※LIFEPO4 BATTERY CHARGER With Plug Specially designed for charging and maintaining 12V (12.8V) LiFePO4 lithium ion batteries. Input Voltage: 100-220V AC | Output Voltage: 14.6V | Charging Current: 40A | Recommended for LiFePO4 batteries of 20 Amp Hours and above. The superior cables and alligator clips ensures effortless electrical connection between the charger and battery terminals. ※BATTERY-FRIENDLY - With built-in micro-controller, our lifepo4 charger is intelligently programmed to implement the special 2-stage constant current/constant voltage (CC/CV) charge algorithm regardless if the battery has BMS or not, which can boost charging efficiency, get the best out of your battery and protect its delicate structure for longer lifespan. ※SAFE&RELIABLE - The durable aluminum alloy case and built-in cooling fan ensures efficient heat dissipation. It will automatically shutdown when battery is fully charged. Careful utilization of multiple protections against short circuit, over-current, over-voltage, low-voltage, over-heating and reverse connection ※SUPERIOR DESIGN - Heavy duty aluminum alloy case contributes to resist harsh conditions and thickened cables ensure long last durability. The LED light is solid red when charging and turns solid green when fully charged. What’s more, the package comes with a backup fuse for replacement. ※Durable and Cooling Fast - The durable aluminum alloy shell and cooling fan allow the charger's exterior to function as a heat sink with over-heating protection. In the MTBF test, it makes more than 30,000 POH(power on hours). Note: 1. NEVER turn on before connect lithium battery positive and negative correctly! 2. NEVER short circuit between this charger's positive and negative! 3. How Choose The Current: If your battery capacity is 135AH will suggest you use 20a or 30A charger and the charging time will 5~7 hours If you choose 10A will need more than 10 hours ※With built-in micro-controller, our lifepo4 charger is intelligently programmed to implement the special 2-stage constant current/constant voltage (CC/CV) charge algorithm regardless if the battery has BMS or not, which can boost charging efficiency, get the best out of your battery and protect its delicate structure for longer lifespan ※Lithium chargers are based on a CV/CC (constant voltage/constant current) charge algorithm. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level. The current then reduces as the battery becomes fully charged. This system allows fast charging without the risk of over-charging and is suitable for Lithium Iron and other battery types. ※Ultimately, using a battery charger with a specific Lithium charge algorithm is the best option for maximum performance and lifespan of any lithium battery. Using any other charger may cause damage to the Lithium battery.
