ANCEL BM200 PRO 12V Car Battery Monitor, 433MHz Wireless Battery Tester — Open-Box, 5% Off

【All-in-One Wireless Battery Monitor】ANCEL BM200 PRO is a 12V lead-acid battery monitor that integrates wireless transmission, multifunctional testing, and intelligent alerts to provide round-the-clock battery health protection for your vehicles, boats, and other motorized equipment. Supporting Type-C and solar power, it features high/low temperature and low voltage alarms,displaying real-time battery load tester 12v automotive health percentage, crank and charge test results, temperature, voltage, and RF signal strength.

【Real-time Monitoring, Worry-free Safety】ANCEL BM200 PRO consists of a wireless host and a wireless display screen, which refreshes 12v battery monitor of voltage, power, and temperature in real time every second to accurately capture every second of power changes. Once the battery tester experiences sudden temperature changes, abnormal voltage, or system failures, it immediately sounds an audible and visual alarm to help you respond in a timely manner and prevent potential problems.

【Automatic Start-stop of 12V Battery Monitor】Built-in high-sensitivity vibration sensor automatically starts car battery monitor when vibration is detected and continues to run for 5 minutes. If vibration is detected again during this period, the device will continue to operate; If no vibration is detected, it will automatically enter standby mode. This eliminates the need for manual switching and is more user-friendly. Note: The longer battery tester is connected, the more accurate the results will be.

【Environmentally Friendly & Energy Efficient】The 12 volt battery monitor display supports Type-C fast charging and dual power supply via solar panels. The solar charging design greatly reduces the hassle of frequent charging, making it both environmentally friendly and economical. The car battery tester uses flame-retardant casing and wiring, so it will not burn or melt even when the temperature around the engine is high, further enhancing safety performance.

【433MHz RF Transmission & Stable Signal Penetration】Utilizing stable 433MHz wireless transmission technology, the car battery monitor offers stronger penetration and longer transmission distances compared to bluetooth battery monitor. The signal is stable and energy-efficient, making it ideal for environments such as basements and garages. No need to connect to a smartphone or install an app—simply turn it on and use the smart battery monitor effortlessly.

【Comprehensive Protection & Wide Compatibility】The battery monitor is equipped with reverse connection protection, short circuit protection, arc-proof safety copper clamps, and built-in fuses, with IP67 waterproof design for stable and safe connections. Suitable for all types of 12V lead-acid batteries, including cars, motorcycles, RVs, trucks, SUVs, boats, yachts, lawn mowers, ATVs, and more, with one car battery monitor for multiple uses and comprehensive coverage.Note: Cranking test is not supported on some hybrid and all-electric RVs battery monitor.

【Simple Operation & Clear Data Display】The 12v battery monitor simply connect the terminals and place the display screen in front of the windshield to view 10 key data points in real time, including voltage, battery level, temperature, and health percentage. The top of the ancel battery tester's main unit is equipped with 9 LED status indicator lights, providing a clear overview of the battery tester condition.

The ANCEL BM200 PRO+ is an upgraded version of the 12V battery monitoring device with key features including SOH, SOC, temperature monitoring, voltage monitoring, and more, offering updated software, more powerful algorithms and a more compact chip
