Description :

High performance booster MPPT charging ways .

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

The LED indicator .

4 LED digital tube current - time display charging current , battery voltage , and solar energy input voltage , running 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 ).
