Safety Recommendations

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

A BMS is essential when using a LFP battery to control voltage, current and temperature within the recommended limits.
