PowerMon - Bluetooth LE Advanced Battery Monitor / DC Power Meter with data logging

Advanced battery monitor

With dual 64V voltage inputs and integrated 60A precision current sensing, PowerMon delivers complete battery analytics — including real-time voltage, current, power, lifetime energy tracking, amp-hour counting, state-of-charge calculation, accurate runtime prediction, and temperature.

Bluetooth connectivity

PowerMon includes a built-in Bluetooth® Low Energy (BLE) radio, enabling seamless connection to your smartphone or tablet for real-time battery monitoring. Install it inside a battery box or equipment bay and access performance data wirelessly — no need to open enclosures or run display cables.

Optional external shunt

Need to measure more than 60A? No problem. PowerMon can be connected to any external shunt rated up to 1000A or even more, enabling monitoring of high-current systems. For maximum installation flexibility, both the internal and external shunts can be installed on either the positive or negative side of the battery system.

Battery protection features

Don't leave your expensive batteries unprotected!

Paired with a relay, PowerMon can serve various functions, including acting as a low-voltage disconnect, high-voltage disconnect, over-current disconnect, low-temperature disconnect, high-temperature disconnect, or generator controller. And by the way, we also offer timer functionality.

Record exactly what your battery is doing — long term.

PowerMon features built-in data logging with up to three years of onboard storage. Unlike many competing products that store history inside the mobile app, PowerMon records data directly inside the device itself.

This means you do not need to keep a phone or tablet permanently connected to the monitor.

Whenever you connect via the mobile app, stored logs are automatically downloaded from the device.

PowerMon records:

• Voltage
  
• Current
  
• Power
  
• Temperature
  
• State-of-Charge (SOC)
  

The logging interval is user-configurable, from once per second to once per minute, allowing you to balance resolution and storage duration.

Automatic Generator Control

Enable the generator control feature and PowerMon can automatically start your generator when battery voltage or state-of-charge (SOC) drops below a user-defined threshold.

Maintain reliable power without constant supervision — PowerMon ensures your batteries are protected and recharged when needed.

Ultra-low power consumption

PowerMon operates on just 600uA of current. In fact, typical battery self-discharge exceeds the power required to run the device by at least one order of magnitude.

You get continuous monitoring without meaningfully impacting your battery capacity.

Optional color touchscreen display

PowerMon is also available with a dedicated display. The PowerMon-D4 features a 4.3-inch full-color touchscreen that connects wirelessly to your PowerMon via Bluetooth®.

The display also includes built-in Wi-Fi, with planned support for future cloud connectivity — enabling remote access and expanded monitoring capabilities.
