Tips: Do not use the battery you just received. It needs to be charged before it can be used. Do not overcharge. A single battery cell cannot be charged more than 4.2V. (2S means 2 cells, 2*4.2=8.4V, that is, after fully charged, the total voltage is 8.4V) Do not over-discharge. The discharge of a single cell should not be lower than 3.7V. (2S means 2 batteries, 2*3.7=7.4V, that is, after the power is used up, the total voltage is 7.4V) Do not store it for a long time after fully charging it or running out of power. If long-term storage is required, please discharge the single chip to a storage voltage of 3.85V. And check the voltage every month and charge it to the single chip 3.85V again. Bulging is usually caused by overcharging and over-discharging. It is not remended to continue using it because it may cause safety risks. Someone should watch while charging, and do not charge while sleeping at night as it may cause a fire. Please be careful not to drop it, or overcharge or discharge it to deform or bulge. We will not bear the consequences of such man-made damage.
