Barely useful
On iOS the app must be manually closed, reopened and reconnected to the battery to show status. The screen is not what is shown here.Upgraded version worse
The older version could communicate with all my batteries, not the 1.5(7) version. The old version clearly graphically displays the % charge vs the new updateEG4 not communicating with battery
EG4 app IOS version loads but isn’t communicating with the battery. Bluetooth on. It “sees” two other BMSs in the area but not the EG4-LL or Lifepower 4 batteries.
