Note: LFP battery is safe and reliable at high temperatures for a long-life performance.
The SOA of Lithium Ion cells is bound by current, temperature and voltage.
- LFP cells may get damaged and may burst into flames if over charged above a recommended voltage.
- LFP batteries may get damaged if allowed to be discharged below a recommended cut-off voltage
- LFP batteries lifetime may get drastically reduced if operated beyond recommended temperature range.
- LFP batteries lifetime may get reduced if discharged at too high current or charged too fast.
LFP battery safety BMS is must.
- To prevent the voltage of any cell exceeding the limit
- To prevent the temperature of any cell exceeding the limit
- To prevent voltage dropping of any cell below a certain limit
- To prevent the charging current from exceeding the limit
- To prevent the discharging current from exceeding the limit
