Are home batteries safe in hot Australia summers?

I live in Darwin and I'm thinking about getting a home battery system. I've never owned one before, so I'm a bit nervous about the safety side of things especially with the heat.

I do have a portable solar power station, but that stays inside so I’m not too worried. The home battery would be mounted outside, and as anyone in Darwin knows, it gets really hot here.

Am I worrying for nothing or are my concerns actually valid?
