Among the key features of AirThunder batteries is the ability to withstand over-discharging. Over-discharging has been a major issue with conventional Li-poly technology as it leads to over-heating, deformation, and degradation of the battery. Model aircraft owners are often advised to time their operation to avoid detrimental effects. Our proprietary formulation and packaging technology has circumvented such problems, allowing the battery to be safely discharged to low volt. This is an industrial-first; a true breakthrough in Li-poly technology. In addition, our battery maintains its voltage till the very end of the discharge cycle. This means you can fully enjoy your flying experience worry-free.

I'll be interested in hearing as well. Considering some packs for my Blade 400.

Bump. :)

Still hoping someone has experience with these.

Seem a bit pricey. For that amount you can go with Flightpower, which are tried and true Enerland cells. AFAIK the best around at the moment.

Well I think they are great. True to their claim, great people to work with too. We have dropped all other lipo brands except for Air Thunder and Dualsky. Both brands stand behind their products.

The advantage to the AT over everyone else is that they don't puff, swell, and can handle constant over discharge. That is why you buy Air Thunder.

I'd love to see some graphs to prove this.

*edit* i see they have discharge graphs on their site. That's very cool, and more than I can say for some LiPo manufacturers. Worth further investigation, i'm sure.

I just picked up two 7.4v 5000 packs, I'll keep you posted. I have no intentions of over discharging though.




83gt -> RE: Anyone use the new Airthunder packs (4/10/2008 4:44:51 PM)

Hrm. Looking at the graphs, I'm wondering how they can call this a 25C constant pack. The 5000mAh cells drop to about 3.2v on just a 20c load. I'd think a 25c load would take them below the level of most LVC's, and any sort of burst rating is shot to hell.

Flightpower Evo 20's hold around 3.4v with a 25c load, and they are 20c rated cells.

Interesting indeed. Seems they may be a rated a bit optimistically.
