3.2 ANCEL BM200 Pro Battery Monitor Operations
The BM200 Pro continuously monitors your battery and vehicle systems:
- Real-time Monitoring: The display unit shows current battery voltage, state of health (SoH), state of charge (SoC), and temperature.
- Battery Test: Provides a quick snapshot of your battery's health percentages and test results to confirm its status.
- Cranking Test: Automatically tests the starting system when the engine starts, displaying cranking voltage and determining if the starting is abnormal.
- Charging Test: Monitors the charging system after the car starts, displaying the charging percentage in real-time and assessing the alternator's working condition.
- Alarm Function: The wireless display emits an alarm sound to alert you when conditions are abnormal, such as low power, low voltage, high temperature, startup system failure, or charging system exceeding the normal range.
- Wireless Transmission: Utilizes 433MHz wireless radio frequency for stable transmission between the battery monitor and the display unit, with a range of 30-70 feet.
- Charging Modes: The display unit supports two charging methods: solar charging via its built-in solar panel and Type-C (5V charger) for simultaneous charging.
