- Every cell voltage with minimum, maximum, difference and balancing
- Temperature sensors, alarms and BMS information
- Several batteries in one list, each with its own name
- Search for new devices can be switched off: only your own batteries stay in the list
- Session values and a CSV log of the readings
- History with charts and statistics: charge, power, voltage, temperatures and cells over a day, a week, a month or a year, energy per day, export as CSV
