Problem with ZIPPY Flightmax 5000mAh 3S1P 30C

[Alfa Spirit]

Hello,

I bought at Hobby King two Zippy Flightmax 5000mAh 3S1P 30C and never used them.

One of the two Zippy Flightmax have a problem : one cell is inflated , here' s a picture.

How can I proceed? Thanks

How long have you had the cells?
I would contact them and send them your picture for an attempt at replacement.After that your best bet is to tear the pack apart and see if you can salvage the good cells.This is a good example of why I don't trust there batteries. I have seen a few reports of Zippy/Turnigy/Rhino showing up with a bad cell right out of the box.

ive had mine puff after a long hard run, after it cooled it was fine.

I will send an e-mail to HKwith the picture. I bought them a set of Turnigy 4500mAh and a set of Flightmax 5000mAh. Only one cell is inflated but this not my fault.
Do you have experience with HK support?

They are usually prety good about support it just takes awhile because it's in China.

A swollen or "Puffed" lipo is bad bad bad.....

The lipos contain chemicles that react with one another.The reaction is controlled.
This reaction can cause amperage in excess of 100 amps.People weld with much less.
When the containment process starts to break down=Puffing,well,it's up to you....

So if it has unswelled is it fine to use? or not?

No,I would not use lipo's that Puff

Lipo Fires,I dug this up over at RC Groups someone has documented Lipo fires by causes.

Charging puffed cell causes it to ignite (93)
Charging slightly swelled pack causes fire (83)

Now this LiPo is outside my home, I don' t want fire in my house

Do you know the process with HK support? Thanks

[hydromaddicted]

Yes, there's a support link on the top of the HK home page

But and it's a big But, I found this
8) Should you be too concerned about sending the parcel back to us due to safety reasons. We will not warranty the pack. Purchasing any battery from HobbyKing.com, constitutes an agreement to this warranty policy.
Each battery brand has it's own warranty time limit. Our standard Lipoly warranty limit is 30 days, unless otherwise stated in the product listing.

The problem is that Zippy Flightmax LiPo is new, no charge and no discharge. I' ve got five other batteries but only this one looks dangerous
I hope that HobbyKing will do something

Looks like you've cut the red connector?
