[electricboats] NMC Onboard?

What are people's thoughts on the use of NMC versus LFP on a boat, for propulsive power?

NMC has considerably better energy density (by mass), but of course is less safe from a thermal-runaway standpoint.

The supplier I'm considering says the 'flash point' of his cells is 400C ("close to LFP" he says), but I see more like 300C for NMC and 500C for LFP (round numbers).

I'm attracted to the better energy density of NMC, but don't want to endanger our lives by moving to it.
