Lithium battery systems offers significantly improved performance, when compared with lead acid battery systems. Lithium technology boasts superior cyclic life, where typical cyclic life can range from 4,000 – 6,000 cycles. Another core feature of lithium-based systems is the ability for the vast majority of the cell’s capacity to be fully utilised, irrespective of discharge rate; whereas AGM starts to see a drop in available capacity as the batteries start to be heavily loaded. The opposite is also true, where lithium systems can generally be charged at a quicker rate when compared with AGM, which normally results in more efficient use of charging sources.
Relative to AGM, lithium provides a more energy dense package and can result in significant weight reductions. A Battery Management System (BMS) is required for lithium storage to ensure cells are appropriately, charged/discharged, balanced and maintained.
