500A Battery Monitor With Shunt

If you're serious about keeping tabs on your battery system, a proper battery monitor is non-negotiable. It's the difference between confidently knowing exactly what's left in the tank and guessing whether you've got enough juice to run the fridge overnight.

Our battery monitors with built-in 500A shunts give you real-time data on everything that matters. Voltage, amps, power draw, amp hours consumed, temperature, and remaining battery percentage all displayed on a backlit LCD screen. No more stabbing in the dark with a basic voltmeter. You'll know exactly how much power you're pulling, how much is left, and how long it'll last.

The 500A shunt handles high current loads without breaking a sweat, which means it's ideal for setups running fridges, inverters, lighting and whatever else you've got wired up. Whether you're running lithium batteries or AGM, 12V or 24V systems, these monitors are compatible and straightforward to set up with the included temperature sensor.

Settable alarms give you a heads-up before things go sideways. Over-voltage, under-voltage, over-current, over-temperature - configure your thresholds and you'll get an alert if something's not right. It's the kind of insight that helps you avoid getting caught short and keeps your battery system healthy for the long haul.

Installation pairs nicely with our wiring kits and connectors, and if you're building out a full dual battery system, it makes sense to look at pairing your monitor with a quality DC-DC charger to keep everything topped up while you're on the move.
