So I'm looking on Hobby King at 11.1 lipos and there are a lot to chose from, I'm looking for one that is 20-40, I know KWA doesn't recomment anything over 15, anyways does anyone know which battery (single pack) for rectangular area & (triple pack) one battery to fit into each hole of crane stock is the largest dimensionaly that will fit and still be able to latch butt end, I usually have the stock extended at least 1 click if not 2, I don't have the gun with me as I'm out of town but looking to buy a battery so it's waiting on me when I get home, thanks

I may be mistaken but I have not seen any 11.1V lipo that's nunchuck configuration on HobbyKing. And all of their brick packs are too large for the butt plate on KWA crane stocks.

This battery fits perfect in the butt plate of the crane stock.  http://www.hobbypart...hort-asoft.html

I looked at the 2.0 on HK that you have pics of but those look like 15-25c, I'm looking for 20-40, or 25-50

Simple question here....why are you looking for a higher C rating?

Higher "C" rating is to protect the battery, not to fry your AEG motor.
The motor will only use the amps it needs not what you give it. ex. i have a night light it on all the time. must cost nothing to keep on all year, When i use my miter saw the house lights dim. It needs more power the night light doesn't.

If your motor uses 23amps and the battery is 60amps it will only use 23 amps of of the 60 thats available, so the battery is protecting itself. As opposed to a 20amp battery & a motor that wants 23amps, that will cause the battery to stress.

There is a chance if you use a 60amp battery & something jams it will shoot up to 60 amps through the gun and cause damage to a number of electric parts.

The reason KWA recomends a 15c or lower is so the motor will not get the amps it really wants (dim lights in the house). Therefore not tearing up your internals.  If you got the $ (to fix it) give it all the C's it wants and let us know how it performs. Would like to do that,  backup m4 is not ready for my SR10 to go down right now.  Im going to start with that little one Hellcat suggested, call me chicken :) .

It wil stop at the amps it needs, Just like charging your iPhone in a car with a battery that has 700 amps. Fuses!

This is a 12 amp power supply, connected  to a 1 amp lightbulb. Using a Amp meter you see its only using .8 amps NOT 12 amps
The lights take what they need/want to work. If he connects more bulbs it will draw more amps as needed.
Adding a higher C rating battery doesn't mean it will sent more amps then the motor will draw




Deans battery discharger old school nicads (10 2amp bulbs) discharges at 20amps, because there is 20 amps of bulbs, Sending 50amps int the discharger will draw 20 amps due to the maximum amps of the bulbs

Well thanks for the input, Anyone use the Deans connectors that hobby king sells, or the alarm for the lipo batteries to keep from draining the lipos down to nothing, I was looking at those today

Buy WS Deans there the real connector, Since AEGs don't use a speed control there isn't a LVC, using a alarm is a good idea. Lipos can go into a "Deep Discharge" if this happens it can't be reversed, the battery is then useless. Some say 3,0V is safe i cut them at 3.2V

I use this http://www.ebay.com/...=item2a271f5dee Im not sure if it reads each cell or the two cell pack.

Its hardwired on the battery wires so its always connected. I only use lipos. Don't know what will happen using a nimh battery

I used to be able to go directly to Deans and buy 50 pairs at a time.  I don't know if they still do that.

Here is the the link for the batteries I use... 11.1 1600mah 25c... I run a Lonex A1 motor which recommends a 25c to run it... I get 31 rps on fully charged battery on stock gears with a G&G M130... I have run them on the KWA motor, and the motor gets pretty hot so that is your decision only you can make... And yes you need to put Deans on... It is a much superior connection... I have used the knock off deans in the past and the do perform fine but they don't connect and disconnect as smooth as the real deans... Spend the extra $1 or $2 and buy the real ones... You'll be much happier and not have to worry about pulling out a wire because the "Deans" are so tight...

Your battery suggestion doesn't help him at all. He needs to fit the battery inside the crane stock and this will not fit. It's far too big.

As for Deans connectors, they sell 2 packs of male & 4 packs of female. Really no need to buy full sets. As the Male goes on the charger & gun(s) Female goes on the batteries. Most hobbyists use more female then male.

Make sure they are WS Deans
