Hi, just received 3 X 500mAh 14.8 volt from Bangood, is it normal that all are the same, but 2 have swollen by 14mm in size in comparison to another one on the same package.

I would say the swollen ones are effectively scrap and not fit for purpose - you should take it up with Banggood...

You might want to treat the "good" ones with a little caution as well!  They are likely to be from the same batch and/or manufacturer.

You will get a light puffing with age and use, but not with a brand new Lipo. I have a few quite puffed Lipos and although they don't have the current output of a new battery, still give 10 plus minutes on a T-28 Trojan, the older one, but not enough for a more hotter setup.

I contacted them & they sent a return slip & postage.. The odd thing is that the royal mail postage slip they sent says that lithium battery's should be posted according to guide lines. What's the guide.
Maybe this is why Hermes deliver them. "No rules"

I don't think Royal Mail will carry lipos.You will need a carrier,unless they are paying the postage forget it,and get some from over lander which are in England and are very good batteries.

unless the lithium battery is connected to the device it is powering, you will struggle to find any carrier that will take it unless posted by a commercial entity. Certainly they all also specifically prohibit faulty packs which this is.

Ouch!, just seen the price of Overlanders. Will have to go with Turnigy or Zippy on my budget.

Floureon are brilliant batteries,you can get them on Amazon.You have to keep looking as they don't have many sizes in stock.But I would highly recommend.

Got a 6s one off Bangood, came from China, took 6 weeks to arrive and when it did the cell readings were all over the shop. Tried charge / balance which took several hours (i kept a good eye on it in case of problems) it eventually got all readings roughly the same. I left it for a week or so and checked it and once again it was horrendously out of balance - 90%, 5%, 23%, 11%, 88%, 88% i contacted the supplier who asked for proof of a problem so i sent them pictures of the cell readings. Eventually they agreed to replace it `a replacement will be put in the post for you`, another six week wait for the replacement which of course never came. Batteries from China..............not for me angry 2

Zippy packs are great, I use nanotechs in anything demanding and I personally have found them excellent.

I ordered some Floureon batteries (2 x 6s 5000's) from an e.bay seller in HK. After waiting 6 weeks I gave up and got a full refund. Never again.

I think you may have to accept that Bangood know full well the difficulty of returning a faulty LiPo. I expect they will replace them if you can get them back to them. wink 2

I fear you may find the cost of returning them may be more than they are worth.

Find out what it would cost to do as they ask and with that information send them pictures of the swelling and insist you want either new replacements or a full refund.

You have been unlucky.

I have had some Lipo sent from China that have been better and longer lasting than others but never a swollen one from new.

Ah! My apologies to everyone & Bangood that i said earlier that these were from Bangood & in actual fact from eBay. But, we will see if they get back ok & i get a refund. I will now get some from Hobby king. These are being shipped back to Hounslow, west London, which is nearly the same as shipping to Asia. wink

This is a good reason to buy from a retailer if possible. I realise these are now becoming scarce but you can take things back and discuss problems face to face. My nearest is 20 miles away (Al's Hobbies) but any excuse to browse the shelves is always rewarding. I can easily get there and back on 1 gallon of diesel so can be cost effective compared to postage and packaging.
