What the desk does
We ask buyers for rated capacity at a stated load center, battery voltage, amp-hour rating, tray size, quantity and destination. We then ask factories to quote those axes and to name exclusions for freight, charger and room work. Comparison is on total procurement scope, not a headline tray price. If two replies differ only because one omitted a charger or a UN38.3 file, we send the shorter reply back instead of treating it as a market win.
