• 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.
