If you had the ability to put this in the background and send alerts when the battery reaches a settable low charge state, it would be utterly awesome. Yes I know you have to be within bluetooth range but that's ok. In addition being able to set/change the Bluetooth PIN is important and nobody does that -- without that ANYONE within range of a battery with this app can literally destroy it by setting BMS parameters deliberately wrong or just shutting off the FETs! ADD PIN CHANGE PLEASE!!

Location nag screen always runs. annoying. Also the cell balance function is undefined. can't predict what it will do. Balance on or off ok, but "Balance only when charging" flag has practically no effect, it's unpredictable. they replied to my feedback but nothing was done. version seems to be on ice.

Edit: The app can now see my two BMSs and the app shows the version mentioned by the developer. However, it cannot connect to the devices and read data from them. I tried uninstalling and re-installing with the same result. I get the message "no connected BMS". I, too, am having the problem that others are experiencing. The app continuously scans for Bluetooth devices but never finds anything. Due to company permissions on my new phone, I can only use apps from the Google Play Store.

We have updated the app to fix this issue, Can you please try again? Your app should say “V1.1.1 -V10” at the top of the HOME tab. If not, uninstall and reload from the play store. -Steve, Overkill Solar LLC
