RE: Anyone else buy some bum HK lipos lately?
HK has undoubtedly witnessed countless returns of packs that are without problems. I have no problem with the warranty personally because I use the same initial 3 second procedure they use. If the pack passes this test then 99% sure it is a good pack. The key to an initial pre-check is in number 7. "Please balance your packs if your packs appears to be unbalanced" and would go well to handle over 90% of the problems I see posted on this forum. There are countless posts that clearly indicate that a user doesn't understand a distinction between series charging and balancing.
It is bad that you have trouble with 2 packs already. If you don't want to jump thru the warranty hoops or are too late then perhaps someone here on the forum can assist you with the 2 packs.
ps. My last 2 batches of packs were equal voltages for all cells (about 3.8-3.85)
