Aundhegrtt Quad Switching Module Constant Voltage/Current, High Power Automatic -Boost

2. Robust Components: 7 MOSFETs! (4 for power conversion, 1 for input reverse connection protection, 2 for charging reverse charging protection) 1. **High-frequency, low-resistance solid-state capacitors for input and output filtering! High cost! Low ripple!** 3. **Professional battery charging:** The constant voltage and constant current output voltage and current are adjustable! It also features a high-efficiency, low-heat, high-cost MOS-type reverse-current protection circuit! Safe and professional! 4. **Comprehensive protection functions:** Input reverse connection protection (using MOS components/high efficiency), Input overcurrent protection, Input undervoltage protection, Output reverse current protection (using MOS components/high efficiency/high cost), Output short-circuit protection. 1. Truly High Efficiency and Low Heat Generation: High-performance architecture, synchronous rectification for both boost and converters, typical efficiency 95%! 5. **Rich indicator light functions:** Red and lights illuminate during constant current output; light only illuminates during constant voltage output; and green lights illuminate when the battery is nearly fully charged; green light only illuminates when fully charged!
