Battery Monitor

If you've got a dual battery setup, a battery monitor is your best mate for keeping tabs on what's actually happening with your power.

Without one, you're guessing. With one, you know exactly how much charge you've got left, how hard you're drawing, and whether you're about to run flat before sunrise. Our battery monitors give you real-time voltage, current draw, amp hours consumed, and remaining battery percentage on a backlit LCD screen you can read at a glance, day or night.

They're compatible with lithium and AGM batteries, 12V and 24V systems, and come with everything you need to get them wired in. Most include a shunt for accurate current measurement and a temperature sensor so you can keep an eye on battery health. Set custom alarms for over-voltage, under-voltage, over-current or high temps, and you'll know straight away if something's not right.

Installation is straightforward with colour-coded wiring, and once it's in you'll wonder how you managed without it. Pair your monitor with a quality DC-DC charger and you've got a complete power management system that keeps your lithium or AGM battery charged and protected. Add proper wiring and connectors to finish the job cleanly, and you're sorted.

Whether you're running a fridge, lights, a camp setup or all of the above, a battery monitor takes the guesswork out of managing your power so you can focus on the trip, not the battery.
