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

Great Device

This is a great device and gives me all the data that I needed. Works as described. Only question I had, DS temp sensor hookup, and Thornwave Labs answered it promptly. Would definitely buy it again.

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!
