Wow, that sucks!
Glad the packs you got were all in good shape, I would weight the batteries in groups like it's been said, and if the shipping label has the total weight printed somewhere on it, you should be gold.
However, after jumping through these hoops, I would ALSO send them a copy of all the statements from previous orders and show them how much you buy, and since the shipping shouldn't be a big deal for them from their local warehouse, they are total idiots if they don't just eat the shipping themselves and send you your 21st pack.
If they give you any flack, just contact paypal and make a claim. Usually that will get the attention of their supervisor and THEN they might start treating you right. :wink:
I'm really surprised that they have sent up to 10 - 15% bad packs in the past!!
Definitely helps to buy from a local warehouse that way they can't hold you hostage with the shipping from China.
Hope my 2 6S 6000 mah Nanotech packs come here with no issues, you have me nervous now! :lol:
I have only bought motors and Nanotech packs from HK, and so far, everything has come with in a week or two, and nothing has been defective, but since they only stock the International (Chinese) warehouse with Nanotechs (far as I know) I can't get them locally.
Also, see if there is another channel to contact HK other than the email that you received, when my Golden Motor wasn't coming on time, I talked with the only person who seemed to be available, someone who was there to answer technical specs on the motors, and they made it happen all the while, the "official channels" weren't even answering my emails.
Dig around a bit, I'm sure that you will get someone who will help ya get your last pack!
That order amount alone should make them realize what a valuable customer you are!
Good luck!
