How to decide

Define the job first: learning project, short outage backup, long-runtime backup, bill reduction or off-grid supply. Then compare measurable performance rather than marketing language.

The flywheel checkpoint

A flywheel is an energy-storage mechanism. It must receive energy before it can return energy. That principle should anchor any comparison involving a flywheel-based claim.
