the "C" rating indicates the the maximum current draw from the pack, or how quickly you can discharge the pack.
In this instance, this pack has a maximum constant discharge of 30c, so 2.2A (2200mAh) x 30 = 66A.
It has a maximum Peak discharge of 40C, so 2.2A x 40 =88A (peak denotes a 10 second burst)
I hope this helps.
That all depends on the size of your motor and esc. Bigger motor will typically draw more amps. Should be in specs when purchasing motor. Buy an esc rated to that many amps or more. The higher rated esc you buy, the less the esc will struggle and the less heat will be produced.
Well if you have 4 motors they likely won't draw as much power. But it still depends on the combination of esc and motor. When you look at a motor, it should tell you "Max Amps". My general rule is to take that number and then add 10 to it, then buy an esc rated for at least that many amps. This is important because if you don't get a big enough esc for your motor, your motor will stop when you try and go full throttle, possibly resulting in a crash. Also if your esc is barely big enough for your motor, it is very easy for it to overheat and cause problems.
I took the "Alula-Eva" for a little bit of slope soaring.... And the 3s 2200mah lipo kept it running for more than 6 hours that day...!!! :) The "Alula-Eva"whas still a little bit to light with these wind conditions, so i had to add about 40 more grams to make it more stable.. so a bigger lipo would not be a problem at all... I got a lot of questions about the "Alula-Eva", So... if anyone likes more info on the "Alula-Eva", Please read the description of this video on YouTube..!!!.......>> Thank You <<......
Atenció*n si compran por esta pagina el envió* es por medio de Fedex y el costo de la baterí*a sera de el doble como mí*nimo, ya que los señ*ores de este sitio declaran el costo del envió* como parte del monto total. Tengan cuidado y compren por otros lugares que no realizan este sistema!!!!!
i recieved 3 batteries last week on 25/8/2009, one is very good and balances well, the other two batteries had one cell each that read below 2.5 v. these cells don't charge over 3.9 v causing the overall voltage to drop very fast, the readings of one battery when i recieved is:
Cell 1 had a voltage of 3.85v charged up to 4.20 v Cell 2 had a voltage of 3.86v charged up to 4.18 v Cell 3 had a voltage of 1.9 v charged up to 3.9 v

25 thumbs up!
Good value for the price but only 3 stars because I suspect performance is a little overrated. Great when fresh but noticeable loss of punch midway thru flight. Now beginning to swell (just a little) after about 15 cycles. Also heavy and bulky for the capacity.
Used on Precision Aerobatics Katana MD and Addiction with appropriate IPAs and props. Never been discharged under 11.5v. Max draw on either plane 40A, well within spec for the battery.
Ordered 2 packs.. One had a bad cell on arrival.. The 2nd fly well in yhe Easy Star but requires balance charging after each flight as one cell drains a bit faster then the rest. .1v lower when discharged.

I checked the capacity with a constant load of 20A and the result was exciting: 2220 mA and the drift of the cells was quite low. Also lipomon from rctool.de fits well to the balancer connector.
