• MCU control, ultra-low power consumption when standby.

• The charging principle adopts a three-stage charging algorithm, which performs a balanced charging of the battery once a week, effectively preventing the battery from being unbalanced and vulcanized, and improving the service life of the battery.

• Power MOSFET as an electronic switch without any mechanical switch, no protection action delay

• Green and Red LED light indication for charge and discharge; discharge light control + timing, pure light control, manual adjustment on the ALWAYS ON mode
