Experience efficient and versatile battery charging with this advanced 4-slot Battery Charger, designed with a microcomputer management system for independent charging control of each slot. Powered by a DC 5.0V 2A input, this charger supports multiple battery types and offers customizable charging currents to meet diverse needs. Key Features: · Four Independent Charging Slots: Each slot operates independently, allowing simultaneous charging of different batteries with precise microcomputer control. · Adjustable Charging Current: Choose from three charging current levels—0.5A (default), 1.0A, and 2.0A—by simply pressing the corresponding button, providing flexibility for various battery capacities. · Polarity-Free Charging: Unique design enables charging regardless of battery polarity, eliminating concerns about incorrect insertion and enhancing user convenience. · Multi-Battery Compatibility: Automatically identifies lithium-ion (Li-Ion 3.70V) and nickel-metal hydride (Ni-MH) batteries, with manual selection options for lithium iron phosphate (LiFePO4 3.20V) and Li-Ion 3.80V (IMR) batteries, supporting a wide range of battery models. · Real-Time LCD Display: The clear LCD screen shows detailed charging information for each channel, including charging current, voltage, elapsed time, capacity, and battery type, enabling easy monitoring. · 0V Activation Function: Capable of activating deeply discharged batteries with 0V voltage, ensuring battery recovery and extended usability. Note: Batteries with voltage between 1.65V and 2.20V are not chargeable but may receive activation current turbulence type charging. · Safe and Efficient Charging: Employs constant current/constant voltage charging technology with low off-current (<100mA) and minimal no-load standby current (<15mA) to protect battery health and reduce power consumption.
