With boat owners in mind this adaptive 5-step charger can provide either 30A or 50A of charge to each of three battery banks. Or the charger 1+1 model provides 3A to the starter-battery, the rest to the ‘house’ bank. 24V models are available with 16A/25A charge. Bluetooth enabled, you can monitor the charger and set alarms straight from your phone. Adaptive, intelligent, dynamic charge features Its suitable for a range of battery types including Lithium LiFePO4 Batteries.

Bluetooth Smart
The wireless solution to set-up, monitor, control and update Smart IP43 Chargers.

Smart IP43 Charger (1+1): two outputs to charge 2 battery banksThe second output, limited to approximately 3 A and with a slightly lower output voltage, is intended
to top up a starter battery.

Smart IP43 Charger (3): three full current outputs to charge 3 battery banks
Each output can supply the full rated output current. But the total of the 3 outputs combined can never
exceed the current rating of the charger.

Automatic voltage compensation
The charger compensates for voltage drop over the DC cabling by slightly increasing output voltage
when the DC current increases. Please see the manual for details.

Adaptive 6-stage charge algorithm: bulk– absorption – recondition – float – storage – refresh
The Smart IP43 Charger features our well-known ‘adaptive’ battery management system that can be
preset to suit different types of batteries. The ‘adaptive’ feature will automatically optimise the charge
process relative to the way the battery is being used.

The right amount of charge: variable absorption time
When only shallow discharges occur (a yacht connected to shore power for example) the absorption
time is kept short in order to prevent overcharging of the battery. After a deep discharge the
absorption time is automatically increased to make sure that the battery will be fully charged.

Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high absorption
voltage has been chosen, the charger will prevent damage due to excessive gassing by automatically
limiting the rate of voltage increase once the gassing voltage has been reached (see the charge curve
between 14,4 V and 15,0 V in fig. 2).

Less maintenance and aging when the battery is not in use: the Storage Mode
The Storage Mode kicks in whenever the battery has not been subjected to discharge during 24 hours.
In the Storage Mode float voltage is reduced to 2,2 V/cell (13,2 V for a 12 V battery) to minimise gassing
and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to
‘equalize’ the battery. This feature prevents stratification of the electrolyte and sulphation, a major
cause of early battery failure.

Also charges Li-ion (LiFePO₄) batteries
Charger on-off control can be implemented by connecting a relay or open collector optocoupler
output from a Li-ion BMS to the remote on/off port. Alternatively full control of voltage and current can
be achieved with Bluetooth.

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

Optional external battery voltage and temperature sensing via Bluetooth
A Smart Battery Sense, SmartShunt or a BMV-712 Smart Battery Monitor can be used to communicate
battery voltage and temperature to one or more Smart IP43 Chargers via VE.Smart Networking.

Remote on/off
The remote on/off consists of two terminals: Remote H and Remote L. A remote on/off switch or relay
contact can be connected between H and L. Alternatively, terminal H can be pulled high, or terminal L
can be pulled low. See the manual for details.

VE.Direct interface
For a wired data connection to a GX device such as the Cerbo GX, PC or other devices. Also enables
Instant Readout functionality via VictronConnect remotely from VRM. Please see the VictronConnect
app.

Programmable relay
Can be programmed using the VE.Direct interface or a Bluetooth enabled device to trip on an alarm or
other events.
