3.7V 1A Single Cell Lithium Battery Solar Charging Controller With Light Control 3.7V 1A Single Cell Lithium Battery Solar Charging Controller With Light Control Description: Product updates, most components replaced by the chip, enhanced functionality. Features: 6V 1A solar charge control module Integrated trickle charge PWM suspension float To prevent lithium battery overcharge Over-discharge to restore a small current charge Industry charging the highest efficiency, a conservative estimate of 98%. Reduce the system from power consumption, improve the charging efficiency Eference Specifications: Enter the photovoltaic panels parameters: 6V 1A (within 8W) Output limit charging voltage: 4.2V Battery low voltage trickle charging: 2.5V Over-discharge voltage: 3V Precision tolerance: 0.05V maximum Reference size: 40 * 23MM Products free of charge a small capacitor, can play the role of filtering. It is recommended to connect to BAT + and BAT- (capacitor long foot is positive) Output terminal specifications: Output: 2.8-4.2V such as low-power lamp beads connected to a series resistor limiting; as connected power lamp beads, to add the constant current driver (normal driver of 12V, unavailable). Please enter in chronological order: 1) LED lights connected to "+ OUT", corresponding to positive and negative. 2) lithium battery connected to "+ BT 'and" -BT ", corresponding to positive and negative 3) photovoltaic panels connected to "+ SOLAR", corresponding to positive and negative Determine any the connection is correct: 1) connected to a lithium battery, LED D1 will light if the battery voltage is too low (less than 3.3V), D1 will flash and exterminate. Colleagues, etc. to the output of the lighting accordingly. 2) photovoltaic plants connected (in normal lighting conditions during the day), the indicator will light D2, and by accompanying by light flashes, such as the surface of the photovoltaic panels during the observation, D2 will be off .
