It also constantly monitors the safety of the charging status of the connected batteries. You can both lead-acid batteries up to 6 cells, as also connect NiCd,NiMH batteries 1 to 10 cells. With a precision multiturn potentiometer you can adjust precisely and individually the end of charge voltage in the range 1,4 to 15 V at. If the preset end of charge voltage is reached, the module regulates the charge current automatically reset and thus protects the battery from overcharging. The charge current can set with a multi-turn potentiometer in the range from 10 mA to 500 mA - optimal to the battery type.   input  5 - 20 V / DC · final charging voltage from 1.5 to 15 V adjustable · current limit of 10 - 500 mA adjustable
