The All in one BT608 battery tester is nice tool but who the H@ll wants to drop that kind of money for a tester if you aren't upselling batteries all day long? What happened to that basic BT506 you run off a Smart Phone App?
On second thoughts with all this Big Tech information monitoring and censorship going on , I would be more interested in getting this tool if the App that runs this device could just be incorporated seamlessly into my Maxi Sys Tablet like the Autel Maxi Scope and Digital Inspection Apps (and not require your Maxisys tablet to have an active update subscription for it to continue to work)
