Bought 7 of these to make a 20S 13.5Ah e-bike pack and have one spare brick. The price was 60 USD a piece, a real bargain for 35C cells. 5 stars for value.
The box was damaged but cells arrived intact and well balanced, all within 3.82~3.85V, ready for paralleling. Thus 4 stars for quality.
Now comes the deal. These are NO WAY 35C cells. Tested them today and they sag violently given their rating. On a 55-60A controller the sag was as much as 4 volts, which almost equates the sag of my 3yo 20C 10Ah Turnigy hardcase pack. Don't get me wrong, these are still good batteries, but they are more like 15C, not 35C as advertised. I really wanted to like them and was expecting close to 1-1.5V sag, but the reality was shocking. Come on HK!
