If as SoS explains, the loom above the cells is sensory, they are connected to each indvidual cell. They are perhaps copper, and appear to be insulated in pretty standard fashion. Once enough heat is acquired, and the insulation fails, don't we have "Inter connectivity"? This eliminates the ability to monitor in isolation, and if the loom also carries the charging current, doesn't this exacerbate the possibility for fire, and explosion? Should the "Loom" be better protected against this type of failure? With diodes, or at least segregated leads?
