Blue Smart IP65s Charger 12/4

The Victron Energy Blue Smart IP65s 12/4 charger is a professional battery charger designed to optimize battery lifespan and performance for 12V batteries. It is ideal for applications requiring precise and reliable charging, particularly for batteries between 20 and 50 Ah.

The IP65s protection rating means the charger is resistant to water, dust, and chemicals. This makes it particularly suitable for demanding environments such as marine settings or workshops.

This charger uses a 7-stage adaptive charging algorithm. This algorithm ensures optimized charging for lead-acid and LiFePO₄ batteries, thereby extending their lifespan.

Yes, the Blue Smart IP65s 12/4 charger can recover and recharge fully discharged batteries, even those that have dropped to 0 volts. It will attempt to recharge the battery with a low current and resume normal charging once sufficient voltage has been established.

Yes, Blue Smart IP65 chargers are completely silent. They have no cooling fan or any other moving parts, which reduces thermal stress on the electronic components.

The Blue Smart IP65s 12/4 charger delivers up to 94 % efficiency. This means it generates up to four times less heat than standard industry chargers, contributing to its durability.

The standby power consumption of the charger is only 0.5 Watt. This is five to ten times less than the industry average, making it a very energy-efficient device.

This charger is compatible with 12V lead-acid batteries (including AGM and Gel batteries) and LiFePO₄ (lithium-ion) batteries.

The Blue Smart IP65s 12/4 charger is recommended for batteries with a capacity ranging from 20 Ah to 50 Ah.

To connect the charger, follow these steps:

Connect the POSITIVE clamp (RED) of the charger to the POSITIVE terminal (POS, P, +) of the battery. Connect the NEGATIVE clamp (BLACK) of the charger to the NEGATIVE terminal (NEG, N, –) of the battery.

Once the clamps are connected, plug the AC power cable into the wall outlet.

Always unplug the AC cord from the wall outlet before connecting or disconnecting the DC clamps.

The charger is protected against reverse polarity. If the battery is connected incorrectly, all status LEDs will flash and no spark will occur, protecting both the charger and the battery.

The Blue Smart IP65s charger measures ambient temperature during the test phase and adjusts the charging voltage based on this temperature. The optimal charging voltage for a lead-acid battery varies inversely with temperature, eliminating the need for manual adjustments in cold or hot environments.

Storage mode is activated when the battery remains connected to the charger for more than 48 hours. It further reduces the charging voltage to minimize corrosion of the battery's positive plates, thereby extending its lifespan.

The reconditioning function is useful for lead-acid batteries that have been insufficiently charged or left discharged for days or weeks, which can lead to sulfation. If detected early, sulfation can sometimes be partially reversed by charging the battery with a low current at a higher voltage.

The VictronConnect app, available for iOS and Android smartphones and tablets, allows you to configure, monitor, and update your Blue Smart IP65s charger via Bluetooth Smart. You can view the charger and battery status, as well as remotely control the charger functions.

Place the charger as far away from the battery as possible, within the limits of the DC cables. Never place the charger directly above a charging battery, as battery gases could corrode and damage the charger. Ensure the area around the battery is well ventilated.

Yes, the Blue Smart IP65s 12/4 charger has an automatic power supply function, allowing it to maintain a constant voltage to power devices without a connected battery.

The Victron Energy Blue Smart IP65s 12/4 charger comes with a 5-year warranty.

Low-current mode allows charging smaller batteries with reduced current (e.g., 2A for this model). To activate it, hold the MODE button for 3 seconds. The MODE LED will flash to indicate low-current mode is active. It remains active until the MODE button is held again for 3 seconds.
