A blue connect thrown in for a few extra bucks is a bonus. I lost connection and just deleted app then downloaded again to get it to work. HOPEFULLY TGE COMPANY WILL CONTINUE TO UPGRADE THIS BONUS FEATURE (hint) I own over ten of these no BMS issues. ### 1/5 — Other apps work *2026-01-13* Other battery apps picked up my vatrer 560ah immediately. This does not. ### 1/5 — No connection *2025-10-23* Bought two 460ah batteries. One connected to Bluetooth and one won’t. Have tried connecting from 3 to 5 meters away like the tech asked, no go, delegated app and re installed it twice both on my iPhone and iPad and still won’t connect to one of the batteries! They want me to send pictures of the “parameters”but I don’t know what that means. ### 2/5 — Needs more info *2025-09-15* App does connect most of the time. Shows some stats. Will not show Discharging or Charging state. Also no security on blue tooth. Should have password. Also control of heating? Or at least show heater on/off. Good start keep updating it. ### 1/5 — Buggy *2025-09-06* Rarely works and is very limited when it does. Love the battery though. ### 2/5 — Won’t find batteries on Bluetooth. *2025-08-02* I have two Vatrer 12v 460Ah batteries and for some reason this app does not see them. Other battery apps can see my batteries but not this app ### 1/5 — Vatrer *2025-08-01* App downloaded but won’t connect. Checked Bluetooth permissions etc. it’s a no go ### 5/5 — Great! *2025-07-04* Connect to battery quickly and shows all the needed info.
