Victron -Phoenix Smart IP43 Charger 24/16 (1 + 1) Battery Charger

Bluetooth Smart enabled
Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available.Three full power outputs for charging 3 batteries
Each output can provide the full rated output current. But the total of 3 outputs combined can never exceed the current rating of the charger.

Customizable 5-step charging algorithm: mass absorption-repair-floating storage-storage
The Phoenix Smart Charger features our well-known "adaptive" battery management system that can be pre-configured to suit different types of batteries. The "customizable" function will automatically optimize the charging process in relation to how the battery is used.

BatterySafe function. Prevention of damage due to excessive gas:  
If, in order to quickly charge a battery, a high charging current is selected in combination with a high suction voltage, the charger will prevent damage due to excessive gas by automatically limiting the voltage rise rate once the gas voltage has been reached.

It also charges Li-ion (LiFePO4) O batteries
charger on-off control can be implemented by connecting a relay or an open-collector optocoupler output from a Li-ion BMS to the remote on-off port.
Alternatively, complete control of voltage and current can be achieved with Bluetooth.

Fully programmable algorithm
charging The charging algorithm can be programmed with the help of Bluetooth or the VE.Direct interface. Three pre-programmed algorithms can be selected with the mode button (see specifications).

On-off
remote control The on / off remote control consists of two terminals: Remote control H and Remote control L.
A remote on / off switch or relay contact can be connected between H and L.
