What is the story on Air Thunder lipos?
Are they holding up any good? Is anyone here using the 6S 5000mah packs for trex 600?

I was very skeptical myself but after reading the reviews at trex tunning and some others from here, I decided to give them a try. They are every bit as good as they say. I use them on my Trex and I am able to run them until it wont lift anymore and they charge right back up to 2150mah with no issues. I have drawn them down to 8v and they charge right back up to 12v. I get about 10-12 min flight times out of them with no puffing or heat problems. I have over 25 cycles on them so far and going strong. I would Highly recommend them. I don't see any of the premium batteries that can do the same without damage.

Get them and try them and you can be the judge on them. They give you a 30 day guarantee no questions asked refund if you don't like them or if they don't perform as expected. It also has a 90 manufacture guarantee. So far they are my battery of choice!!!

Jay if you keep drawing that much power from them they are not going to last very long. You should leave at least 20% of the capacity in the battery if you want it to last. When you can feel a big power drop, its time you land.
On the main story of the 6s battery , I've never heard of "Air Thunder" but the Thunder Power battery's are great and even better when used with their charger and balancer.

If youve never heard of them then you shouldnt be giving advice pertaining to them.

Air Thunder's biggest claim is the batteries ability to COMPLETELY discharge to voltage cutoff and sustain NO damage!

Cant speak for the 6s on the T600, but im using them on my Ion-X and E-stratus as 12s1p 5000.

You gain flight-time but you will get higher weight instead.

Main thing is that you can skip the timer, so if you fly soft or hard you get maximum flighttime regardless.
(for me its an extra minute 30 seconds if I fly soft practicing funnels and such things)

Dont have enough cycles yet to say if they hold up, but after 10 cycles down to where its no point flying any longer they hold voltage equal to my flightpower and better then my TP's.

Do they make any 6S lipos less than 5000 mah? I'm looking for...say...3700 - 4600 mah for my Logo 10. I'm concerned with the 5000's being to heavy for my stretched L10 3D.Trex 500, Stretched Logo 10 3D, Ion-X, Gaui 200

They are relatively new so I dont doubt that they will be releasing several more battery types in teh future.

With the way these things are performing, I bet they take over the market in short order.

It also begs the question: why havent other lipo manufacturers been able to develope lipos with the same types of performance?

KongPower is also out there, my guess its the same factory in the background though.

I'm sure that Air Thunder is keeping their "formula" under wraps. It's just a matter of time before Thunder Power, Flight Power, and the others reverse engineer their packs to determine their design.Trex 500, Stretched Logo 10 3D, Ion-X, Gaui 200

Airthunder, Thunderpower, Flightpower....

None of them make their cells, they merely assemble packs.

the cells are generally made at a central plant in Asia somewhere.

Many of the different pack brands actually contain the same cells...

In order for Thunderpower and Flightpower to get the same packs, they are going to have to start doing business with the same cell manufacturers that supply Airthunder.

If I read right, You can put in a order for special packs. Not sure the cost on those. For the price, I think they are going to be a pretty good battery. Thunder power took a bit to prove themselves but now they are well known and respected.

Umdpru, is correct that they don't make them themselves. It does come out of Asia just like the others but they have their own brew of material for their cells. Others are not far behind. Just look at Apogee's lithium metal batteries. They seem to be doing pretty good but I don't think they can claim the same performance as air thunder. I am sure in time others will be doing the same deal.

I figured that much but I'd bet that each manufacturer has their "proprietary" info. Not so much Thunder Power and Flight Power but my point was that Air Thunder probably has a tight lid on their particular design. I'd even bet it's made in a different facility.

Perhaps what TP and FP could do is go back to their existing manufacturers and provide them specifications similar to those that AT provided their cell maker.

Gyronut, given everything I've read about AT, you won't be disappointed... and when you dutz it in and mangle your pack AT will take it back at 50% purchase price

The answer to your question is they have not been out long enough to give you a good answer. These are preliminary findings.
I have two Airthunder 6s5000 packs and have flown each three times. Pack #1 so far has the punch of a TP and a 6 minute flight time with 5254mah recharge last flight and ballances nicely. Pack #2 so far is weak in the punch and only flew 5:15 minutes with 4683mah recharge last flight and takes longer to ballance. Both packs were over 150 degrees F at the end of the flight. Keep in mind the ambient temp here is over 100*. Before drawing conclusions though, I would like to get more cycles and see if pack #2 will come around. If not I hope Airthunder will replace it. The self discharge rate seems rather high. After two days both packs needed almost 200mah each to top off the charge. In compairison my Hyperion needed only 80. Again, these packs are not fully broken in yet.
As nice as it is to have a longer flight, it is traded for LOOOOOOONG charge times. Because the battery drains so low my TP1010C goes into "initial charge" mode and stays there quite a while. It takes an average of 1:15 minutes to complete the charge.

In conclusion, Good sport packs. The key is how long they last and we wont know that for a while. That being said, I am not ready to buy the company yet, but I may get a little stock, so to speak.

And, my batteries didnt take full charge until after cycle 3 or 4
First cycles I ended up with something around 4700, now Im up to 5200.
