Thanks to the YouTube user "TheKetsa" who noticed that no more such 'Cheap' batteries on HobbyKing, and it is my mistake - the paper I am holding was 'fabricated' paper by offering option from HobbyKing to 'cheat' on customs, so prices are actually not correct. Sorry for that.
Just be careful when dealing with LiPo batteries. It can provide lot of current, enough to cause fire. Aside that, please use "hobby-grade" charger, or watch charging time. Do not charge longer than say two hours... This battery has NO internal overvoltage protection circuit as is the case with stock battery for Eachine H8. Also, it is not good to keep charged batteries for long time as I did (whole month remained fully charged).
