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.
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. Protection against short circuit: If a short circuit condition is detected all status-LEDs will start
blinking
iv. Protection against reverse polarity connection: If the charger is incorrectly connected with
reverse polarity all status-LEDs will start blinking
v. Protection against ingress of dust and water/liquid
g) Silent operation
Charger operation is totally silent: there is no cooling fan or moving parts.
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.
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.
