FS: many 3.7 6A LI-Poly batteries

First you have to know how to charge and discharge the Li-Poly batteries, you can see the tips from www.edogfight.com. The Max charge voltage for 3.7v Li-Poly cell can not exceed 4.2V and the Min discharge voltage for 3.7v Li-Poly cell can not less than 3.0V

These cells are 3.7V,6000mah, 150g, 190mm*74mm*6mm. I got these cells from Apower in China, they told me they test them on 4C continue discharging current without any problem and upto 5C,6C also no problem but they didn't test them. They said the discharging current can be 40A burst. My quick ep 10 helicopter has not been arrived yet, so I can not test them. I think for Eolo, eco 8 or maybe logo 10 will be ok, because current of logo 10 only around 25A when hovering and 40A burst, right?

The price is only $19.99 each(less expensive than Tp 3.7V 2100mah cell but triple capacity). You can make your 4S 6A pack for only $80!!
The shipping of first 4 cells to most countries is $19.99 for express mail(1-2 weeks) and for UPS or Fedex world express $39.99(I highly recommend this you'll receive your batteries in 3 days). And for each more cell add $2.99 for shipping.

I accept money order, bank transfer. I preser using the www.westernunion.com after you send the payment tell me the Money Transfer Control Number (MTCN). Then I'll ship your items.
Thank you. Feel free to contact me: ted616@vip.sina.com

How do you wire these up? I don't see the welded on tabs. Do you have to use the Aluminum solder?

They are normal Li-Poly batteries.

See there are two big tabs on the left in the second picture.

You can just solder the tabs like you do in other RC batteries. You don't need special soldering equipments.

Wow, those are huge - I doubt they'll fit in any small airplanes. Helis and BIG planes, tho - might work...

How much do they weigh, and how much would shipping REALLY be to the states (I know that I can send stuff this size to Canada from here for just a few bucks)

Also, do they give full capacity at the stated 4C continuous discharge?

Soooo,

A 3s 11.1volt 6000mah pack, weighing about 16ozs, measuring just inside 7.5"x3"x.71", delivering from 24 to 36amps is available for $60US? Great!!!!

I would like to test this in my Lazy Bee with both the Astro Flight brushless 020 geared 3.3:1 w/ 11x7 to 12x6 props(well within amps limits) and the Astro Flight brushless 05 geared 3.3:1 w/ 12x6 to 13x6.5 props(pushing the upper amps limits).

E Zoners need to see how well these will work in real situations. Please see the following as an example of a very successful E Zone experience.

http://www.rcgroups.com/forums/showt...threadid=66171

You will note in the above that there are also EZoners that can do much more objective testing for you.

Also, please consider Paypal payments and some less expensive shipping arrangements and you will have a winner here.

Best of luck, Steve.

Flightofsong - in english units we're looking at a cell roughly 5.3 oz, 7 1/2" by just shy of 3" by 1/4". You're right, they're not for small planes.

Ted, I think Weflyon is right on. These batteries look very interesting, and it would be good to see some tests of these packs - both electrically and in . There are some excellent battery wizards in the Power Systems forum who might be able to help out in the testing department.

Also, I'd like to second the suggestion to please consider Paypal and less expensive shipping charges—even if it means the batteries are really $25 each instead of $20 each...

Thanks,
Chris

Ooops... missed the weight in the initial post.

These look really intriguing, but the lack of any test data and th high buy-in cost due to the shipping charges are holding me back at the moment.

I want a four pack or two.
Will you consider charging actual shipping charges ?

Notice, the shipping charge is less expensive than actual shipping charges because they'll be shipped from China and you can calculate the shipping cost from ups or fedex website how much for the US-CHINA world express that's around $50.

Sorry, I just found out I didn't change my location, I am in China now. And you are send the payment to China and I'll ship them in China. Sorry!!!
And if you are buy from other US dealers you also need to pay shipping cost, only the cost is less expensive.
I am not using the paypal because paypal is not safe for sellers and it charge too much fees.
Thank you.

And the Air mail is cheaper, but the post office told me that will take about 2 weeks to 4 weeks. The price is only $9.99 for the first 4 cells. I don't think anyone want to take this one.

Yes it is, as long as you send the product there would be no reason to dispute it.
