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

Amazing piece of equipment! Using as a diagnostic tool for battery drain.

Chrysler Master Tech here using this as a diagnostic tool, on problem vehicles, that have an ignition off draw issue. 2025 Ram trucks have issues where the data bus will wake-up, and multiple modules will power up and drain the battery. These events are very random, from overnight to two weeks. I am getting +or- .001 amp accuracy after calibration w/60 amp internal shunt. Data log is not lost if battery goes dead. Voltage 2 can be used to monitor a suspect circuit for power up overnight. I have already discovered an astonishing amount of activity that occurs overnight, that is normal, on a "known good" vehicle. Thanks Thornwave!

Incredible product awesome customer service a very practical upgrade to your RV

Great product well engineered great customer service a great upgrade to any RV

Superb! Would not hesitate to buy again.

I have two Poermon Bluetooth LE monitors on my solsr/lithium battery systems in my teardrop camper and truck. They provide everything I need to operate these systems effectively and efficiently. I always know the key SOC and charging/discharging parameters via the app on my phone, and I love the logging function for checking the history. The resin encapsulation is another great selling point.
