Pete, Thanks for the detailed explanation. Your exprience is almost exactly as mine. I order 4 x 30C, am told they are not in stock, but am convinced by Julian of the merits of upgrading to 50C for an additonal fee. Arguments that seemed logical to me with regard to over capacity, longevity etc. I also had the 'sponsored pilot' deal, and I too got caught with extra DHL charges and duty, and in the end I just paid them, but I wrote to Julian explaining that this had come as a surprise to me. He said it was clear on his website that there was no VAT, and it was in fact VAT that I had been charged. This was not refunded, but I pointed out that at the time it was not clear on his site. This may be different now of course.
When I reported the puffed pack issue to him the response I got was that it was likely my charger, which did not seem logical to me, as I still have one pack that is still fine, and no issues with any other packs, 3, 6 or 8S regardless. Despite the fact that he said it was my charger he said that he would investigate and get back to me, which is where things broke down, as I never received any further reply.
Today however he has replied to say that it is likely me or my Cellpro 10S that is causing the issue, but that he will help out in a spirit of goodwill. I don't understand how it could be the charger, as it performs flawlessly on my other FP nano ultra packs that I have, and on the one 6S pack that remains fine, and on all my other none FP lipos. I know for sure it wasn't me, as I have been careful to the point of being anal with these packs. I don't know what the outcome of the goodwill will be yet, so I will reserve further comment or detail, but I can confirm that we are now in discussion, albeit with some difficulty as my reply mail today got bounced. I'm trying to look into that so I can send him my reply by e-mail which I prefer. I seem to be able to send mails to others with no issues, so I'm waiting for him to read my PM with regard to a possible mail server issue at the moment, and then we can take the discussion further. I too should like to know how a charger that is well renowned and which has never caused an issue for me before could cause an issue specifically with 6S Ultra Nano 5000 50C packs, and will be seeking clarification when I am able to get my mail through.
Perhaps he could explain for us all what could be the issue?
