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.  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.
