Thermal anomalies may go undetected with traditional temperature sensors as air conditioning units will try to compensate the heat problem. The thermal camera sensor looks at the batteries and monitors its surface temperature in 4800 points, every 2 seconds.

Corrosive gasses enter your BESS through outside air exchange.
Sulfur dioxide (SO2) and hydrogen sulfide (H2S) gasses are known for their aggressiveness towards steel and other metal alloys. While the compound in its pure form does not react strongly with metal, it can be highly corrosive when exposed to the atmosphere.
