Bare lipo cells good & bad

One the hunt for high density cells for a UAV project.

Preferred cells would be these
http://www.maxamps.com/proddetail.ph...8-Pack&cat=361
us$300 a set + shipping

Being the cheapskate I went looking for a cheaper alternative.

Ordered a set from here
http://www.batteryspace.com/New-gene...3.6V-10Ah.aspx
(33*4) $132 + $95 ship

Performed to spec.
Well packed.
Arrived real quick, ordered Friday, arrived Tuesday.
USA > NZL

Marginally better than the ones I was using.
2 in parallel.

Got some custom made from a Chinese supplier.
Took a while due to being custom made.
I commissioned 8x cells.
Came to us$95 shipped
First shipment got returned due to volume of lithium in package.

Shipped again with only 2 cells.
Arrived damaged
Both cells punctured due to poor packing.
And inspection method at DHL.
Will be giving them a call tomorrow.








I know you get what you pay for but come on DHL.
You are not singapost


edit:
Looks like something got lost in translation.
My order got changed from 8x to 2x without my knowing
Even though my last communication for for 8x.
At no point after that was I informed only 2x was produced,
Oh well, welcome to Chinese business I guess.
For the trouble I don't think I will bother DHL as they will just cite poor packing by the supplier.

Try talking to FMA Direct. Pretty sure they will build a custom pack.

Any FYI you don't want the maxamps battery. Their "True 40C" means 40C burst, so only about 20C continuous.
