This EE claims, on a life cycle $/KWH basis, that in spite of the higher purchase cost of Li vs LA, the cost of Li Batteries is much lower than LA AGMs and even lower than FLA batteries.

Eg. $0.09/KWh for Li, vs an average of about $0.55 for three types of AGMs and $0.19 for FLAs.

This surprises me to say the least and was wondering if any folks here might be able to comment.
