Tesla overhauls Cybercab battery design, uses 4680 modules and weighs LFP switch

The company split 4680 battery cells into four separate modules, allowing faulty modules to be repaired or replaced without changing the whole pack. Executives also said the pack leaves room to potentially adopt lithium iron phosphate batteries in the future, though any switch from the current NMC chemistry and its timing are not decided.
