.

I chuckle a little every time I see the word 'amperage'.
Come on broskis, its called current!

[ThunderCactus]

+1 on cheapbatterypacks, I've heard nothing but good things
