For you, apart from changing the name of your sales account, nothing will change. Below on the photo is instructions on how to find an argnet seller. Li-ion battery charger 7,2 - 7,4 V. The value of the charging current can reach up to 2A so that the battery with a capacity of 3000 mAh will charge in 2 - 3 hours and the battery 1500 mAh will charge in 1 - 1,5 hours. The charger includes two highly efficient power modules and four modules supervising the charging process of battery cells, thanks to which it equals the quality of charging for professional chargers. The charger is also distinguished by the ability to start charging batteries deeply discharged even from 0 V, which is rare in cheaper chargers. The charging process is indicated by two red LED diodes visible through the ventilation holes of the housing, while when the charging is completed, the red diodes go out and the blue or green ones light up. User manual in Polish. The charger charges the batteries using the CC/CV method, which is required in the process of charging lithium cells and ensures im a long service life. CC is a constant current value until the charging current voltage reaches the maximum permissible value (4,2 V per cell or 8,4 V battery). From now on, the charging process goes to the CV phase, i.e. at a constant voltage value, the value of the charging current begins to gradually decrease to 0,1 A, followed by the end of battery charging. The figure on the right illustrates the process of charging the Li-ion battery. Punkt A is the beginning of charging, punkt B is the change of the charging phase from CC to CV, while punkt C is the end of charging. The red chart is the value of the charging current and the blue chart is the value of the charging current voltage. You will connect a battery to the charger that has a JST XH2,54 charging connector visible on the photo on the left
