BM200 Bluetooth 12V Vehicle Battery Monitor

See what your vehicle's 12 V battery has been doing between checks. The BM200 Bluetooth monitor sends battery readings to a phone app and keeps a history, helping you investigate low-charge, starting and charging concerns with more context.

✅ Follow changes instead of one spot reading - The app's history graphs show battery readings across the monitoring period.

✅ Review starting and charging behaviour - Cranking and charging test functions add information about the vehicle's electrical operation.

✅ Catch up after time away - The monitor stores up to 30 days of data before synchronization.

✅ Receive battery-condition alerts nearby - App notifications can flag abnormal readings while the phone is in Bluetooth range.

Give Battery Checks a History

A battery that seems fine during one check may behave differently during starting or after the vehicle has been parked. Keeping a record makes it easier to bring those events into the conversation when investigating an electrical problem.

Connect the monitor as instructed and use the phone app to review the data. Bluetooth notifications depend on range and phone permissions; this is not a remote cellular tracker. Charging-system testing supports ordinary alternators, not smart alternators.
