Universal Battery Monitor for Multi-Voltage Systems
The Ancel BM300 Pro auto-detects 6V, 12V and 24V systems, covering classic cars, daily drivers, RVs, trucks and marine installations. It supports lead-acid Flooded, AGM, Gel, EFB and lithium chemistries. One unit monitors up to four batteries simultaneously from a single smartphone dashboard. This suits owners managing house and starter banks or dual-battery trucks who want consolidated voltage, state of charge and trend data without multiple devices.
IP67 Sealed Housing with Bluetooth 5.3 Connectivity
A reinforced composite shell rated IP67 resists water, dust, vibration and corrosion in harsh environments. Bluetooth 5.3 helps provide a more stable, longer-range link to the companion app for real-time alerts on abnormal voltage, charging faults and weak cranking performance. The monitor draws approximately 1mA, allowing permanent set-and-forget installation. Mounting away from thick metal obstructions ensures the best wireless signal for daily awareness.
Replaces Basic Voltmeters and Single-Battery Gauges
Unlike simple voltage-only displays, this unit adds charging and cranking tests on 12V and 24V systems with measurement accuracy above 99.6%. The upgrade is worth it when you need actionable diagnostics across mixed fleets or want early-warning notifications before a no-start event. Note that 6V systems support state of charge, voltage and temperature monitoring only, without charge or crank tests.

Questions about this item
How does Bluetooth 5.3 affect the connection range and stability?
Bluetooth 5.3 helps provide a more stable, longer-range connection between the monitor and the app, but mounting away from thick metal obstructions is still recommended for the best signal.
What are the physical dimensions and mounting requirements for the reinforced IP67 housing?
The unit measures 11 L x 2.5 W x 13 H centimeters with an IP67-sealed composite housing built to resist water, dust, vibration, and corrosion in harsh environments.
How is the BM300 Pro installed and what is the common mistake to avoid?
Install by connecting to the battery terminals for 6V, 12V, or 24V systems; the common mistake is mounting the unit behind thick metal obstructions which blocks the Bluetooth signal.
