Temperature sensor can be connected

by Jens E.

Does what it should -) After a problem-free installation, the configuration was just as uneventful. Battery parameters set, NMEA2000 data set on the B&G Triton² and that's it! Now the shunt has to collect data first so that the whole thing can look good. It will look chic later on OpenCPN ;-)

Product details

LXNAV SmartSHUNT 300 A with NMEA2000 and WiFi Interface

Precise current/voltage and temperature measurement

The LXNAV SmartSHUNT measures battery voltage and current, as well as battery temperature data with the three sensors that are included in the box. The measured data is used to calculate the current state of charge and remaining battery life. The shunt is able to work with voltages of 12V, 24V, 32V, 36V or 48V.

The following battery types are supported:

Lead acid (LEAD ACID)
GEL
AGM
LiFePo Lithium

Not only can the measured data and current battery status be displayed via the integrated WiFi module, but also settings such as battery type, temperature units, and detailed shunt parameters such as Peukert exponent and temperature coefficients.

SmartSHUNT Features

WiFi configuration

All settings can be conveniently adjusted via WiFi using your smartphone.

Low power consumption

The LXNAV SmartSHUNT requires extremely little current to operate at 21 mA (via NMEA2000 at 12V).

Battery compatibility

Use the option to connect lead acid (LEAD ACID), GEL, AGM, and LiFePo lithium batteries.

High cost/benefit factor

Utilise the SmartSHUNT All-In-One device to output data via WiFi and NMEA2000 without the need of additional hardware.

Life-long updates

LXNAV offers free software updates for your devices.

IP64 protection class

The SmartSHUNT housing is protected according to IP64 standards.

Included in delivery

Smart Shunt, 1x temperature sensor with 4 mm ring cable lug, 1x 4-pin power connector, 1x USB stick for downloading the operating instructions

Note

The Smart Shunt is supplied with only one temperature sensor.
The 4-pole power plug is suitable for max. 2.5 mm² cables (without ferrule).
The latest operating instructions can be downloaded from the manufacturer's website.

Battery monitor for three batteries

Excellent battery monitor, even for three batteries. That's not something you see every day. Plus, it connects directly to the chartplotter via NMEA 2000 and to your mobile phone. It doesn't get any better than this.

Does what it's supposed to, very good service from Lxnav!

I finally got the Schunt working thanks to the great help from lxnav, but this required a software update which was available to download from the Lxnav website. Initially there were problems with the WiFi communication with my iPhone. I couldn't make the configurations using Safari. The solution was to switch to a different browser, Google Chrome, and it worked without any problems. The only problem is that on my B&G Vulkan the current is displayed with the wrong sign - negative when charging and positive when discharging. In the WiFi application it appears correct.

Fulfills the purpose exactly Problem-free installation

In contrast to the review of another customer, I can only say positive things about the product.
There are not many N2K-compatible shunts on the market. The LXNAV 300 fulfills the intended purpose exactly and can be easily configured to the battery conditions on board and delivers the measured values to any other N2K-compatible displays.
The installation and commissioning on my 36-foot cruising yacht were absolutely problem-free.

Faulty SW and unsuitable for sports boats

I have installed the SmartShunt 2 times. I exchanged the first one because I thought it was defective. The second had the same problem. I have 2x 200Ah lithium batteries as supply batteries and a Garmin system including a chart plotter with a NMEA 2000 network.
The SmartShunt comes with a USB stick that contains operating instructions and installation instructions for several LXNAV products, but not for the SmartShunt. You can only find them online in English. This means that it is not actually allowed to bear a CE label, since the safety information must always be in the national language.
You can only monitor a 12V battery. Three batteries can only be monitored if they are connected in series (12v24v36v). That may be interesting for solar systems, but I've seen a maximum of 24v on boats.
You can access the settings page with your smartphone via the WLAN interface. Battery type, capacity and alarm values can be entered on the page. If you then press the Save button, the data will not be saved. The preset lead acid battery with 100Ah was 0% after one day. The warning messages on the plotter are all cryptic and can only be understood by the developer himself.
The battery was then charged with the alternator and later with the charger. Unfortunately, the shunt did not notice that. The state of charge is still at 0%. I'm also not entirely sure if the instruments with the CAN bus are switched off on the ship and the charger is charging the batteries, whether the shunt is still active.
On the positive side, the mechanical design is very robust and well-designed.
Conclusion Here the developers have to do it again, it doesn't even have the quality of the first sample.

Our answer

Hallo Edzard,

der Hersteller hat uns folgendes Feedback zu Ihrer Bewertung zukommen lassen.

Aus dem englischen übersetzer Text:
Nach dem Feedback des Kunden haben wir unser Bestes getan, um direkt mit dem Kunden in Kontakt zu treten. Wir haben die 2 Geräte zurückerhalten und gemäß unseren internen Richtlinien vollständige Inspektions- und Testprotokolle durchgeführt. Nach einer Reihe von langen Tests haben wir festgestellt, dass beide SmartSHUNTs perfekt funktionieren und zeigen, dass die Spannungen 1, 2 und 3 gut funktionieren und stabil sind. Da der Kunde es mit 2x LXNAV SmartSHUNT versucht hat, der normal funktioniert, ist es möglich, dass das Gerät nicht mit der Installation des Kunden kompatibel ist. Bezüglich des Installationshandbuchs haben wir das Feedback des Kunden berücksichtigt und das Handbuch sofort überarbeitet und mit technischen Spezifikationen und Sprachen aktualisiert.
