If anyone is seeing a lot of high temperature charging (OTC) and high temperature discharging (OTD) alerts in the app then you may need a BMS firmware update from Fogstar. Apparently it only affects a recent small batch of 105Ah batteries. I’ve had to update my pair of batteries.
In the app, select the battery, go to About, Protect History. If you have a high number of OTC and OTD alerts, send a screenshot to Fogstar. They will then tell you if you need to update the BMS firmware and will send you the instructions.
To do the firmware update, you’ll need an Android phone that has Bluetooth 5 (I found my old phone with Bluetooth 4 didn’t work).
