【4-Bank 12V 5A Battery Charger】 The upgraded 12V lithium battery charger is equipped with 4-channel alligator clips, with 5A output per channel, enabling simultaneous charging of four batteries and saving up to 75% of charging time. DC Output Voltage: 14.6V (LiFePO4), 12.6V (3S NCM), 14.7V (Lead-Acid). Charging Current: 5A; Total 4-bank output power: 240W; Conversion Efficiency: ≥87%; Rated Input Voltage: AC 90V–240V, Frequency: 47Hz–63Hz. Each channel is independently charged, detected, and controlled.

【Intelligent Charging Technology】 The 12V charger can customize charging curves for different battery types, automatically switching between constant current (CC), constant voltage (CV), and float charge modes. After a full charging cycle, the charger will shut off and enter float charge mode, continuously monitoring battery voltage. It will automatically resume charging when the battery level drops below 80%. You can leave the charger connected permanently without unplugging it from AC power.

【IP56 Waterproof & Efficient Heat Dissipation】 The 12V lithium charger features a fully sealed aluminum alloy casing, providing IP66 waterproof, dustproof, shockproof, and corrosion-resistant performance, with excellent heat dissipation and fanless silent operation. It has a wide operating temperature range (-20℃～40℃) and ensures stable performance even in harsh environments. The product has passed rigorous cycle tests and underwater operation tests, making it ideal for marine and outdoor use.

【Dual-Color LED Indicators & Auto Memory Function】 The 12V lithium battery charger is equipped with two sets of dual-color LED indicators for real-time charging status monitoring: Green Flashing: Standby / No-load / 0V Battery Activation Red Solid: Charging (0%~99%) Green Solid: Fully Charged (100%) Red Flashing: Fault Alternating Red & Green Flashing: Mode Selection The charger automatically recalls the last selected battery type when powered on, with no need to reset.

【8 Protection Functions】 This 4-bank marine battery charger features a comprehensive protection system: Output Over-Voltage, Over-Current, Over-Temperature, No-Load, Short-Circuit, Reverse Connection, and Over-Charge Protection.

【0V Activation & Trickle Charging】 The 14.6V LiFePO4 battery charger can activate lithium batteries protected and shut off by the BMS. If the battery has not been charged regularly for a long time, it can wake up deeply discharged 12V (12.8V) LiFePO4 batteries with BMS protection and restore them to normal voltage. When a lead-acid battery is nearly full, the charger automatically switches to trickle charging mode to help extend battery life and repair batteries with sulfated plates.
