Lithium battery fire extinguisher???

[Pye_End]

They are far safer than lead acid batteries

The detail of this comment might make interesting analysis, but perhaps a rabbit hole for another time.

The authors created an entirely unrealistic scenario

Prejudgement rarely provokes a healthy nursery for new information. No surprises there.

Nobody has yet shown a real example of a problem,

In your experience. Not mine.

Safety is one of the advantages over lead, not the other way around.

OP asked about fire control for LFP, not how it compares with LA.

I have Victron Lithium batteries on my boat and was looking to upgrade the fire protection with a special lithium battery fire extinguisher.
However on reading the information about them I dont see how it would work on my boat as the contents need to smother the battery.
The batteries are housed in a strong plywood box with a few fairly inaccessible holes in the sides for wire access.
If the worst happened and the batteries do catch fire how would the 'special 'foam in the extinguisher smother the battery fire when the box is surrounding them.
If the fire is bad enough to have burnt the box away there is no way I would be lifting the floor boards up to gain access to the compartment

I think instead of considering the batteries the source of the fire perhaps the solution should be to protect the lithium batteries from a fire originating elsewhere .
