Description
The series is divided into two branches. LIM30HL is a high-power module for short discharges at high current, while LIM50EL with a capacity of 50 Ah is oriented towards energy storage. Each branch comes in versions of 8 and 12 cells, hence four voltage values, 28.8 V, 30.4 V, 43.2 V and 45.6 V. The chemistry is lithium manganese, which distinguishes the modules from the common LiFePO4. Cell balancing is built into the module, and the external LiBM control module with RS485 and CAN 2.0b interfaces combines up to 26 modules into one battery. For LIM30HL the manufacturer states up to 50 000 cycles in partial state of charge mode. The modules weigh 17.5–27 kg, with dimensions of 440×219×128 or 617×219×128 mm, which simplifies rack mounting compared with lead-acid batteries of similar energy.
How to choose
The module type determines the load profile. For a UPS, where the battery delivers power within minutes, take LIM30HL; for a storage unit with a long discharge, LIM50EL. The number of cells, 8 or 12, is selected for the bus voltage, and the number of modules in one system is limited to 26 per LiBM. If the project leans towards lead-acid technology, a similar role in a UPS is played by EN of the 12+ year class.
