I'm basically saying what the manufacturers are stating. They claim a treu 25C continuous discharge and 50C bursts. KongPower also makes a 5000mAh pack. I like the 2200mAh because of its weight. It kind of gives us the edge when we race those nitro bullies.

What dimensions are the 2200s?

And how much per cell for a small order?

Here are the dimensions for the 11.1V 2200mAh:

Size:110(L)x34(W)x28(H)mm
Weight:195g

I'm still testing the KongPower packs to see how well they will suit the vehicles. I know readyheli.com is a distributor as of now.

Any new news on this?

I have (6) 3S 2200Mah Air thunder batteries for my Trex 450.

Another great thing about Air thunder and Kong power is if you do puff them/damage them, they will replace them at half the cost.

So Air thunder http://www.airthunder.com/ sells the 3S2200 Mah for $65:

and Kong power sells the 3S 2200Mah for $65:
http://www.readyheli.com/Kong_Power_.../kp-2225-3.htm

From my understanding, Air thunder came out first. then Readyheli started selling the kongpowers afterwards. That made Air thunder put this statement on their homepage: "Recently, one of our competitors has been spreading untrue rumor about us, claiming they manufacture our packs and implying we have inferior products. AirThunder hereby dispute any such claims. etc. etc. etc" you can read the full thing at the air thunder homepage.
Here is official release from airthunder where their packs come from:
http://www.helifreak.com/showthread....ght=airthunder
I have no Idea if they are the same as kong powers. Any one else know?

This was a good thing for us consumers because it brought the price of these packs down about $10 since I first got them.

Also if you read this: (note this guy is sponsered by kong power, but it seems to be the general consensus...)
http://www.helifreak.com/showthread.php?t=50464
He logs 3 seperate of the kong power batteries.
he comes down to the conclusion that the best way to treat these batteries is just like any other LIPO, obey the 80% rule (means if you have a 1000mah lipo, you should only be putting 800mah back in the pack when you charge it.) and the other thing is charge is at 2C or below. He was charging one at 3C and that seemed to damge the battery fastest.


I just like to not worry about ruining some batteries if I discharge them below 3V per cell.

Kongpower and Airthunder both buy cells and/or packs from the same manufacturer. I have packs from Kongpower, but I also have packs from another supplier that might use the same cells. I ran that pack in my Ofna buggy with great success and it was able to deliver 128A bursts and I ran them for 23 minutes on grass. The only problem is that this one supplier didn't provide me with references and I don't want to dump a few thousand and then nothing arrives. I asked them for NET terms and they wouldn't agree with a NET15 and I usually work with NET30 from my suppliers of electronic components. All I can tell you is that if I had this supplier send me the packs, I would be able to sell much cheaper then Airthunder.

Another heli site that has jumped on the band wagon of no puff lipos

They are called Lightning Power, same spec, price, so im sure they are the same packs as air thunder and kong power:

I would have placed an order from the supplier I have, but they wouldn't send me any trade references. All I can say is that my prices would be around $50-55 for the 3S 2200mAh packs. You can see them in this video:

In the first post you can see I ran them for 23 minutes.

legobrains 01.23.2008 07:26 PM

People who bought from them. It's basically a way to find out if your supplier is what they say they are and will actually deliver the goods after you send a few thousand deep one to them.

Wow. Keep us posted on this Lutach. I'd be interested for sure. Looks like these cells have a lot of potential, especially in 2p configurations.
