Newb time (battery questions)

[15thKnight]

Before I go and blow a good 30-100 CDN on a couple new battery's, I have a couple questions to ask.

First and formost, If My AEG has a 1,200 mAh 8.4V Battery, Can it take, say a 1800 mAh battery. if so what will happen (im expecting a faster fire rate and some damage but wish to clear this up.)

And the last question. I know that batteries (no brainer here) are reactive to metal. but is it ok to put a small battery on top of the gear box
(in this case a old kraken ak-47 placing the battery in the case on the top)
will this damage ether the battery or the gear box in any way?

thank ye for your time airsoftcanada.

Any battery is fine to have with an AEG.
The higher the volts, the stronger the pull and faster rate.
Want it to the fastest? Li-po.
Nothing will happen ontop of the gearbox when placing the battery there. People put stick batteries there.

thank man. oh byany chance do you go to defcon games?

well, for simple start.
8.4 v 1200 mah vs 8.4 3800 will not shoot faster, only last longer.
the v makes gun shoot faster, not mah.

edit - though when you hit a certain size of mah, the battery requires more cells, thus making the battery larger in actual size, so your location may not be able to hold it.

I've went once. I have no time to go on Sundays since I got school next day. lol

KhaosGott- ok thanks

hitman - its pretty much im in the same boat. I wana go there one time but :/

Yes it will. It'll shoot a TON faster. A large increase in mAh will also have an affect on rate of fire, not just voltage.

The reason for this IIRC is that the larger cell has the higher discharge rate.

That's correct. Or at least part of it, I'm not an expert

[15thKnight]

so there is no damage to the motor/ with a larger mAh amount?

No, not really. mAh can increase your gun's rate of fire, but more generally you can start damaging things with higher voltage, meaning higher speeds/wear on both mechanical and electrical parts.

Ok thank you . and I have to say this noob tank without the flaming is acually getting me information ive needed instead of And I do quote

I use a G&P 8.4v 2200mha stick battery in the battery tray under the top cover for my AKs, lot's of power to go all day. But the gun needed some mods in order for it to fit.http://www.uncompany.com/pageproduct...p?prodid=10218

ROF is determined by voltage and amperage.

The motor will draw a certain amount of amperage but it is limited by how much the wires can carry and how much the battery can supply. Stock guns often have I believe 18awg wire which can carry an average max of 10A. Even stock TM motors can draw up to 15A I believe so the limiting factor will be the wire. Small batteries like a 1200mAh one can only usually supply around 12A tops. Better guns will have 16awg wire which can carry around 13A of current. Some people rewire their guns with 14awg wire, I found some 12awg wire online that is as thin as standard 16awg wire, you need a lighter to melt the insulation off since a wire stripper will remove the outer layer of wire strands.

Higher mAh does NOT mean higher ROF. Lower internal resistance in the battery cells means higher amperage supply means higher ROF. The ELITE 2000mAh 4/5A high drain cells I use outperform ELITE 5000mAh SC cells. Higher mAh usually means lower internal resistance because of the larger cell size but not always. Higher amperage supply also means better trigger response as the initial motor start up requires a lot of amperage to provide maximum initial torque. A lower available amperage supply means the motor accelerates slower so the initial shot will have a longer lag than the space between shots on full auto.

Remember, voltage is pushed by the battery, amperage is pulled by the motor.

LiPo are nice but the highest ROF is with a larger voltage. A 12V NiMh will reach around 16V when fully charged. Or you could go for a 14.8V LiPo, or a 24V NiMh pack, etc. etc.

Oh and you can run a li-po fine with your AK, v3's are much stronger. Also depends on your spring what you have set inside.
