All the data can be displayed on the phone via Bluetooth. Easy car battery power management. ## Key features - Real-time voltage monitoring - Starting system testing - Charging system testing - Record start/stop times - Bluetooth data display - Battery power management ## Recent user reviews (10 of 32) All indexed reviews: https://appshunter.io/ios/app/ancel-bm200/id1669132898/reviews.md ### 3/5 — Communication Errors *2026-07-20, version 2.1.7* How about fixing the problem where when its running in the background its like you are in airplane mode no data, no phone calling, and no gps on your phone. If you kill bluetooth and this app connection is lost magically everything works again. ### 5/5 — Works great *2026-07-12, version 2.1.7* Have been using this for years now and works great. Works great on a lithium battery I have on my ATV, the agm on my truck ant the other two lead acids on my other cars. ### 2/5 — Quit *2026-07-04, version 2.1.7* After a few use the app quits an i have to reinstall it ### 1/5 — iOS app is not working 06.22.2026 *2026-06-23, version 2.1.7* When you first open the BM 200 app, it asked you to sign in using the email option does not work. It throws a network error. Using the Apple login also fails with a network error and you’re forced to use guest mode After you open the app, it wants you to scan the serial number on the item and this fails with network error Absolutely ridiculous ### 3/5 — Please add high voltage alarm! *2026-05-17, version 2.1.7* Please add alarm for overvoltage, needed if battery charging too much - this is why I bought the BM200. Very similar to low voltage alarm, just another slider user can set. Please and thank you! ### 4/5 — Nice device *2026-05-09, version 2.1.7* I’ve been using this for about a year now on a lead acid battery in an RV. I like that I can remotely read voltage but the SoC seems wonky to me. With a load on it and a battery voltage above 12 volts it says the SoC is 28%. Still very useful for voltage k storing in my application. ### 1/5 — DONT UPDATE YOURS!! *2026-05-08, version 2.1.7* New update completely made my unit not recognizable by Bluetooth anymore!!!! ### 2/5 — Some good some bad *2026-04-02, version 2.1.5* App generally works OK, except for the annoying frustration of being unable to delete any trips. Every time you go anywhere, the app logs a new trip, and there is no way to delete them or the history of your trips. Pretty significant oversight on the developers part. ### 5/5 — Power draw 1.5mA *2026-03-29, version 2.1.4* Great logger! SoC as a metric is flawed. What you really need is voltage over time, especially when the car is off. This module and app will store 30 days worth of data, and when you are within Bluetooth range, you can see the voltage graph which will help you diagnose what’s going on with your battery. If it’s below 11.8v when off, time to get a new battery in most cases. To the other fellow that gave this 1 star for always being on—first off, the draw is so small that it would literally take months and no driving at all to kill your battery. Secondly, if you are only reading your battery when the car is on, what’s the point?!? You are measuring your alternator or HV pack. ### 3/5 — Question mark bad position *2026-02-24, version 2.1.3* In the data view the voltage button is way to close of the question mark so we always hit it accidentally.
