Features: Faster Charging: This charger has a faster-charging speed because of the 400W power, which can reduce your waiting time. Safe to Use: The high-quality charger provides short-circuit protection. It can stop charging immediately if there is an abnormality, such as a short circuit in the charging, which is safer to use. Protecting the Battery: The five-stage pulse repair charging will hold continuous restoration during the charging so that the battery is not damaged. Battery Dual Mode: It can adapt to two kinds of batteries. The left can charge lithium batteries, and the right can charge ordinary batteries. Automatic Recognition of Winter Patterns: Even in cold places, you don't have to worry about battery charging because it automatically recognizes winter mode, so it is also suitable for cold areas. Automatic Voltage Recognition: It will automatically identify the 12V or 24V battery to adjust the current according to the different voltages of the battery to achieve accurate and effective charging. Good Heat Dissipation: The charger with dual fans and a thermostatic cooling function has a good heat dissipation effect, extending the life of the charger. Meeting Your Various Needs: The charger with various working modes, such as pre-charge, constant current, constant voltage, and trickle current is fully functional and can meet your various needs. Details: LCD Display: The charger with a display can accurately show voltage, current, and battery power, allowing you to read data and charge in time. Battery Clamps: Two wrap-around high bite force battery clamps make charging safer and more secure. Automatic/Manual Charging Buttons: There are two automatic/manual charging buttons on the panel. You just need to press this button to achieve one-touch charging, which is so easy and convenient. Current Regulation Knob: You can freely regulate the current according to different batteries and the specific situation, which can meet your various needs. Handle: The charger is easy to carry because of a handle on top of the charger. It can be used to charge a motorcycle when you go out. Specification: Housing Material: Metal Voltage Range: 110V-250V Rated Power: 400W Working Temperature: -30 - + 50 Working Mode: Recharge - constant, Current-constant, Voltage-trickle The Actual Output Current (12V Battery): About 30A The Actual Output Current (24V Battery): About 15A How to Use 1. Examine and make sure the rated voltage of the battery is conforming to the output voltage of the charger. 2. Connect correctly the charger and the battery. 3. Examine and make sure the main supply voltage is conforming to the input voltage of the charger. 4. Connect the main supply and the battery, see if the indicator is on and the cooling fan is working when charging. 5. If the charger refuses to work, turn off the main supply immediately and check all the connecting cables between the main supply, the battery, and the charger. 6. If you have any problems, please feel free to contact us, we will reply and solve the problem for you as soon as possible. Notes: Please read the manual completely before installation and use. And pay particular attention to the safety instructions included. Strictly speaking, the charger can charge a 12.6V lithium battery no matter how the battery is combined to achieve a full voltage of 12.6V. However, the charger is not available for the lithium iron phosphate battery, the lithium iron battery, and the battery with an actual full charge voltage of 14.3V. Do not use under humidity or high temperature, or where there are flammables or explosives. Do not block the cooling hole, or use the charger while the cooling fan is stopped. Do prevent rain or water entry into the machine to avoid damages. Non-professional technicians are strictly prohibited to open the machine or change its purpose. Otherwise, severe injury may be caused. Please allow the slight color difference caused by the shooting light and 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
