DUOYI 14.6V 40A Smart Lithium Battery Charger for 12V LiFePO4 Batteries: Fully Automatic, Fast Charging with OV Wake-Up Mode and 2 Connection Methods

DUOYI 14.6V 40A Lithium Battery Charger Features: 【8 Protection Functions】: Our lithium Battery charger integrates 8 protection features such as overvoltage, no-load, overcurrent, overcharge, overheating, short-circuit, charging time control, and reverse polarity protection, creating a robust safety barrier that effectively safeguards both the charger itself and the connected battery; it resumes work automatically when the fault is repaired. 【Smart Charging Technology】: The CPU of our charger will monitor charging process to avoid overcharging and auto shut down when fully charged to protect your battery health and extend battery life. 【OV Charging Wake Up Mode】: Our lithium battery charger can reset and repair the battery after BMS cut-off protection. When you forget to charge the battery regularly for a long time, our charger can wake up your low-voltage 12V LifePO4 batteries. 【Fast Heat Dissipation Design】: Cooling fan runs continuously while charging, with overheating protection that shuts down the charger when ambient temperature exceeds 65℃(149℉). 【2 Connection Methods】: M8 terminal connector can be remained on the battery without frequent removal. Alligator battery clips can be directly clamped on the battery with protruding pole lugs. 【Wide Application】: Widely used in RV, solar system, cars, lighting equipment, trolling motor, electric yacht, etc. 【3-Color LED indicator】: The status indicator uses a combination of colors and flashing patterns to represent different charging stages. 1. Red Light Flashing: Indicates Normal Charging, corresponding to a battery level from 0% to 80%. 2. Yellow Light Flashing: Signifies Small Current Charging (trickle charge), which occurs between 80% and 99% capacity. 3. Green Light Flashing: Means the battery is Almost Full (approximately 100%). 4. Green Light Solid (On): Shows the battery is fully charged (100%) and the charger is in Standby mode. This light also signifies the Over-Voltage (OV) Charging Wake-up Mode.
