Bluetooth 12V Battery Monitor & Battery Tester Temperature Voltage Starting Test

Ancel BM200 Pro Functional advantages

    ✅12V Lead-Acid Battery Monitor: ANCEL BM200 Pro is a 12V lead-acid battery tester, which consists of a wireless host unit and a wireless display. It can display the voltage, power, temperature and health of the battery in real time, and automatically test the starting and charging systems of the vehicle. When the temperature is abnormal, low power, low voltage, startup system failure, charging system exceeds the normal range, the wireless display will automatically emit alarm sound to remind.

    ✅433MHZ Radio Frequency Transmission: Compared with Bluetooth, BM 200 Pro battery monitor adapt 433MHz RF technology has the advantages of better penetration ability, longer signal transmission distance( It can reach tens of meters), more energy saving and less signal interference, which is suitable for data transmission in any complex environment. Such as basement, stairwell, rural areas and any other places, etc.You do not need to connect to the network,phone and install the app.

    ✅Energy Saving And Environmental Protection: The car battery tester display screen adopts two modes of power supply:Type-C fast charging and solar panel. The solar panel powers and charges the device so that it does not need to be charged as often.The use of solar cells are more environmentally friendly, energy efficient, and can work independently of the grid.This is very useful for some remote areas or wilderness adventure and other scenarios.High economy can reduce energy costs.

    ✅Build-In Vibration Sensor: battery load tester with automatic on/off function. when BM200 Pro feels the vibration, it will automatically turn on and keep running for 5 minutes. If the device feels the vibration again within 5 minutes,it will continue to keep the power on. if no vibration occurs within 5 minutes,then BM200 Pro will automatically go into standby. Helping users to eliminate the step of turning off the device when it is not needed, thus improving the convenience of using the device.

    ✅Safety Protection & Wide Compatibility: Built-in fuse and reverse connection protection, unlike other car battery tester automotive, our ANCEL BM200 Pro digital car battery load tester all batteries are equipped with 100% high quality safety copper clips with reverse polarity protection and spark protection for stable and safe connection during testing. Suitable for all 12V lead-acid batteries, such as: cars, motorcycles, trucks, RVs, ATVs, suv's, boats, yachts, lawn mowers, etc.

    ✅Easy Operation And Battery Health Status Indicator: You only need to connect the negative (black) connector firmly to the negative battery port and the positive (red) connector firmly to the positive battery port. Place the LCD display in front of the windshield to view battery health data such as: voltage, power percentage, temperature, charging system test, starting system test, health percentage, etc. Battery status can also be displayed by the 9 LED light on top of the wireless host unit.

    ✅Type-C charging/solar powered ✅ high temperature/low voltage alarm warning ✅ Support real-time data viewing, ANCEL BM200 PRO Car Battery Tester Battery Monitor display can display 1. Battery Health Percentage 2.Battery Test results 3.Start test alert 4. Charge test alert 5.Temperature 6. Charging percentage 7.Voltage 8.Starting voltage 9.RF signal 10. Battery test results

    🔔 Warm Tips: ❗ ANCEL BM200 Pro only supports monitoring of 12v lead-acid battery; ❗Ensure that the device is securely installed for the first time. Loose installation may cause abnormal data capture and display. At the same time, when there is a 433MHZ RF Transmission Signal Icon in the upper right corner of the display, it means that the monitor and the display are successfully connected, and the display can display monitoring data in real time, otherwise it may lead to inaccurate display data.❗The cranking voltage is the data of the moment the car starts. So after the test, the data will not change basically, unless the car is restarted.
