QWORK Battery Monitor Voltmeter Ammeter for 8–100V Systems, 350A Shunt, Backlit LCD Panel-Mount

The QWORK Battery Monitor is a compact panel voltmeter/ammeter that shows real-time voltage, charge/discharge current, amp-hours and state-of-charge for 8–100V systems using an external 350A shunt and a 13 ft custom cable.

Keep precise electrical data at your fingertips with a monitoring unit built for mobile and off-grid power systems. This QWORK meter combines a clear backlit LCD, automatic memory, and a reinforced external shunt so you can read volts, amps and accumulated amp-hours without guessing. It mounts into a control panel and connects via the supplied heavy-duty cable, making it suitable for caravans, RVs, marine setups, small solar arrays and other DC battery banks.

How does this unit display and track battery information?

The monitor provides continuous readings of voltage, instantaneous current, and total amp-hours, with a digital state-of-charge estimate. The backlit LCD keeps information visible in low light and the instrument stores settings and last values even after power is removed.

• Voltage range support from 8V up to 100V for diverse battery types.
• Instant current measurement through the included 350A external shunt.
• Accumulated Ah counter to track capacity used or restored over time.
• Onboard memory retains calibration and last readings after shutdown.

What hardware and installation features should I expect?

The package includes a reinforced 350A shunt and a 13-foot custom cable for flexible placement between the monitor and the battery/shunt location. The meter is a compact panel-mount unit designed to sit flush with instrument panels and requires straightforward electrical connections.

• External heavy-duty shunt provides stable current sensing and thermal reliability.
• 13 ft (approx.) cable for easy routing to battery banks or shunt mounts.
• Panel-mount form factor fits standard control panels for clean integration.
• Clear wiring labels and simple connection sequence reduce installation time.

How accurate and durable is the QWORK monitor under heavy use?

Designed for demanding electrical systems, the reinforced shunt and internal circuitry prioritize stable readings and thermal resilience. While accuracy depends on correct shunt installation and wiring, the unit is built to maintain reliable measurements across typical mobile and off-grid conditions.

• Robust external shunt minimizes measurement drift under load.
• Backlit LCD engineered for readable contrast in various lighting.
• Automatic data memory reduces reset errors after power interruption.
• Durable enclosure and connectors suited for vehicle and marine environments.

What maintenance or user settings will I need to manage?

The monitor requires little day-to-day upkeep beyond occasional visual checks and ensuring clean shunt connections. User adjustments are limited to calibration and capacity parameters when first installed so the monitor calculates amp-hours and state-of-charge correctly for your battery bank.

• Set battery capacity (Ah) during initial setup for accurate SOC estimates.
• Periodically inspect shunt and cable terminals for secure, corrosion-free contacts.
• The memory chip stores configuration so recalibration is rarely needed.
• Firmware-free design keeps operation simple with no software updates required.

Who is this for: The QWORK Battery Monitor suits RV owners, vanlifers, boaters, solar homesteaders and technicians who need a compact, reliable instrument to monitor DC battery voltage, charge/discharge current and cumulative amp-hours. It’s aimed at anyone wanting a visible, panel-mounted gauge with a sturdy external shunt and long connection cable for flexible placement in varied mobile and off-grid power systems.
