Reading this table

Usable, not nominal

What the battery delivers from full to empty under its own limits. The nominal figure on the box is what the cells hold.

The discharge power the battery holds hour after hour. Short peaks are on each battery's page.

Weight divided by usable energy, so a 5 kWh and a 15 kWh unit can be compared for what they ask of a wall or a floor.

The manufacturer did not publish it. We never estimate a missing value.
