Poor Bluetooth Connection
Previous version of the software worked well. Would allow you to locate device and maintained connection. New version is not able to find the device unless you remove and redownload the app. After connecting the first time it drops the connection and does not reconnect. There is no manual option to operate the charger which has made the device useless. Also has a strange requirement that clamps need to be unplugged to find Bluetooth device requiring a more complex sequence to find a device.

BT100W
The tester is great but the software is useless. Once you activate the Bluetooth function you can’t get out of it unless you turn your phone off or deactivate the Bluetooth app.
The tester says press exit to shut the app down but it turns back on by it self. The software / firmware does not work as described by it own menu. So if you want to just use the tester and not the Bluetooth you have to shut the app off on your phone or the tester won’t work. Useless software

No system test with PDF report
You cannot do a complete system test as on other devices, it only seems to store them as separate tests, cit would be a great improvement if you could. As ideally it needs to all be in a pdf you can save with the vehicle details eg Reg, mileage, VIN etc
Can’t use app
Please convert to English
Might be ok if you can read Chinese.
This app is all in Chinese and I couldn’t find an English app so completely useless for me
Apple
Works great with the BT 20
This app does not detect my BT Mobile Lite
Despite what the description says, I now have a little brick. This app does not detect my subject battery analyzer, even though it’s plugged into my car battery and I have a green light for power. It just stays stuck on the “Searching for available devices” screen. Please put out a reliable app!! Guess I’ll have to toss this brick in the garbage.

Bluetooth connectivity is a joke.
Once the device losses connection to the phone there is no way to recover other than to power cycle which interrupts the charging process. Very disappointing🤷🏼
Works pretty well so far so good,
The app works pretty well, though I would have preferred the BTMOBILE APP if I am being honest, what I don’t know is can the mobile BT battery tester be updated using the battery lab app, as you can update the battery tester using the BT MIBILE APP. Question why is the BT MOBILE APP not available on IOS devices.

Don’t buy TOPDON!
Bought BT20 a year ago and it had its own BT20 software in test flight that let me show customers real time battery data and very simple information to show them if battery is good or bad holding charge or not. 1 year later that software is not working and they came out with this junk that only says BASIC info… eg they want you to buy another product that they will iPHASEOUT in a year. Real nice.
