4000+ Cycle Life

The EV LF50F cell is specified for more than 4000 cycles under suitable test and operating conditions.

Actual battery life depends on several factors, including:

Depth of discharge

Charging voltage

Charging current

Discharge current

Operating temperature

Cell balancing

BMS settings

Storage conditions

Proper battery design and correct charging parameters are important for achieving long-term performance.

Low Internal Resistance

The cell specification indicates internal resistance of ≤0.7mΩ.

Low internal resistance can help reduce internal voltage drop and heat generation during current flow.

Actual resistance can vary depending on:

Cell temperature

State of charge

Measurement method

Cell age

Operating conditions

For multi-cell battery packs, proper cell matching is recommended.

1C Maximum Discharge Rate

The specified maximum discharge rate is 1C.

For a 50Ah cell:

50Ah × 1C = 50A

Therefore, based on the stated 1C specification, the cell's maximum discharge current is approximately 50A.

The final battery pack's allowable current must also consider the BMS, busbars, cables, terminals, connections and inverter/motor requirements.

Maximum Charge Voltage

The maximum charge voltage specified for the cell is:

3.65V per cell

A complete battery pack must use the appropriate charging voltage according to the number of cells connected in series and the manufacturer's recommended charging parameters.

A suitable LiFePO4 charger and BMS should always be used.

Temperature Range

The provided specification lists a discharging temperature range of:

-30°C to 60°C

Actual charging temperature requirements should be followed according to the manufacturer's specification and the final battery/BMS design.

Operating outside recommended temperature limits can affect safety, performance and cycle life.
