Includes heavy-gauge cabling with high-current DC connectors for simple installation.

Safty 4U Battery rack module

Lithium Iron batteries have superior chemical and thermal stability compared to other Lithium-ion batteries like those used in the Tesla Powerwall or LG Resu battery (those use more volatile lithium oxides). Overall, our Lithium Iron Phosphate are the safest in the lithium ion family. The 4U 48v 150ah form by 16S3P 3.2v 50Ah LiFePo4 cells. Totally 48pcs prismatic cells Inside the battery box.

4U 5.8kWh 51.2V 150Ah lithium battery pack with built in Battery managment system. This BMS allowed you connect the battery modular in series or in parallel to achieve different scale size.
