Tesla designed Cybercab battery pack to support LFP chemistry
Tesla has revealed that the Cybercab battery pack was designed from the start to accommodate lithium iron phosphate (LFP) cells, giving it flexibility to change chemistry as production grows. According to a Munro Live factory tour, the current configuration is 88S6P, with 88 groups of six 4680 cells in parallel, and the enclosure has extra room and unused space beneath the modules to accommodate lower energy density chemistries without redesigning the pack. The Cybercab currently only uses 4680 cells.…
- The Cybercab pack uses an 88S6P layout and extra room for LFP cells.
- Today the Cybercab only uses 4680 cells; Tesla wants LFP as production scales.
- Modules can be replaced individually without discarding the entire pack.
🔎 Why it matters: Tesla designed the Cybercab pack with room for LFP cells, which would let it change chemistry as production scales without redesigning the pack.
📈 Upside: With spare room in the enclosure, switching to LFP would not require a full pack redesign, according to Tesla.
📉 Risk: LFP has lower energy density, so the same volume would store less energy than the current 4680 cells.
