According to the latest reviews this cell is even the best-ever cell of "AW IMR 18650 2000 ma / h", far superior. Thus, so the current best cell on the market. Finally there is this cell even with Button Top that with three points on the normal Flat Top cell welded by the company Enerdan in Germany wird.Dadurch that here no new, additional plastic cover is needed, the cell remains beautiful "slim". I use a battery carrier ProVari the company Provape / USA. Here one needs an battery cell with Button Top.
