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.

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.

EN NL FR DE SE DA
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.

battery was (nearly) fully charged and increases to 8 hours
in case of a deeply discharged battery.
3. RECONDITION
Optional reconditioning for deeply discharged lead-acid
batteries.
Reconditioning is applicable to the charge algorithms
NORMAL and HIGH and can be selected with the App on
your smartphone.
When in RECONDITION mode the battery will be charged
with low current up to a higher voltage at the end of the
absorption phase.
During reconditioning the maximum current is equal to 8%
of the nominal current until the maximum voltage is
reached. Reconditioning is terminated after one hour or
when the maximum voltage is reached, whichever comes
first. See table.
Example:
For a 12/7 charger: the recondition current is
7 x 0.08 = 0.56A
4. FLOAT
Keeps the battery at constant voltage and fully charged.
5. STORAGE
Keeps the battery at reduced constant voltage to limit
gassing and corrosion of the positive plates.
Slow self-discharge is prevented by an automatic weekly
refresh of the battery with a short absorption charge.
3.2 Lithium-ion (LiFePO₄) batteries
When charging a Lithium-ion battery, the Blue Smart IP67
Charger uses a specific charging algorithm for Lithium-ion
batteries, to ensure optimum performance. Select LI-ION with
the app on your smart phone.
3.3 When a load is connected to the battery
A load can be applied to the battery while charging, as long as
the current draw is much lower than the rated output of the
battery charger.

10
Reconditioning is not possible when a load is connected to the
battery.
Remarks:
a) Disconnect all loads before attempting to recharge a very
weak or fully discharged lead-acid battery. Loads may be
reconnected once the bulk phase has started.
b) Disconnect all loads before attempting to recharge a Li-ion
battery when the under voltage protection (UVP) of the
Li˗ion battery has tripped. Loads may be reconnected once
the bulk phase has started.
3.4 Triggering a new charge cycle
A new charge cycle will start when:
a) The charger has reached float or storage, and, due to a
load, current increases up to maximum current during more
than four seconds.
b) The AC supply has been disconnected and reconnected.
3.5 Estimating charge time
A lead-acid battery is about 80% charged at the beginning of the
absorption period.
The time Tto 80% charged can be calculated as follows:
T = Ah / I
Where:
Iis the charge current (= charger output minus load current).
Ah is the amount of Ah to be charged.
A full absorption period of up to 8 hours is needed to charge the
battery to 100%.
Example:
Charge time to 80% of a fully discharged 100Ah battery when
charged with a 10A Blue Smart Charger: T = 100 / 10 = 10 hours
Charge time to 100%: 10 + 8 = 18 hours.
A Li-ion battery is more than 95% charged at the beginning of the
absorption period, and reaches 100% charge after approximately
30 minutes absorption charge.

EN NL FR DE SE DA
3.6 High internal resistance
When a battery reaches the end of its cycle- or float life, or when
it dies prematurely due to sulfation or corrosion, capacity will
dramatically drop and internal resistance will increase. The
charger will not recognise such a battery during the test phase (it
could as well be a nearly fully charged battery).
A very short bulk phase when charging a supposedly discharged
battery does however indicate that the battery has reached the
end of its useful life.
Remark: sulfation can sometimes be partially reversed by
repeated application of the RECONDITION MODE.
3.7 Can be used as a power supply
The charger will supply DC loads when no battery is connected.
