ECO-WORTHY 12V/24V 20A Smart Battery Charger for LiFePO4 Lithium, AGM & Lead-Acid Batteries with LCD Display
Product Description
The ECO-WORTHY 12V/24V 20A Smart Battery Charger is a versatile, high-powered multi-mode mains charger engineered specifically to handle modern high-capacity lithium setups alongside standard vehicle battery banks. Built with dual-voltage auto-detection, it allows users to dynamically toggle charging currents to perfectly match the capacity of their leisure or starter batteries. It functions smoothly as a multi-stage charger, a regular battery maintainer, and an emergency recovery tool.
Key Features
-
Intelligent Dual-Voltage Recognition: Automatically detects whether you have connected a 12V or 24V battery bank, delivering a swift 20A charge for 12V configurations or a dedicated 10A current for 24V arrays.
-
0V Lithium Activation Mode: Features a dedicated wake-up cycle for LiFePO4 batteries. If a battery's internal BMS has entered deep discharge protection mode and shut off output (0V state), this charger injects a specialized current pulse to safely reset the BMS and restart charging.
-
Multi-Chemistry Adaptability: Fully optimized with tailored multi-stage algorithmic profiles for Lithium Iron Phosphate (LiFePO4), AGM, and Standard Lead-Acid (STD) batteries.
-
Winter Low-Temperature Optimization: Features a specialized low-temperature charging protocol that uses a reduced maintenance current (2A for a continuous 5 minutes) to safely condition standard lead-acid and AGM batteries when operating in cold weather.
-
Real-Time LCD Monitoring Screen: Equipped with a built-in backlit visual interface that actively displays real-time statistics, including the battery's active State of Charge (SOC) graphic, voltage output, actual charging current, and system fault alerts.
-
Smart Memory Function: Automatically logs and recalls your last selected battery type and custom current settings upon disconnect, ensuring you do not have to reprogram your profile during consecutive uses.
