In SSC there are two new battery life models for NMC Graphite NREL/ssc#579 and LMO LTO NREL/ssc#588 chemistries. These should be made available in SAM. Updates to LMO LTO defaults will be needed.
Also, battery thermal defaults for the size of the battery relative to the capacity should be updated for Commercial and utility-scale batteries. The current values are for residential-scale batteries and over-estimate the size of the battery for MW+ systems.
