7 Stage EBC Series 12/24V 10A-60A

The current is 10-60amp for 12V and 5-30amp for 24V. It is dual battery charger, which can charge 2pcs of batteries in parallel with same capacity at the same time. The LCD display shows battery voltage, output current, different charging status, overheat protection. The LED light indicates the battery type. The end user can select the display by pressing the buttons. With strong safety function, it has protection against reverse polarity, output short circuit, over current, over voltage, overload, overheat. It allows the charger to be left permanently connected to the battery for unattended automatic charging. 

This preliminary charging stage can improve battery condition and recover lost capacity from older batteries. It improves the charge delivered to the batteries, thereby increasing battery life and preventing premature battery failure.
The desulphation stage is able to break down sulphation that occurs in batteries which have been left flat for extended periods of time, returning them back to full charge.
To maintain an optimal internal temperature, the inbuilt fan is automatically enabled when a high temperature or charging current is detected.
The charger can provide a direct supply of power to a 12V load (e.g. 12V fridge) with no battery connected (e.g. during battery replacement).
It is the best portable battery charger you can try!
