ANCEL BM200Blue 12V Battery Monitor

The ANCEL BM200Blue is a compact Bluetooth 12V battery monitor designed to keep tabs on lead‑acid and lithium vehicle batteries. It combines real time voltmeter readouts with recording and alarm functions, letting you check charge, cranking performance and charging system status without complicated tools. Use it in cars, vans, motorhomes, motorcycles, trucks and boats to spot faults early and manage battery health over time.

Key features

The BM200Blue records voltage history, trip traces and charging behaviour so you can review battery performance at a glance. The free ANCEL app for iOS and Android displays live data, stores logs for export to Excel and supports up to four devices per account. There is also an automatic alarm that notifies you via the app if voltage or power goes outside normal ranges. The unit supports a wide range of 12V battery types including flooded, AGM flat, AGM spiral, GEL and EFB, and the device is rated IP67 for resistance to dust and water.

Usage tips

Connect the monitor to the battery using the supplied leads and pair it to the ANCEL BM200Blue app following the quick start guide. Check the live voltage reading before and after starting the engine to run both cranking and charging tests, and use exported voltage history to spot gradual decline or intermittent faults. It’s a good fit if you want ongoing monitoring rather than occasional jump‑starting, and worth noting that the app supports multiple languages and family management of devices.

Care & maintenance

Keep the device mounted with the supplied 3M backing for a secure fit and avoid prolonged immersion despite the IP67 rating. Regularly review stored logs and update the app when prompted by your mobile platform to ensure alarms and exports work reliably.
