Victron Blue Smart IP65 Charger | IUoU Battery Charger 12V / 4A-25A / 230V | with DC Cable Set and Bluetooth

Ultra-high efficient green battery charger
With an efficiency of up to 94%, these chargers generate up to four times less heat compared to the industry standard. After 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.

Bluetooth Smart with the Victron Connect App
Set up, monitor, and configure the Blue Smart IP65 Charger via your smartphone.
Using the VictronConnect App, you can view the status of your charger and battery and even control the functions of your charger. By default, voltage and current are shown on the screen.

Durable, safe, and silent

• Low thermal stress on electronic components
• Protected against ingress of dust, water, and chemicals.
• Overheat protection: The output current is reduced if the temperature rises to 60 °C, but the charger will not fail.
• High performance in extreme cold: down to -30°C
• The chargers are completely silent: no fan or other moving parts.

Reverse polarity protection
After the battery is connected, the charger immediately determines the voltage and polarity. If the battery has been connected incorrectly, all status LEDs will flash. No sparking will occur.

Recovery function for deeply discharged batteries
Most reverse-polarity protected chargers do not recognize a battery that has been discharged to zero or almost zero volts
and therefore do not charge it. However, the Blue Power charger will attempt to charge a fully discharged battery with a low current. After sufficient voltage has been generated at the battery terminals, the device will begin the normal charging process.

Charging process with temperature compensation
The optimal charging voltage of a lead-acid battery varies inversely with temperature. The Blue Power IP65 charger measures the ambient temperature during the testing phase and performs temperature compensation during the charging process. The temperature is measured again when the charger is in low-current mode, float charge phase, or storage mode. Therefore, no special settings are required for cold or hot environments.

Adaptive Battery Management
Lead-acid batteries should be charged in three stages. These are: [1] 'bulk' or constant current phase, [2] 'absorption' or
constant voltage phase, and [3] 'float' or maintenance charge phase. The constant voltage phase must last several hours to fully charge the battery and prevent premature failure due to sulfation¹. However, the relatively high voltage during the constant voltage phase accelerates the aging process due to grid corrosion on the positive plates.
Adaptive Battery Management reduces corrosion by shortening the constant voltage phase when possible, which is the case when a battery that is already (almost) full is being charged.

Storage mode: less corrosion on the positive plates
Even the lower voltage of the float charge phase, which follows the constant voltage phase, leads to grid corrosion. Therefore, it is of utmost importance to further reduce the charging voltage if the battery remains connected to the charger for more than 48 hours and no battery usage occurs.

Reconditioning
A lead-acid battery that has not been adequately charged or that has been left in a discharged state for days or even weeks
loses capacity due to sulfation¹. If reconditioning occurs in time, this damage can be partially reversed by charging the battery first with a low current and then with a higher current.

Notes:
a) However, this reconditioning procedure should only be performed occasionally on grid-plate VRLA (Gel and AGM) batteries, as the resulting gassing will dry out the electrolyte.
b) VRLA tubular batteries build up more internal pressure before gassing occurs. Therefore, they lose less water when reconditioning is performed on them. Therefore, some manufacturers of tubular batteries recommend the reconditioning function for periodic use.
c) The reconditioning function can be used on liquid electrolyte batteries to equalize the cells and prevent acid stratification.
d) Some manufacturers of battery chargers recommend pulse charging to reverse sulfation. However, most battery experts agree that there is no clear evidence that pulse charging works better than constant voltage charging. Our own tests have also confirmed this.

Lithium iron (LiFePO₄) batteries
Lithium iron batteries do not experience sulfation. However, lithium iron batteries are very sensitive to excessively
high or low voltages. For this reason, lithium-ion batteries often have integrated cell balancing and undervoltage protection (UVP protection) circuitry. Some reverse-polarity protected chargers do not recognize a battery if the UVP has been triggered. However, the Blue Power charger automatically resets the UVP and begins the charging process.
Note: NEVER attempt to charge a lithium-ion battery if its temperature is below 0°C.

Low Current Mode
Some lead-acid batteries can overheat if charged with a current exceeding 0.3C (C is the capacity in Ah. For example, a 12 Ah battery should not be charged with a current exceeding 0.3 x 12 = 4 A). For this reason, Low Current Mode (charging current is limited, see also Technical Data) should be used to charge low capacity lead-acid batteries.
