With boat owners in mind this adaptive 5-step charger can provide 25A of charge to each battery bank. It also provides 3A to the starter-battery, the rest to the ‘house’ bank. Bluetooth enabled, you can monitor the charger and set alarms straight from your phone. Adaptive, intelligent, dynamic charge features.

Bluetooth Smart built-in

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

Smart IP43 Charger (1+1): two outputs to charge 2 battery banks

The second output, limited to approximately 3 A and with a slightly lower output voltage, is intended to top up a starter battery.

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

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.

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.
