1. Quick user guide
The Blue Smart IP67 chargers will charge and maintain lead-acid
and Li-ion batteries, and supply users connected to the battery.
In addition, the models with suffix (1+Si) feature a second current
limited output which is always powered as long as 230VAC is
present on the input. This output can for example be used to
prevent starting of a vehicle before unplugging the battery
charger (start interrupt function).
Blue Smart version
Set-up, monitor and update the charger (add new features when
they become available) using Apple and Android smartphones,
tablets or other devices with the VictronConnect App.
VictronConnect is available to users of Windows PCs, macOS X,
iOS and Android phones, as well as tablets.

VictronConnect: Blue Smart IP67 charger pages
When the Blue Smart charger is powered-up it will be discoverable
using the VictronConnect app on your device.
The 'home' page shows information about the battery voltage, charge
current, and where your battery is in the charging-cycle.
To access the Settings button click on the cog icon at the top right
of the screen. From here you can choose a preset charge algorithm,
you can select the charge current; and you can choose to employ the
charge algorithm for a Li-ion battery when that is appropriate.

2. ‘Must know’ features and facts
2.1 Ultra high efficiency “green” battery charger
With up to 95% efficiency, these chargers generate up to four
times less heat when compared to the industry standard.
And once the battery is fully charged, power consumption
reduces to 0.5 Watt, some five to ten times better than the
industry standard.
2.2 Durable, safe and silent
- Low thermal stress on the electronic components.
- Protection against ingress of dust, water and chemicals.
- Protection against overheating: the output current will
reduce as temperature increases up to 60°C, but the
charger will not fail.
- The chargers are totally silent: no cooling fan or any other
moving parts.
2.3 Reverse polarity protected
In case of wrong polarity connection, the external ATO blade fuse
will blow. Check the polarity of the cable and check the correct
value before replacing the fuse.
2.4 Recovery function for fully discharged batteries
Most reverse polarity protected chargers will not recognize, and
therefore not recharge a battery which has been discharged to
zero or nearly zero Volts. The Blue Smart IP67 Charger however
will attempt to recharge a fully discharged battery with low current
and resume normal charging once sufficient voltage has
developed across the battery terminals.
2.5 Temperature compensated charging
The optimal charge voltage of a lead-acid battery varies inversely
with temperature. The Blue Smart IP67 Charger measures
ambient temperature during the test phase and compensates for
temperature during the charge process. The temperature is
measured again when the charger is in low current mode during
float or storage. Special settings for a cold or hot environment are
therefore not needed.

2.6 Adaptive Battery Management
Lead-acid batteries should be charged in three stages, which are
[1] bulk or constant-current charge,
[2] absorption or topping
charge and [3] float charge.
Several hours of absorption charge are needed to fully charge the
battery and prevent early failure to sulfation¹.
The relatively high voltage during absorption does however
accelerate aging due to grid corrosion on the positive plates.
Adaptive Battery Management limits corrosion by reducing
absorption time when possible, that is: when charging a battery
that is already (nearly) fully charged.
2.7 Storage mode: less corrosion of the positive plates
Even the lower float charge voltage that follows the absorption
period will cause grid corrosion. It is therefore essential to reduce
the charge voltage even further when the battery remains
connected to the charger during more than 48 hours.
2.8 Reconditioning
A lead-acid battery that has been insufficiently charged or has
been left discharged during days or weeks will deteriorate due to
sulfation¹. If caught in time, sulfation can sometimes be partially
reversed by charging the battery with low current up to a higher
voltage.
Remarks:
a) Reconditioning should be applied only occasionally to flat plate VRLA
(gel and AGM) batteries because the resulting gassing will dry out the
electrolyte.
b) Cylindrical cell VRLA batteries build more internal pressure before
gassing and will therefore lose less water when subjected to
reconditioning. Some manufacturers of cylindrical cell batteries
therefore recommend the reconditioning setting in case of cyclic
application.
c) Reconditioning can be applied to flooded batteries to “equalise” the
cells and to prevent acid stratification.
d) Some battery charger manufactures recommend pulse charging to
reverse sulfation. However, most battery experts agree that there is
no conclusive proof that pulse charging works any better than
constant voltage charging. This is confirmed by our own tests.

2.9 Lithium-ion (LiFePO₄) batteries
Li-ion batteries do not suffer from sulfation.
But Li-ion batteries are very sensitive to under voltage or over
voltage².
Li-ion batteries therefore often have integrated cell balancing and
under voltage protection (UVP) circuitry.
Some reverse polarity protected chargers will not recognize a
battery when the UVP has tripped.
The Blue Smart Charger will however automatically reset the
UVP and start charging.
Important note:
NEVER attempt to charge a Li-ion battery when its
temperature is below 0°C.
2.10 Low current mode
Some lead acid batteries can overheat if charged with a current
exceeding 0.3C (C is the capacity in Ah. A 12Ah battery for
example should not be charged with a current exceeding
0.3 x 12 = 4A). The low current mode (charge current limited to
4A or less, see technical specifications) should therefore be used
to charge low capacity lead-acid batteries.

3. Charge algorithms
3.1 Smart charge algorithm with optional reconditioning for
lead-acid batteries
Charge voltages at room temperature:
For 24V chargers: multiply all voltage values by 2.
NORMAL (14.4V): recommended for flooded flat plate lead
antimony batteries (starter batteries), flat plate gel and AGM
batteries.
HIGH (14.7V): recommended for flooded lead calcium batteries,
Optima spiral cell batteries and Odyssey batteries.
State of the art microprocessor controlled charge algorithm
Adaptive 5-stage charge characteristic: bulk – absorption –
recondition - float – storage
The Blue Smart IP67 charger features a microprocessor
controlled ‘adaptive’ battery management system. The ‘adaptive’
feature will automatically optimise the process relative to the way
the battery is being used.
1. BULK
Charges the battery with maximum current until absorption
voltage is reached. The battery will then be about 80%
charged and is ready for use.
2. ABS - Absorption
Charges the battery at constant voltage and with
decreasing current until it is fully charged.
See table above for absorption voltage at room
temperature.
Adaptive battery management:
The absorption time is short (minimum 30 minutes) if the
