3S Lithium Battery Charging Charger Module MPPT Solar Panel Controller LED Power Description:100% Brand New and High Quality3 series of lithium battery charge management 2000MA The maximum power point of solar tracking function Module Size: 50mm*25mm*9.5mm Characteristic： 1. The maximum power point of the solar cell tracking MPPT, automatically adjust the output voltage of the solar panel to the appropriate value, so that the solar panel output power to maintain the maximum; 2. Can be a section of lithium iron phosphate battery (3.6V), 2 lithium iron phosphate battery (7.2V), 3 lithium iron phosphate battery (10.8V) for a complete charge management; 3. Complete charge management for 1-cell lithium-ion battery (4.2V), 2-cell lithium-ion battery (8.4V), and 3-cell lithium-ion battery (12.6V); (Default delivery is for 3-cell lithium-ion battery) 4. Use two current sense resistors in parallel to enhance the cooling capacity and the ability to pass the current; 5. Set the resistor on the back of the charge board to connect the 8th pin to solve the problem of trickle charge current is small; 6. Charging status and charging end status Dual indication (red light on charge / full green light on / red light flashing green light indicates that no battery is connected); 7. Battery overvoltage protection. 8. Use fixed-value high-precision resistors to avoid uncontrollable errors when using adjustable resistors. The fixing holes in the module are designed according to the standard terminal size (7mm pitch terminals), and the terminals can be soldered to facilitate wiring. 9. The PWM switching frequency: 300KHz 10. The constant current charging current is set by an external resistor (default 2000mA) 11.The state of charge and charge to end the state of double indicator (when charging, the red light, Full charged: the green light, red light flash. Green light is often bright. There is no battery) 12. 16V-25V solar panels, suggest 18v 10w solar panel. Application:The use of solar energy battery charging The notebook computer The application of standby battery The portable industrial and medical instrument The electric tool A separate battery charger Photovoltaic maximum power point tracking (MPPT) Photovoltaic maximum power point tracking (MPPT) is to ensure that the changes in light intensity, maximum output power of photovoltaic cells has been, in order to make full use of solar energy. In general, the need to achieve MPPT function with a switch mode DC-DC converter, product keep the output voltage and charging current (output) maximum, as in the linear mode, high voltage will be converted into useful work, released in the form of heat, so the linear model to achieve the maximum power point tracking does not necessarily ensure that the solar energy utilization efficiency is relatively high. CN3722 is a step-down switch mode DC-DC converter the photovoltaic maximum power point tracking function, the input voltage up to 25V, is very suitable for the input voltage and the voltage of the battery is used large.
