Imperium lithium batteries are lithium-iron phosphate (LiFePO4) batteries. LiFePO4 is the safest and best performing of all the lithium-ion battery types. Besides safety, LiFePO4 technology batteries are characterized by:
- Minimal weight
- Small dimensions
- Low internal resistance
- High efficiency
- Excellent cycle performance
- Large permitted temperature range
- Almost constant voltage throughout the entire discharge cycle
- It is possible to use 100% of the capacity before the battery is empty and switches itself off. This is in contrast to AGM lead-acid batteries where usually 50 – 60% of the capacity can be used before the battery needs to be recharged.
A big advantage of LiFePO4 batteries compared to AGM lead-acid batteries is that the LiFePO4 battery does not need to be fully charged, whereas an AGM lead-acid battery will fail due to sulphating if it is not fully charged for a long period of time.
