Features: Multifunctional design: Equipped with charging and discharging functions, it can be used to simultaneously charge and discharge 3S/4S lithium batteries, with 30Amp fuses protections (replaceable when the fuses burns out), and provides balanced charging and protections functions to ensure safe use of the battery. Efficient charging: supports fast and efficient charging process, provides stable charging current, shortens charging time, and improves work efficiency. XT60 plug interfaces: Adopting XT60 plug designing, it is convenient to connect with various matching devices, ensuring reliable power transmission, reducing contact impedances, and improving battery performances. Lithium battery balanced charging protections: Equipped with a built-in lithium battery balanced charging protections function, it can monitor and adjust the voltage of each individual battery in the battery pack in real time, cyclically display the voltage of a single cell and the total voltage, ensuring the balanced charging and service life of the battery. Expansion interfaces: Provides an expansion interfaces that can connect other devices, such as temperature sensors, to monitor and control the charging and discharging process of the battery.
