Victron Blue Smart IP67 Battery Charger Bluetooth 12/25 (1+Si) CEE

Powerful Victron battery charger for 12V batteries with wireless monitoring function

Ready for Bluetooth Smart
The Blue Smart IP67 Battery Charger is the wireless solution for monitoring voltage and current, adjusting settings, and updating the charger when new features become available.
Simply download the app to your smartphone and connect to the battery charger via Bluetooth.

Fully encapsulated: waterproof, shockproof and flame retardant.
Water, oil or dirt cannot damage the Blue Smart IP67 Charger. The housing is made of cast aluminum and the electronics are encapsulated in resin.

High efficiency
With an efficiency of up to 94%, these chargers generate up to four times less heat compared to the industry standard. Furthermore, once the battery is fully charged, power consumption drops to less than 0.5 watts, which is about five to ten times better than the industry standard.

Auxiliary (1+Si)
Models with auxiliary (1+Si) have a second current-limited output that is always energized as long as 180 – 265V AC is available at the input. This output can be used, for example, to prevent a vehicle from starting before the battery charger has been disconnected (start interlock function).

Adaptive 6-stage charging algorithm: Test - Bulk - Absorption - Recondition - Float - Storage
The Blue Smart charger is characterized by its microprocessor-controlled, "adaptive" battery management. "Adaptive" means that the charging process is automatically adjusted to the type of battery use.

Storage Mode:
Less maintenance and aging when the battery is idle:
Storage mode is activated whenever no discharge has occurred within 24 hours. The float voltage is then reduced to 2.2V/cell (13.2V for a 12V battery) to minimize gassing and thus prevent corrosion of the positive plates. Once a week, the voltage is increased to the gassing level. This achieves a kind of equalization charge that prevents electrolyte stratification and sulfation - the two main reasons for premature battery failure.

Also charges Lithium-Ion (LiFePO4) batteries
LiFePO4 batteries are charged with a simple constant current phase - constant voltage phase - float voltage phase algorithm.

The NIGHT and LOW settings
When the device is in NIGHT or LOW mode, the output current is reduced to a maximum of 25% of the rated output and the charger operates absolutely silently. NIGHT mode ends automatically after 8 hours. LOW mode can be manually exited.

Overheat protection The output current is reduced if the temperature rises up to 50°C, but the Blue Smart charger will not fail.
