I have several new CATL M52280-E (770154-00204) liquid-cooled modules available in the Netherlands. The modules are unused in original packaging.
  • Capacity: 46.6 kWh
  • Configuration: 52S1P (280Ah prismatic cells)
  • Voltage: 166.4V Nominal
  • Thermal Management: Integrated liquid-cooling (water-glycol) + internal PTC heating strips for cold-weather charging.
  • BMS: The original CATL Master controllers (MBMU/SBMU) are proprietary and not available. Standard practice is to connect a third-party BMS.
  • Cooling: You will need an external circulation loop and chiller to utilize the liquid-cooling architecture.
  • Communication: The internal CSC uses NXP’s TPL (isoSPI) protocol. For most users, bypassing or translating the internal CSC to a third-party controller is the most viable path.
  • Weight: ~330 kg per module.
  • Location: The Netherlands.
  • Shipping: Worldwide (Freight). No sanctioned regions.
  • Status: New / Ready for immediate delivery.
  • Pricing: Depending on the quantity that you purchase.

If you’re looking for high-density LFP for a serious ESS project or an EV charging buffer, these are about as robust as it gets. PM or email (mike@tetromi.com) for a quote or technical questions.
