Fogstar Drift Gen2
Fogstar's second generation Drift leisure battery. Sensa reads the battery's own management system over Bluetooth so you can see its charge and cells from the dashboard.
Sensa Connection Method
Bluetooth.
Installation
Install it following Fogstar's instructions, within Bluetooth range of a Bluetooth proxy or the Sensa unit.
Configuration
There is no configuration necessary on the battery before adding to Sensa Nomad.
Adding to Sensa Nomad
Close the battery's phone app first, and disconnect anything else using its Bluetooth. The battery's management system allows only one Bluetooth connection at a time, so while another app or device is connected, Sensa cannot reach it.
Open Settings, choose the Devices tab, tick it under Discovered and press Add Selected Devices. If it is not there yet, press Scan.
See Adding devices for more.
What you see
Once the first reading arrives, the battery is named with its capacity, for example Fogstar 100Ah Leisure Battery, and appears on the BMS tab of the Habitation dashboard with:
- State of charge
- Voltage, current and power
- Remaining capacity and cycle count
- Each cell's voltage, and the spread between them
- Three temperatures: the pack, cell 1 and cell 2
- Whether charging and discharging are allowed, and whether it is balancing
Sensa reads the battery every 30 seconds.
Good to know
- No state of health. The battery does not report it, so that reading does not appear.
- It is watched for you. Cold-charging protection, Battery cell imbalance and Battery output turned off all work with it.
