7. All features and settings

This chapter explains all battery monitor settings. In addition to this we also have a video available explaining these settings and
how the interact with each other to achieve accurate battery monitoring for both lead-acid and lithium batteries.

7.1. Battery settings

These settings can be used to fine-tune the SmartShunt. Please be careful when you change these settings as a change will
have an effect on the SmartShunt state of charge calculations.

7.1.1. Battery capacity

This parameter is used to tell the battery monitor how big the battery is. This setting should already have been done during the
initial installation.
The setting is the battery capacity in Amp hours (Ah).
For more information on Battery capacity and Peukert exponent see chapter
Default setting Range
200 Ah 1 - 9999 Ah

7.1.2. Charged voltage

The battery voltage must be above this voltage level to consider the battery as fully charged. As soon as the battery monitor
detects that the voltage of the battery has reached the "charged voltage" and the current has dropped below the "tail current" for a
certain amount of time, the battery monitor will set the state of charge to 100%.
Default setting Range
0 V 0V - 95V
The "charged voltage" parameter should be set to 0.2V or 0.3V below the float voltage of the charger.
Table 2. Recommended settings for lead acid batteries:
Nominal battery voltage Charged voltage setting
12V 13.2V
24V 26.4V
36V 39.6V
48V 52.8V

7.1.3. Discharge floor

The "Discharge floor" parameter is used in the time remaining calculation. The battery monitor calculates the time it takes until the
set "discharge floor" has been reached. It is also used to set the state of charge alarm defaults.
For lead-acid batteries set this to 50% and for lithium set it lower.
Default setting Range
50% 0 - 99%
