QWORK Battery Monitor Voltmeter Ammeter — 8–80V, up to 500A, 13 ft cable, backlit LCD & Ah tracking

QWORK's Battery Monitor is a compact voltmeter/ammeter that tracks battery voltage, charge/discharge current, and amp-hours so you can monitor energy use and avoid unexpected power loss.

This panel-mounted meter combines a clear backlit LCD with an external heavy-duty shunt and a long 13-foot cable to place the sensing hardware where it's most useful. It stores the last settings in built-in memory, reads battery voltage across a wide range, and reports cumulative amp-hours so you can understand both instantaneous load and overall battery capacity.

How does the QWORK monitor measure voltage and current?

The unit reads battery voltage across a broad range and uses an external shunt to convert high currents into measurable signals for the display. The reinforced shunt ensures stable, accurate readings in heavy-duty systems while the meter presents volts, amps and Ah on a single screen.

• Voltage measurement range suitable for many 12V/24V/48V battery systems
• External 350A shunt provides thermal and electrical stability
• Clear numeric readout for volts, amps and amp-hours

What installation options and wiring does it include?

QWORK supplies a 13-foot custom cable to separate the meter from the shunt and place the display where it's convenient. The compact panel-mount housing fits standard control panels and the external shunt mounts near battery busbars or fuse blocks for safe connection.

• 13 ft (approx.) cable for flexible placement of the display
• Panel mount dimensions for neat control-panel integration
• External shunt with heavy-gauge terminals for secure wiring

What features help with long-term battery management?

The monitor tracks cumulative amp-hours (Ah) and retains settings after power loss with an internal memory chip, so you won’t lose configuration or usage history after a disconnect. The backlit LCD keeps information readable in dim conditions, aiding overnight or low-light monitoring.

• Tracks Ah up to system limits to gauge remaining capacity
• Automatic memory saves last set parameters after power cut
• Backlit display for clear day-or-night visibility

How does this device fit into solar, RV or marine systems?

Designed for off-grid, mobile and stationary battery systems, the monitor handles the typical voltages and currents found in RVs, caravans, motorhomes and small solar storage banks. Use it to see charging, discharging and net energy transfer without replacing your existing battery infrastructure.

• Works with common battery bank configurations (RV, marine, solar setups)
• Monitors charging and discharging to help optimize system use
• Compact panel form factor for cockpit or control cabinet mounting

Who this is for: technicians, vanlifers, RV owners, boat skippers and small off-grid system operators who need an affordable, reliable display of battery status. If you want clear instant readings of voltage, current and cumulative amp-hours in a compact panel meter—with an external shunt and a long sensor cable for flexible placement—this QWORK monitor provides the practical monitoring tools to help manage power consumption and charging routines.
