3 General information
LXNAV SMARTSHUNT is smart battery monitoring unit
compatible with NMEA2000 network standard. It
accurately measures DC voltages of up to three
batteries bounded in series and includes shunt for
current measurements. It estimates state of charge,
state of health and remaining time until empty
battery. Up to three temperatures can be measured.
It supports multiple types of batteries and can be
configured through any LXNAV Exxx device or via
webpage accessible over internal Wi-Fi hotspot.
Parameters set there are available on NMEA2000
network to any device such as LXNAV's E350, E500
etc. LXNAV SMARTSHUNT is available in four versions
with 100, 300, 500 and 1000A shunt. All of them are
25 mV. For proper installation read next chapters
carefully.

Two operation modes
The SmartSHUNT operates in 2 modes:
To consume as less energy as possible, the
SmartSHUNT goes in ''Low power mode'' when the
following conditions are met:
The SmartSHUNT wakes up periodically (8s) from low
power mode to check the conditions between LOW
POWER MODE / NORMAL POWER MODE operation.
In this mode, the shunt is measuring if the above
conditions (low power mode) are still met. If so, the
device continues to run in Low power mode otherwise
it switches to normal operation.
operation mode by pressing the button on the unit for
8 seconds (for the whole sleep period).
It will stay in normal operation for 10 minutes. If after
10 minutes conditions to enter low power mode are
met, shunt will re-enter in low power mode.
N2K connector
Every 2 hours, the SmartSHUNT goes to normal
operation for 2 minutes even when all of the above
conditions are met in order to recalculate the
algorithm every once in a while.
