1. Quick start guide
a) Connect DC cables to the charger and then the battery or
batteries; ensure that there is a good electrical connection
and keep the terminals away from any surrounding objects
that could cause a short circuit.
b) Connect the AC power cable to a mains power outlet; the
BULK LED will be illuminated when the blue smart charger
is powered up.
c) Select the charge mode appropriate for the battery type;
briefly press the MODE button to cycle through the available
options, the LED beside the currently selected charge mode
will be illuminated.

EN NL FR DE ES SE IT
The charger will automatically store the selected charge
mode and recall it for future charge cycles (even after being
disconnected from power).
When recondition mode is selected, the RECONDITION LED
will be illuminated in addition to the selected charge mode
LED.
If required, activate night mode (disabled fan and reduced
charge current for 8h); depress and hold the MODE button for
3 seconds, when activated the NIGHT LED will be
illuminated. Night mode will automatically end after 8 hours or
depress and hold the MODE button for 3 seconds again to
end night mode earlier.
If required, activate low current mode (disabled fan and
reduced charge current); depress and hold the MODE button
for 6 seconds, when activated the NIGHT LED will blink.
Depress and hold the MODE button for 6 seconds again to
end low current mode.
d) When the ABS LED is illuminated the charger has moved into
absorption stage (bulk stage is complete); the battery will be
approximately 80% charged and may be returned into service
if required.
e) When the FLOAT LED is illuminated the charger has moved
into float stage (absorption stage is complete); the battery will
be fully (100%) charged and is ready to be returned into
service.
f) When the STORAGE LED is illuminated the charger has
moved into storage mode (float stage is concluded); to
maintain the battery at full charge, the battery can be left on
continuous charge for an extended duration.
g) Disconnect the AC power cable from the mains power outlet
at any time to stop charging.

2. Features
a) Bluetooth setup and monitoring (Using VictronConnect)
Easily setup, monitor or update the charger firmware using
the VictronConnect app and a Bluetooth enabled device
(such as a mobile phone or tablet).
b) Multi-stage charge algorithm
The multi-stage charge algorithm is specifically engineered to
optimise each recharge cycle and charge maintenance over
extended periods.
c) Adaptive absorption
Adaptive absorption monitors the battery’s response during
initial charging and intelligently determines the appropriate
absorption duration for each individual charge cycle.
This ensures that the battery is fully recharged regardless of
the discharge level or capacity and avoids excessive time at
the elevated absorption voltage (that can accelerate battery
aging).
d) Temperature compensation
Charge voltage is automatically compensated depending on
the ambient temperate; this ensures that the battery is
charged at the optimal charge voltage regardless of the
climate and avoids the need for manual settings adjustments.
Temperature compensation is not required and automatically
disabled when in LI-ION charge mode.
e) High efficiency
The blue smart charger range is up to ~95% efficient;
resulting in lower power usage, less heat generated and
cooler operation.

5
EN NL FR DE ES SE IT
f) Durable and safe
i. Engineered to provide years of trouble-free and
dependable operation in all usage conditions
ii. Protection against overheating: output current will be
reduced if the charger temperature increases to 50°C
iii. Integrated cooling fan to maintain low charger
temperature during highly demanding conditions and
avoid the need for current reduction
iv. Protection against short circuit: If a short circuit
condition is detected the charger will immediately shut
down
v. Protection against reverse polarity connection: If the
charger is incorrectly connected to a battery with
reverse polarity the user replaceable fuse will blow
g) Silent operation
Charger operation is totally silent whilst the cooling fan is off;
the cooling fan is only activated during demanding periods,
when it is necessary.
If the NIGHT or LOW mode is activated; the maximum output
current is reduced to 50% of nominal and the cooling fan will
always remain off.
h) Lithium Ion compatible
Compatible with Li-ion (LiFePO₄) batteries; when the
integrated LI-ION charge mode is selected the charge cycle
settings are altered to suit.
If the charger is connected to a battery where under voltage
protection (UVP) has tripped, the blue smart charger range
will automatically reset UVP and start charging; many other
chargers will not recognise a battery in this state.
Warning: Never charge a Li-ion battery when its
temperature is below 0°C.

6
i) Storage stage
An additional stage to extend battery life whilst the battery is
unused and on continuous charge.
j) Recondition stage
An optional stage that can partially recover/reverse lead acid
battery degradation due to sulfation; typically caused by
inadequate charging or if the battery is left in a deeply
discharged state.
k) Low current mode
An optional mode that limits the maximum charge current to a
significantly reduced level; recommended when charging
lower capacity batteries with a high current charger.
l) Recovery function
The blue smart charger range will attempt to recharge a
severely discharged battery (even down to 0V) with low
current and then resume normal charging once the battery
voltage has risen sufficiently - many other chargers will not
recognise a battery in this state.
m) Power supply mode
A specific mode to use the charger as a DC power supply; to
power equipment at a constant voltage with or without a
battery connected.

3. Operation
3.1 Multi-stage charge algorithm
The Victron blue smart charger range are intelligent multi-stage
battery chargers, specifically engineered to optimise each recharge
cycle and charge maintenance over extended periods.
The multi-stage charge algorithm includes the individual charge
stages described below:
1. Bulk
The battery is charged at maximum charge current until the
voltage increases to the configured absorption voltage.
The bulk stage duration is dependent on the battery’s level of
discharge, the battery capacity and the charge current.
Once the bulk stage is complete, the battery will be
approximately 80% charged and may be returned into service
if required.
2. Absorption
The battery is charged at the configured absorption voltage,
with the charge current slowly decreasing as the battery
approaches full charge.
The absorption stage duration is adaptive and intelligently
varied depending on the battery’s level of discharge – this is
determined from the duration of the bulk charge stage.
The absorption stage duration can vary between a minimum
of 30 minutes, up to a maximum limit of 8 hours (or as
configured) for a deeply discharged battery.

8
3. Recondition
The battery is charged at low current until the voltage
increases to the configured recondition voltage.
Recondition is an optional charge stage for lead acid batteries
and not recommended for regular/cyclic use - use only if
required, as unnecessary or overuse will reduce battery life
due to excessive gassing.
The higher charge voltage during recondition stage can
partially recover/reverse battery degradation due to sulfation,
typically caused by inadequate charging or if the battery is left
in a deeply discharged state for an extended period (if
performed in time).
The recondition stage may also be applied to flooded
batteries occasionally to equalise individual cell voltages and
prevent acid stratification.
During recondition stage the charge current is limited to 8% of
the nominal charge current, (for example - 1.2A for a 15A
charger) and the stage is terminated as soon as the battery
voltage increases to the configured recondition voltage or
after a maximum duration of 1 hour (or as configured).
4. Float
The battery voltage is maintained at the configured float
voltage to prevent discharge.
Once float stage is commenced the battery is fully charged
and ready for use.
The float stage duration is also adaptive and varied between
4 to 8 hours depending on the duration of the absorption
charge stage, at which point the charger determines the
battery to be in storage stage.

9
EN NL FR DE ES SE IT
5. Storage
The battery voltage is maintained at the configured storage
voltage, which is slightly reduced compared to the float
voltage to minimise gassing and extend battery life whilst the
battery is unused and on continuous charge.
6. Refresh
To refresh the battery and prevent slow self-discharge while
in storage stage over an extended period, a 1 hour absorption
charge will automatically occur every 7 days (or as
configured).

10
3.2 Temperature compensation
The Victron blue smart charger range will automatically
compensate the configured charge voltage based on ambient
temperature (unless disabled or in Li-ion mode).
The optimal charge voltage of a lead acid battery varies inversely
with battery temperature; automatic temperature-based charge
voltage compensation avoids the need for special charge voltage
settings in hot or cold environments.
During power up the charger will measure its internal temperature
and use that temperature as the reference for temperature
compensation, however the initial temperature measurement is
limited to 25°C as it’s unknown if the charger is still warm from
earlier operation.
Since the charger generates some heat during operation, the
internal temperature measurement is only used dynamically if the
internal temperature measurement is considered reliable; when the
charge current has decreased to a low/negligible level and
adequate time has elapsed for the charger’s temperature to
stabilise.
The configured charge voltage is related to a nominal temperature
of 25°C and linear temperature compensation occurs between the
limits of 6°C and 50°C based on the default temperature
compensation coefficient of 16.2mV/°C (for 24v chargers multiply
the coefficient by 2) or as configured.
The temperature compensation coefficient is specified in mV/°C
and applies to the entire battery/battery bank (not per battery cell).

3.3 Commencing a new charge cycle
A new charge cycle will commence when:
i. Bulk stage is complete and the current output increases
to the maximum charge current for four seconds (due to
a simultaneously connected load)
ii. If re-bulk current is configured; the current output
exceeds the re-bulk current in float or storage stage for
four seconds (due to a simultaneously connected load)
iii. The MODE button is pressed or a new charge mode is
selected
iv. VictronConnect is used to select a new charge mode or
change the function from ‘Power Supply’ to ‘Charger’
mode
v. The AC supply has been disconnected and
reconnected

3.4 Estimating charge time
A lead acid battery is at approximately 80% state of charge (SOC)
when the bulk charge stage is completed.
The bulk stage duration Tbulk can be calculated as Tbulk = Ah / I,
where I is the charge current (excluding any loads) and Ah is the
depleted battery capacity below 80% SOC.
An absorption period Tabs of up to 8 hours may be required to fully
recharge a deeply discharged battery.
For example, the charge time of a fully discharged 100Ah battery
when charged with a 10A charger to approximately 80% SOC is
Tbulk = 100/10 = 10 hours.
Including an absorption duration of Tabs = 8 hours,the total
estimated charge time would be Ttotal = Tbulk + Tabs = 10 + 8 = 18
hours.
A Li-ion battery is more than 95% charged at the end of the bulk
stage and reaches 100% charge after approximately 30 minutes of
absorption charge.

4. Setup
4.1 Using the MODE button
There are 3 easily selectable integrated charge modes that are
suitable for most common battery types, as well as an optional
recondition stage that can be included (except for Li-ion mode).
Any settings made are stored and will not be lost when the charger
is disconnected from mains power or the battery.
a) Charge voltage
By simply selecting the appropriate charge mode for the
battery type being charged, (refer to the battery
manufacturer’s recommendations) the voltage settings for
each charge stage will be altered according to the table
below:
Mode Absorption Float Storage Recondition
Normal
14.4V
13.8V
13.2V
16.2V
High
14.7V
13.8V
13.2V
16.5V
Li-ion
14.2V 13.5V 13.5V N/A
Note: For 24V chargers multiply all voltages by 2.
Charge voltage is also automatically compensated depending
on ambient temperature (except for Li-ion mode) - see
section 3.2 ‘Temperature compensation’ for more information.
The desired charge mode can be selected by briefly pressing
the MODE button to cycle through the charge modes – the
LED beside the active charge mode (NORMAL / HIGH / LI-
ION) will be illuminated.

b) Recondition mode
If enabled the recondition stage is included in the charge
cycle; use only if required as a corrective/maintenance action
- see section 3.1 / 3 ‘Recondition’ for more information.
If recondition mode is enabled the RECONDITION LED will
be illuminated and blink during recondition stage.
c) Night mode
If enabled the charge current is temporarily limited to half the
nominal charge current and the cooling fan will be disabled
for totally silent operation over the following 8h (overnight).
Once 8h have elapsed the charger will return to normal
operation, with full charge current available and cooling fan
operation re-enabled.
To enable night mode, depress and hold the MODE button for
3 seconds; the NIGHT LED will illuminate once activated.
To end night mode prior to the 8h duration elapsing, also
depress and hold the MODE button for 3 seconds. Night
mode will also be ended if the charger is disconnected from
mains power.
d) Low current mode
If enabled the charge current is continuously limited to a
significantly reduced level (varies per model - refer to
specifications) compared to the nominal charge current and
the cooling fan will be disabled for totally silent operation.
Low current mode is recommended when charging lower
capacity batteries with a high current charger, for example
some lead acid batteries can overheat if charged with a
current that exceeds 0.3C (more than 30% of the battery
capacity in Ah).

16
To enable low current mode, depress and hold the MODE
button for 6 seconds; the NIGHT LED will blink once
activated.
To disable low current mode, also depress and hold the
MODE button for 6 seconds.
