Lithium Batteries

Lithium iron phosphate (LiFePO4) and increasingly also lithium manganese cobalt (LMC) battery systems are the modern basis for professional power supply. They possess outstanding properties such as very high charging and discharging currents with very good voltage stability, enabling a powerful and safe system. The lifespan is significantly higher compared to conventional lead-acid batteries.

• Short charging times due to charging currents up to 1 C

Charging can be done with a normal GEL/AGM battery charger and adapted characteristic curve below 0°C. At lower temperatures, charging should only be done with a maximum of 0.1 C.

• Maximum power during entire discharge

The high current delivery capability of 1C - 3C continuously and short-term up to 10C provides maximum power until complete discharge (no "voltage or capacity drop" as with lead-acid batteries), making it very attractive for applications with high current consumers and chargers, such as with Combi inverters.

• Very low self-discharge < 3% per month

In contrast to lead-acid batteries, lithium iron phosphate batteries can also be stored in a partially discharged state for a longer period without permanent damage.

• Up to 70% weight and space savings

A 210 Ah LiFePO4 battery weighs 23 kg compared to a lead-acid battery of 70 kg with the same nominal capacity.

• All available capacity can be used

The full battery capacity is available, whereas with lead-acid batteries, only about 50% of the nominal capacity is actually available.

Control and Monitoring

The integrated battery management system (BMS), in conjunction with an internal or external relay, protects the lithium cells from overcharging and deep discharging and monitors cell temperature. Individual cell balancing is also performed.
