The lithium packs are made of cylindrical 18650,26650,14500,21700,18500,18490,14650,18350 cells, with excellent energy density &low self-discharge. The battery pack built with PCM which can protect battery from over-current, over-charge, discharge,short-cut. Also, assembled with cables connectors for directly use. The battery pack is made from cylindrical cells in series or in parallel.(like 2P1S, 2P , 3S, 5P2S, etc) There are so many pack styles according to customer鈥檚 requirements. Our professional engineer will give you full power solution ! Environmental and safety characteristics of pouch cell battery pack Overcharge testNo fire, No explosionThe cell is discharged following the standard discharge method. Apply a 5.0V power supply and a 3C charge current until the charge current drops below 0.02C. Over discharge testNo flame, No fire, No explodeCell shall first be charged according to standard charge method锛宎nd then cell is to be discharged by 1.0C current to 2.50V; then cell is to be short-circuited by connecting the positive and negative terminals of the cell with copper wire having a maximum resistance load of 30鈩?for 14days.
