Tunnel Tractor Battery 537V420Ah
Tunnel Tractor Battery 537V420Ah
Designed to be "Deep-cycle" that means the battery system can be discharged until almost empty, voltage nominal 537V and energy is 225kWh.
A+ class LiFePO4(Lithium Iron Phosphate) cells, up to 3000cycles(8-10years). The capacity remains higher than 80% after 2000+cycles, even after 3500+cycles(10-12years), the capacity can still be over 70%.
Battery cells packing process is completely in accordance with the standards of EV Battery production, embracing the laser welding techniques to ensure every cell to be soldered completely, avoiding insufficient or poor soldering.
