battery question:

[gillls]

For a sniper set up, Witch battery would give me a faster reaction from the trigger pull:
A 11.1v lipo or a 12v nimh or a 12v nicad?

[BATMAN]

I used to work for Batteries Plus.  Here's some info I hope helps:

Higher output is 100% dependent upon the specifications of the cells, not the chemistry.  Regardless of voltage, maximum amperage output can differ between batteries.  You can get two batteries that are the same chemistry, voltage, and manufacturer that will perform VERY differently because they have different amperage outputs.  Manufacturers measure maximum output in C-rates, but some retailers will advertise an amp ("A") output rating instead of C-rate (a lot of times these numbers aren't very accurate).  Usually batteries with high C-rates are called something like "high performance," "high drain," or "high output" cells.  These batteries don't offer any advantages to to anything but HIGH drain devices (like airsoft guns or RC cars).  Also, the SIZE of a cell determines its potential for maximum output.  A 2/3A size cell (used in "small" packs), will NEVER be able to output the same amount as a Sub-C cell (large pack).  The smaller cells just don't have as many materials to produce the output.

So when you ask which chemistry will give a faster trigger response, the answer is: any of them, depending upon how high output the cells are.  Each type has many different advantages and disadvantages.  However, it is getting to be more common for Li-Po batteries to be used these days as high-output batteries because they have such high energy density; they output a lot of power and hold a considerable amount of capacity in very small-sized cells.  It is easy to find them with high-outputs (sometimes higher than you'll EVER get an airsoft gun to use), but they're also expensive, and not very resilient (or stable for that matter) in comparison to NiMH and NiCD.  Hope that helps.

You better have some legit fuckin internals in order to make that gearbox last...

A lot of us have gearboxes that can handle much much more than that... and are just curious.
As a rule of thumb, lipo's have considerably higher amp-out ratings... so they're going to give you the better trigger response.
That being said, a large 9.6v with a high amp-out rating is all you'll ever need for trigger response unless you're pulling an m170 or so.

Trigger response is pretty much ROF..it's how fast that motor turns those gears that turn that piston...and how fast the piston flies forward is the spring.

Then what is trigger response? :idea:

[axisofoil]

Trigger response is the time between pulling the trigger and the first shot.
ROF is the continuous firing rate.

Trigger response is about current ramping (speed of battery/wiring to go from no current draw to maximum)
ROF is about continuous current draw.

Both are reduced by bigger springs. Trigger response is reduced because the current must ramp higher and faster. ROF because there is more required current to keep the gearbox turning.

They're related, but not the same.

So comparing batteries,

12v 2300mah battery like the one listed below:
http://cgi.ebay.com/12V-2300mAh-NiMH-Ba ... 4ceb93e85b


or a 11.1v lipo 2300 mah:
http://www.airsoftpost.com/product_info ... s_id=29612

Witch would give me a higher trigger response im looking for. I am thinking ill be running a systema magnum motor with either a m160 or m150 spring.

Thanks for your opinions above, and thanks for any toher listed advice below

lipo

[axisofoil]

Which is better? Lipo.
Will you notice a difference? No.

Here is the deal, the LiPo will only charge to 4.25*# of cells ( so 3 ) thats 12.75 volts.  That 12V NIMH will charge to well above 14 volts and then average out to around 14volts after the initial "over charge" (If you will).

Trigger response is NOT soley ROF.  It's a combination of Torque and RPM.  Both together determine the Trigger response.  Torque is determined by the power output of the battery pack.  The LiPo certainly has more power.  Power is Current * Voltage... Assuming the listed voltage of the packs... the 11.1v is 11.1v * 27.6 amps or 306.36 watts of power.  The 12v is 12 * 23 amps (figuring 10C for NiMH packs) or 276 watts of power.

I suggest A LiPo, but not THAT LiPo.  There are hundreds of much better LiPo's out there.  You need to find a LiPo that's (mAh * C rating)/1000 is closer to 45 (this will give you the amperage of the LiPo) above 30 is highly recommended.  Those packs are ideal for airsoft use as they will provide all the power your motor needs to operate thus generating the best trigger response.
