In order to better serve you and send the product correctly, you can not choose the US standard, UK standard, Australian standard plug when ordering, please contact the store customer service to help you order. 【Note 】 1 .The full load can be achieved only when the output voltage is within 220v - 240v. For chargers with an output current of 100A or more, when the input voltage is 110V-120V, the charging power can only reach 70%，About 70A. （Overloading can cause damage to the charger） Usage Notes: . Charging Procedure: During the charging process, it is strictly prohibited to adjust the voltage of the charger. Doing so will damage the charger! 1. First, adjust the charging voltage suitable for the battery. (lifepo4 of 3.65v x 4 = 14.6v, 3s li-ion: 4.2v x 3 = 12.6v),. Adjust to the voltage you needed. 2. Turn off the device, correctly connect the positive and negative terminals of the battery. 3. Turn on the charger and set the appropriate current.set the current to a minimum, after connecting the battery, set the current from small to large, adjust to the current you need. (in the charging process, do not adjust the voltage knob, otherwise there will be overload or lack of charge) 4. The charger has its own voltage and current adjustment function. When the charger is connected to the battery, the display on the charger shows the internal voltage of the battery. As the battery charges, the voltage gradually increases. The current size is determined by the internal battery charge. When the battery charge is less than 50%, the charger will output the maximum current you set. When the battery charge is greater than 70%, the charger will automatically adjust the output current and gradually decrease. When the charging is complete, the current is 0 and the charger enters a standby state. The charging current can be set. When the current is lower than the set value, the charger will automatically shut down. 5.If you show the voltage you set and the current reaches zero, it is already fully charged. Notes for charging the lead-acid battery: Lead acid batteries do not support high current charging. Use 1/10 of current load capacity. For example: lead-acid battery of 100a, to use 10a current charge! The time should be 8-10 hours, if the charge is too fast, the current will be too large to damage the battery. Lead-acid batteries can be charged to around 14.4 volts. The current will be too large to damage the battery. Lead-acid batteries can be charged to around 14.4 volts. Depending on the different brand of battery, the voltage varies slightly, see the instructions on the battery label. The following behaviors are strictly prohibited and will damage the charger: 1. The charger's outer shell is the negative pole voltage. It is strictly prohibited for the positive pole of the charger to touch the outer shell of the charger. 2. It is strictly prohibited for the outer shell of the charger to touch the positive or negative terminals of the battery. 3. It is strictly prohibited to use the charger in a sealed space, in a humid environment, or in the vicinity of flammable items. 4. It is strictly prohibited to charge a battery with a voltage of 15V or more.
