24V 30A volt Lithium battery charger, Fully-Automatic Smart Charger 85% Charging Efficiency for 200AH-300AH Lead-Acid, AGM, gel and LiFeP04 Batteries with LCD Screen & Temp. Control for Forklift/Golf Cart/Scrubbers/Sightseeing Car Instructions: 1. firstly connect the battery connector, then plug it into 110V or 220V power supply, turn on the power switch, and the machine will output current and voltage after self-checking for 3-4S.The digital display shows the current and voltage, the charging indicator light is on (red), and the charger may make a slight noise. When the battery is fully charged, the full indicator lights (green). 2. The digital display shows that the voltage and current are zero, and the fan stops after a delay of 60-120S. When the charger is over-temperature and over-current, the fault light is on (yellow), and the digital display shows zero voltage and current. 3. After charging is completed, turn off the power switch, then unplug the power supply plug, and finally unplug the battery connector. Fast charging Charging Charging time is faster than traditional models and the efficiency is twice that of traditional models; it charges a 100 amp hour battery in under an hour up to about 85 % Electricity.Reverse polarity, over voltage, under voltage, over temperature, short circuit protections. FULLY AUTOMATIC This lifepo4 charger is a fully-automatic smart fast charging equipment. The whole process only requires to plug in the power supply, turn on the power switch and it will automatically charge. No need manual supervision throughout the whole process, and the charging will automatically stop when it is full SMART TEMPETATURE CONTROL When the battery temperature is low, the fan can be automatically adjusted to a low speed to achieve a balance between quietness and cooling efficiency. When the battery temperature is normal, the fan will be turned to the running mode to complete the fast charging of the battery.if the battery is overheating,the machine will enter the power-off protection mode. Lightweight & Widely used This Smart Battery Charger is 3.1kg only and designed with a portable handle for carrying around. Suitable for 24V, 200AH-300AH lead-acid batteries vehicles, such forklift, golf cart, floor scrubber and etc. A great charger. Read more Precautions 1. Be sure to distinguish the "+" and "-" poles when using the charger machine, which is available for 24V, 200AH -300AH lead-acid batteries. 2. Ensure that all connections are made with the power cut off. The correct sequence is to first connect the battery connector, then connect into the 110V or 220V power plug, turn on the power switch, confirm that the ground wire is connected reliably and there is no looseness, and finally connect the power plug into the power supply. 3. Do not use the way of charging connection to start the engine, which is easy to burn out the meter and motor. Cautions (Environment) 1. The operation of the machine should be carried out in a relatively dry environment, and the air humidity should not exceed 90 % in general. 2.The ambient temperature should be between -10℃ and 40℃. Operating temperature: -10°C to 40°C Storage temperature: -40°C to 75°C Relative humidity: 5% to 95% 3. Avoid operating in strong sunlight or rain, and do not allow water or rain to seep into the machine. 4. Avoid working in dusty areas or environments containing corrosive gases. 5. Avoid operating in an environment with strong air flow.
