Thanks for the update. It is useful data. Lucky for me, all the battery I got are online and they work. I will rephrase- my battery that was marked Pisen runs good and I have another in the order line too.
From what I know of LiPo, how it is charge for storage are contributing factors. Rule of the thumb is cycle them and don't buy them to keep. They will die especially if you do not use it. Regular charge will help. Once it over discharge, the probability of it being dead for good is very high. There are tricks you can do to resuscitate it but not for the faint heart. You end up burning down your house if you do not know what you are doing. LiPo battries are not forgiving.
Most reasonable quality LiPo specific chargers must have inbuilt charge control parameters. No big secret now unlike the early years. You will know - if it does not... very likely, you will have to live in the streets after that!
Just do not allow the battery to short circuit during transit. A lot of the story we hear of battery exploding in the pockets is due to improper transport. Most new battery has the connecting tabs deeply recessed to avoid such issues.
