Charging voltage: 14.6V2. Charging current: 10A3. Input voltage: 100v-240vNOTE: The red indicator light indicates that the charging is in progress, and the green indicator light indicates that the charging is completed. Interface Introduction Note: all interfaces can be charged and discharged!① Charging socket (GX16,3-pin airhead)This interface is used by the charger to charge the battery, Its overcurrent is less than 10A.② Waterproof plug (20A，LD20)Its generally used to connect low-power load equipment such as fish detector. Its overcurrent is less than 20A.③ Anderson plug (50A)Anderson plug (50a specification) is mainly used to connect low-power electric motor( below 600W). Its overcurrent is less than 50A④⑤ 8mm terminal (Discharge/charge interface)Its overcurrent is less than 150A.Suitable for connection with 8 mm diameter copper nose.⑥ USB3.0/PD It can charge electronic and digital products such as mobile phones and Notebook computer.⑦ DisplayIt can display voltage, power percentage and temperature.Please note: The percentage of electricity displayed on this display is inaccurate. When using it, you need to estimate the remaining electricity according to the voltage.1. The power of 12V LiFePO4 battery is concentrated between 12.2v-13.2v. When the voltage is lower than 12V, BMS will soon cut off the battery output.2. When charging, the indicator light of the charger changes from red to green to indicate full charge. Application Boat propeller battery, Camper/scooter, golf trolley/carts, power tools...Inverter, Solar and wind power system, RV, caravan...Back-up system and UPS... Torch LED light emergency light. Battery cell type Adopts large single high power LiFePO4 battery. The current output is more stable and stronger.LiFePO4 battery have higher safety, longer service life and a wider operating temperature range. Built-in BMS Our batteries are equipped with a BMS and an active equalizer.(Bluetooth BMS can be selected in the purchase option)Built in Bluetooth BMS (battery management system, functions)1. over charge protection. 2. over current protection. 3. over voltage protection4. discharge protection. 5. short circuit protection. 6. over power protection.7. temperature protection.About Bluetooth BMS features:By connecting to the BMS of the battery through this APP, we can check the working status of the battery (battery voltage, current, voltage of each battery cell) on the APP, and also control the discharge and charging of the battery on the APP.
