Grid batteries are exposed to the full range of temperature swings of whatever climate they're installed in. Protecting a battery from the local climate is expensive and power intensive. Not a deal-breaker, but this cost needs to be factored into the cost of the battery, and any active cooling/heating needs to be deducted from its efficiency.
