Blue Smart IP67 Charger 12/25 (1+Si)

The Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) has an IP67 protection rating. This means it is fully waterproof, oilproof, and dirtproof, making it ideal for demanding environments. Its die-cast aluminum housing and electronics encapsulated in resin also provide excellent shock resistance.

The charger is equipped with Bluetooth Smart connectivity. You can use the VictronConnect app on your smartphone, tablet (Apple or Android) or PC to monitor voltage and current, adjust charge settings and perform software updates.

The Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) displays a very high efficiency of 95%. This means it minimizes heat dissipation and significantly reduces standby power consumption, which is only 0.5 W once the battery is fully charged.

For lead-acid batteries, the charger uses a 5-stage adaptive charging algorithm:

Bulk: Constant-current charge. Absorption: Constant-voltage charge to complete charging. Reconditioning: Optional phase to recover deeply discharged batteries. Float: Maintains the battery at a float voltage. Storage: Reduces float voltage to minimize aging when the battery is not in use. This algorithm optimizes battery lifespan.

Yes, the Blue Smart IP67 Charger 12/25 (1+Si) charger has a recovery function for fully discharged batteries. It can initiate charging even if the battery is at 0 volts. It can also reconnect to a fully discharged Li-ion battery with an internal disconnect function.

The charger is protected against overheating. If the internal temperature exceeds 40 °C, the output current is automatically reduced. The charger can operate safely up to 60 °C without failure, although current may be reduced to maintain stability.

The specific model (1+Si) is equipped with a second current-limited output of 0.5 A. The voltage of this output is at most one volt lower than that of the main output. It is primarily intended for a start-interrupt function, for example to prevent a vehicle from starting before the charger is disconnected.

The dimensions of the Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) charger are 99 mm (height) x 219 mm (width) x 65 mm (depth). Its weight is 2.4 kg.

The charger is equipped with two status LEDs:

The yellow LED indicates the charge state: fast blinking for bulk charging, slow blinking for absorption, solid for float, and off for storage mode. The green LED indicates that the charger is powered on. You can also retrieve detailed information via the VictronConnect app.

Yes, the Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) can be used as a power supply.

This charger is designed to charge and maintain lead-acid batteries (including AGM, GEL, and flooded types) and Li-ion (Lithium-ion) batteries.

The Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) is suitable for batteries with a capacity between 14 Ah and 225 Ah.

Charge voltages vary by battery type and mode:

Absorption voltage: 14.4 V (Normal), 14.7 V (High), 14.2 V (Li-ion). Float voltage: 13.8 V (Normal/High), 13.5 V (Li-ion). Storage voltage: 13.2 V (Normal/High), 13.5 V (Li-ion). These parameters can be adjusted via the VictronConnect app.

Yes, the charger is compatible with a nominal input voltage range of 220-240 VAC and a frequency of 50-60 Hz. The actual supported input voltage range is 180-265 VAC at 45-65 Hz.

Yes, it is important to note that a battery management system (BMS) may be required to charge a Li-ion battery safely and in accordance with the battery manufacturer's recommendations.

The charger must be installed in a well-ventilated area near the battery. However, due to potential corrosive gases emitted by some batteries, it must never be placed directly above the battery.

To connect the charger to the battery:

Connect the negative ring terminal (black cable) to the negative pole (–) of the battery. Connect the positive ring terminal (red cable) to the positive pole (+) of the battery. Once the DC connections are made, plug the AC power cable into a wall outlet. Always ensure correct polarity and never let the terminals touch.

When installing in a vehicle, route AC and DC cables to minimize the risk of damage from the hood, door, or moving engine components. Keep away from fan blades, belts, and pulleys. Always connect the charger’s positive terminal (red) to the battery’s positive terminal (not grounded), and the negative terminal (black) to the vehicle chassis or engine block, away from the battery. Always disconnect the AC cable before disconnecting the DC terminals.

Yes, the Victron Energy Blue Smart IP67 Charger 12/25 (1+Si) charger is completely silent. It has no cooling fan or other moving parts, which reduces thermal stress on the electronic components.

The charger comes with a 1.5-meter battery connection cable (black and red) and a 1.5-meter AC connection cable with a CEE 7/7 plug.
