A 0 to 500 A shunt monitor for 8 to 120 V systems rated IP68, with an LCD showing state of charge, voltage, current, power and time remaining, and a user-set low-capacity buzzer.
The bottom line The best-sealed monitor here, with its displayed values listed and a settable alarm. It names no chemistry, publishes no accuracy figure and keeps no history — three things its shelf-mates manage between them.
A 500 A monitor built to get wet.
IP68
On the display, in high-quality polycarbonate, dust-tight and rated for immersion. Five monitors in this family and one publishes an ingress rating. For a boat, an open locker or a trailer, that is the specification that decides survival.
What it shows
State of charge, voltage, current, power and remaining time, itemised in the first bullet. Knowing what appears on a display before buying is more useful than knowing that it has one.
The buzzer
Every ten seconds at a level the user sets. Audible rather than visual, which matters on an instrument mounted where nobody is looking.
The lines this listing leaves blank
Chemistries. Accuracy. Self-consumption. Any history. The Victron in this family keeps historical data and the ECO-WORTHY publishes its own draw; this one does neither.
Availability
German and French Amazon stores quoted about 80 € when this page was compiled.
American and British Amazon stores carry it too, priced in their own currency, which the euro range above deliberately omits.
Spanish Amazon store wanted more than 1.6× what the cheapest country wanted. A margin that wide usually means stock shipped in from elsewhere rather than a seller on the ground, so that quote stays out of the range above.
Italian Amazon catalogue carries an entry for it, with nobody selling.

What it gets right, and what it leaves out
Strengths
IP68 on the display, which is the highest ingress rating in this family
The displayed values are itemised — state of charge, voltage, current, power, remaining time
A user-settable alarm level rather than a fixed threshold
Compromises
No chemistries named, so how it handles a lithium bank is unstated
No self-consumption and no accuracy figure
No application, and no data history

Questions owners ask about this one
Why does IP68 matter on a display?
Because a battery monitor is mounted where it can be read, which on a boat or in a van locker is often where water goes. IP68 means dust-tight and rated for immersion, which is more than the other four monitors in this family publish.
What does “remaining time” actually measure?
The monitor divides the energy it counts as remaining by the current currently flowing. It is accurate while the load is steady and moves sharply when the load changes — which is why it is a guide rather than a promise.
shunt-based counting · 300 A shunt · accuracy not published · chemistries not named, custom parameters supported · 3.5-inch colour touchscreen with adjustable brightness · no app named · voltage, current and temperature alarms · 0.5 mA self-consumption, PUBLISHED · installation requirements not described
A 300 A shunt monitor with a 3.5-inch colour touchscreen and a published self-consumption of 0.5 mA — the only self-consumption figure in this catalogue.
Best for: A system where the monitor itself must not be part of the standing drain.
shunt-based counting · 500 A shunt, M8 connection · accuracy not published · LiFePO4, lithium-ion, AGM, gel and lead-acid · backlit LCD · no app named · flashing display and buzzer every 10 seconds at a set threshold · self-consumption not published · 0–9999 Ah capacity range
A 500 A shunt monitor for 8 to 120 V systems with M8 terminals, five named chemistries, a capacity range to 9999 Ah and a backlit LCD with a buzzer alarm.
Best for: A large mixed-chemistry installation where the terminal size has to be known in advance.
shunt-based counting · 500 A shunt · accuracy described as high, no figure · LiFePO4, AGM, sealed, gel and flooded · display included · no app named · programmable high and low voltage alarm · self-consumption not published · installation requirements not described
A 500 A shunt battery monitor for 12 to 48 V systems with a programmable high and low capacity alarm, custom battery parameters and a memory that survives a power interruption.
Best for: A bank whose chemistry is unusual enough to need custom parameters.
