Lithium batteries

Lithium batteries

Lithium iron phosphate (LiFePO4) and increasingly lithium manganese cobalt (LMC) battery systems form the modern basis for professional power supplies. They possess outstanding properties such as very high charging and discharging currents with excellent voltage stability, enabling a high-performance and safe system. Their lifespan is significantly longer compared to conventional lead-acid batteries.

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

Charging can be carried out below 0°C using a standard GEL/AGM battery charger with an adapted charging curve. At lower temperatures, charging must be limited to a maximum rate of 0.1C.

• Maximum power throughout the entire discharge

The high current output capability of 1C - 3C continuously and up to 10C for short periods means that maximum power is available until complete discharge (no "voltage or capacity drop", as with lead-acid batteries) and makes the application with high-current consumers and chargers, as is the case with e.g. Komi inverters, very interesting.

• Very low self-discharge < 3% per month

Unlike lead-acid batteries, lithium iron phosphate batteries can be stored in a partially discharged state for extended periods without permanent damage.

• Up to 70% weight and space savings

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

• Fully utilized existing capacity

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 the cell temperature. Individual cell balancing is also performed.
