Description:

High performance booster MPPT charging ways.

The system uses solar panel power supply, reduce the power consumption of the battery.

The LED status indicator.

4 LED digital tube current-time display charging current, battery voltage, and solar energy input voltage, running status be clear at a glance.

Complete over-charge, anti-recoil, anti-reverse, and short circuit protection.

Built-in child lock safety switch,After locked, the external battery parameters can not be set to prevent misuse caused by charging button error, child lock does not affect the digital display and voltage query.

Optional battery voltage for 24V/36V/48V/60V/72V ,or setting the battery charging voltageas your will(User setting by the inner switch button).
