The EVE LF334 is a prismatic lithium iron phosphate battery cell featuring pre-welded M6 studs; this eliminates the need for specialized welding equipment, allowing for direct DIY assembly. With a continuous charge/discharge rate of 1C and a pulse discharge rate of 3C, this cell model is suitable for use in both Electric Vehicles (EV) and Energy Storage Systems (ESS).

Compared to the MB31 cell, the LF334 cell offers higher discharge and charge rates, making it suitable for both residential energy storage systems(ESS) and EVs.
The LF334 cell also boasts a wider temperature range, with a charging temperature range of -10 to 65°C and a discharging temperature range of -35 to 65°C.
It's important to note that MB31 and LF334 cells differ slightly in their cycle lifetime representation.
MB31 cycle lifetime: After 8000 cycles, the actual remaining capacity is greater than 70%.
LF334 cycle lifetime: After 4000 cycles, the actual remaining capacity is greater than 80%.
The LF334 has an original factory QR code on the top, and all cells have been tested and are traceable. Original factory test data sheets are available.

One carton contains 4 LF334 cells + 4 busbars + 4 epoxy plates + 8 flange nuts
busbar dimension:90*20*2mm,material:copper
epoxy plate dimension:200*170*0.5mm



Although the EVE LF334 datasheet specifies a charging temperature range of -10°C to 65°C, the table regarding continuous charging modes indicates that the charging rate is restricted within the -10°C to 0°C range.
