I apologize for this inappropriate remark.
I'm trying to get an overview of all the currently available technologies of Li-Ion batteries on the market. But this manufacturer and the type of battery has long missed my attention. I had the prejudices that it was just another Chinese variation of the useless crap battery. But after about a month of intitial testing of Swing 5300mAh battery cells It seems that I could not be more wrong. Most of parameters listed in the datasheet are achievable and in most cases are even better in real life conditions. After first 50 cycles of my already completed cycle life tests it seems that the cycle life parameters from datasheet are also correct, which can make this cell one of the most robust cell of the market of small prismatic/cylindrical cells. Even LG HG2 (which is one of the best cells based on my test procedures) is outperformed in some parameters.
