Victron Energy Blue Smart IP67 punjač 24/12 (1)

This model, the Blue Smart IP67 Charger 24/12 (1), is a 24 V battery charger that delivers a maximum charging current of 12 A in normal mode.

The IP67 rating means the charger is fully encapsulated, making it waterproof, shock-resistant, and protected against ignition. Its die-cast aluminum housing and resin-impregnated electronic components ensure high durability in demanding environments such as boat bilges.

The charger includes Bluetooth Smart functionality, allowing you to control and monitor it wirelessly. You can access voltage settings, current settings, and software updates via the VictronConnect app from your smartphone or tablet (compatible with Apple and Android).

This charger stands out with a high energy efficiency of 96 %. This performance minimizes heat dissipation, meaning it wastes three to four times less heat than standard chargers.

The charger uses a 5-stage adaptive charging algorithm:

Bulk (bulk charge)Absorption (absorption charge)ReconditioningFloat (float maintenance)StorageThis algorithm is controlled by a microprocessor to optimize the charging process based on battery usage and extend its lifespan.

Yes, the Blue Smart IP67 charger is completely silent. It has no cooling fan or other moving parts, which reduces thermal stress on the electronic components.

The charger dimensions are 99 x 219 x 65 mm (height x width x depth). Its weight is 2.4 kg.

Yes, this charger can also be used as a power supply, providing additional flexibility for various applications.

The charger is protected against overheating. If the ambient temperature exceeds 40 °C, it automatically reduces its output current. It can operate without failure up to 60 °C, with a 3 % current reduction per degree above 40 °C.

The charger is equipped with two LEDs for status indication:

The yellow LED indicates the charge state: fast blinking for bulk charging, slow blinking for absorption, solid for float charging, and off for storage mode. The green LED indicates that the device is powered on.

Once the battery is fully charged, the charger's power consumption drops to less than 1 Watt, which is five to ten times better than the industry standard.

Storage mode activates if the battery has not undergone discharge for 24 hours. In this mode, the float voltage is reduced to 26.4 V (for a 24 V battery) to minimize gassing and corrosion of the positive plates. Once per week, the voltage is increased to the absorption level to 'equalize' the battery, preventing electrolyte stratification and sulfation.

Yes, the charger is protected against reverse polarity. In case of incorrect connection, the external ATO fuse will blow. It is important to check polarity and the correct fuse rating before replacement.

This charger is compatible with lead-acid batteries (including flooded, gel, and AGM types) and Li-ion batteries. For Li-ion batteries, it uses a simple three-stage charging algorithm: bulk – absorption – float.

Yes, the Blue Smart IP67 charger has a recovery function for fully discharged batteries. It can initiate charging even if the battery has been discharged to zero volts and will reconnect to Li-ion batteries with internal disconnect function.

Yes, the charger includes a temperature-compensated charging function. It measures ambient temperature during the test phase and compensates for temperature during the charging process to optimize the charging voltage for lead-acid batteries. No special settings for cold or hot environments are required.

The charger operates on an input voltage range of 180 to 265 VAC with a frequency of 45 to 65 Hz.

For Li-ion batteries, the charging voltages are as follows:

Absorption voltage: 28.4 VFloat voltage (maintenance): 27.0 VStorage voltage: 27.0 V

The charger must be installed in a well-ventilated area, close to the battery. However, it should not be placed directly above the battery due to the potential corrosive gases emitted by it.

To connect the charger:

Connect the ring terminals to the battery: the black cable (negative) to the battery’s negative terminal (–), and the red cable (positive) to the battery’s positive terminal (+). Plug the AC power cable (fitted with a CEE 7/7 plug) into a wall outlet. The charging cycle will then start automatically.
