Specification Amperage : 2 amps Brand : Redodo BulletPoint1 : 【Fast Charging Speed】The single-channel voltage is up to 14.6V, with a maximum current of 20A. it can charge a 12V 100Ah LiFePO4 battery to 50% in 2.5 hours, 2 times faster than an ordinary 10A battery charger. BulletPoint2 : 【International Certification】Capable of charging LiFePO4 battery from 0V, and can reactivate the dead LiFePO4 battery.With CE & RoHS Certification: Full automatic transition of CC, CV, and Cut off.Aluminum Case, Two LED indicators, Safety and dependable. BulletPoint3 : 【Safe Charging】Our 14.6V 20A chargers equip with reverse polarity protection, output short circuit protection, output overvoltage protection, and battery isolation protection to prevent instability factors during the charging process. BulletPoint4 : 【Designed for Lifepo4 Battery】Redodo 14.6V 20A LiFePO4 is uniquely designed for 12V(12.8V) LiFePO4 batteries, implementing the special 2-stage constant current/constant voltage (CC/CV) charge algorithm. BulletPoint5 : 【Great Service】 If there is any question, we are always by your side. We are willing to provide professional technical support and customer service, including telephone support or online service, and promise to provide fast feedback within 24 hours BulletPoint6 : ✔【Special instructions for the 60A charger】: first plug the charger into the power supply-----look at the voltage---adjust the voltage-----then connect the load-----and then adjust the current. Step1: Do not connect the battery to the charger, turn on the power first, adjust the voltage knob to adjust the voltage, refer to the voltage display at the top of the display, (4S lifepo4 battery 3.65 v*4=14.6V, 3S lithium battery 4.2v *3=12.6V) , adjust to the voltage you need. BulletPoint7 : ✔【Step2】: Adjust the current to the minimum. After connecting the battery, adjust the current from small to large to the current you need. (It is not allowed to adjust the voltage knob again during the charging process, otherwise there will be overcharge or undercharge, which may burn the host at your own risk.) If the current on the display becomes zero, it means it is fully charged. BulletPoint8 : ✔【Charging】: During the charging process, the voltage of the display screen will drop, which is a normal phenomenon. Do not adjust the voltage of the charger while charging. In order to charge the battery with constant voltage, it is normal for the voltage of the charger itself to fluctuate. Adjust the voltage and current for the first time. No further adjustment is required later. If you do not understand, please consult customer service!

The charger has a voltage of 220V, and the maximum recommended current is 90%, for example, 60A. It is most suitable to adjust it to about 54A. The maximum recommended voltage and current of 110V is 80%, and the maximum recommended voltage and current of 100V is 70%.
