You should label those to say that, nothing speaks for itself there...

Well i took the plunge and bought 2 6s 5000mah. It will be used in a 12s aerotow plane. Let you guys know when i get them.

I guess there is a problem with the shopping cart software. I placed an order, paid via paypal but the order is not in the history. I'll contact them to see if the order did work.

They already replied that everything is fine and that their IT department will look at the website. Very quick response to E-mails.

Hi everyone, just to correct my above posts - there is no bug with their website shopping cart. I made the boo boo as i registered under my home e-mail address but used my business paypal e-mail address for the payment. I am just so used to using that address that i never even noticed until they mentioned it.
Fast shipping. They are already on their way.

Prices are far too high when compared to Hobbyking.

I just checked 2650mAH 3S packs - 20C which is more than enough for me

Haiyin prices - $16.57 shipped from China
HobbyKing - $10.82 shipped from China or $11.95 shipped from the US warehouse

I've been using the same HK packs for the last 18 months and they are still going strong so for my purposes they are just fine and I do fly a wide selection of foamies and so price is very important to me.

If you are stressing your packs then these may be better for you but at quite a steep price disadvantage.

Parkzone T-28 - 2200 3S
Durafly Spitfire - 3300 4S
GWS Slow Stick - 1000 2S
Flyzone Switch - 2650 3S
FMS Stuka - 2200 4S
HK B-17 - 2200 4S
Homemade W's - 1000 3S
etc...

Haiyin Packs are stocked in the USA, not shipped from China. Prices are FOB Las Vegas NV warehouse. No mark up on Shipping, straight real time pricing from USPS and UPS in America. Wishing everyone a Happy New Year!

Even so, they are still 40% higher than HobbyKing who ship from Washington.

If you can sell a 2650 mAH 4S pack at $15.95 then I'd be interested as I'm closer to Las Vegas than Washington.

I don't a comparison to Turnigy/Nano-tech is appropriate as an "apples to apples" comparison. Like you I'm very happy with my HK batteries (Nano-Tech for me) and don't see any need to shop elsewhere for an equivalent product. However if you compare pricing to Hyperion, ThunderPower on GenAce then your focusing on the real question (IMO). Are these top quality batteries direct from the manufacturer at a discount or simply a manufacturer looking to cut out his middleman for mid range lipo's?

You get what you pay for. I wish I had a nickel for every HK pack that arrived DOA or expired or BLEW UP prematurely. I switched exclusively to Hyperions which are very expensive but are reliable and seem to last forever. If Haiyin can approach the quality of the Hyperions I'm in but I'm not wasting any more $$ on HK packs!

Yep. I never use to think that but these days I'm not so happy with HK batteries, Turnigy in particular. I think they've let the quality slip in the pursuit of ever lower prices.
