BESS isn't inherently bad, but needs to be treated with respect. LFP packs need continuous igniters and NMC packs need combustibles-free clearance, and both need deflagration gases ventilation.
Agreed. Specifically, these are lithium-ion rather than the new lithium iron phosphates which have none of those issues. No one should be doing lithium-ion for new installations. Lithium ions are only viable in cars which need the lower weight limits.
