Suer hot and 80% efficient must mean its also super insulated. For reference lithium batteries can be up to 99% efficient. I guess efficiency becomes less important if the power comes from renewable sources and the batteries are cheap. When excess renewable energy is available it makes absolute sense to use it rather than waste it.

Yup, cost is a big factor. 100% efficient batteries costing $40,000 or 80% efficient for $3,000 ....i ll go with the $3,000.
