Victron Blue Smart Charger 20A

Bluetooth Smart

The wireless solution to monitor voltage and current, to change settings and to update the charger when new
features become available.

High efficiency

With up to 94 % 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.

Adaptive 6-stage charge algorithm: test - bulk – absorption - recondition – float – storage

The Blue Smart Charger features a microprocessor controlled ‘adaptive’ battery management. The adaptive
feature will automatically optimize the charging process relative to the way the battery is being used.

Fully programmable charge algorithm

Absorption, Float and Storage voltages as well as the Recondition setting and the temperature compensation
value can be programmed with the Bluetooth app.
After enabling the Expert mode, the app allows changing practically all parameters and time limits used by the
charge algorithm.

Storage Mode: less maintenance and aging when the battery is not in use

The storage mode kicks in whenever the battery has not been subjected to discharge for 24 hours. In the storage
mode float voltage is reduced to 2,2 V/cell (13,2 V for a 12 V battery) to minimize gassing and corrosion of the
positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize’ the battery. This feature
prevents stratification of the electrolyte and sulfation, which are major causes of early battery failure.

Also charges Li-ion batteries

Li-ion batteries are charged with a simple bulk – absorption – float algorithm.

Fully discharged battery recovery function

Will initiate charging even if the battery has been discharged to zero volts.
Will reconnect to a fully discharged Li-ion battery with internal disconnect function.

NIGHT and LOW setting

When in NIGHT or LOW mode, the output current is reduced to max. 50 % of the nominal output and the charger
will be totally noiseless. The NIGHT mode automatically ends after 8 hours. The LOW mode can be ended
manually.

Protected against overheating

Output current will reduce as temperature increases up to 50 °C, but the Blue Smart Charger will not fail.

Eleven LEDs for status indication

Charge algorithm: TEST / BULK / ABSORPTION / RECONDITION / FLOAT / STORAGE / READY.
MODE button to set: NORMAL (14,4 V) / HIGH (14,7 V) / RECONDITION / LI-ION.

Forty cycle history log

The history screen contains historical usage data over the charger’s lifetime and detailed statistics for the last 40
charge cycles.
