## In short

The container is drawn to scale with its two banks of racks, 48 packs and 4,992 cells, the pack busbars, the high-voltage conductors, the cooling and the earth path. Layers can be peeled away, views switched, and two rack configurations compared. It exists so a buyer can see what five megawatt-hours is before sizing one.
## Facts

- The reference design is a 5 MWh containerised LFP battery with 48 packs and 4,992 cells across two banks of racks.

## Assumptions and limits

- A design concept, not a specification: thermal, fire, protection and grid-interface design are site- and vendor-specific.

## Questions and answers

**Battery or thermal storage?**  
Whichever moves the constraint. If the problem is heat arriving at the wrong time, a thermal store is usually cheaper per unit shifted; if it is demand charges or electrical matching, a battery.

**What decides storage economics?**  
Cost per kWh discharged over the asset's life — cycle count, depth and degradation — not capital cost per kWh installed. Arbitrage alone rarely carries the case.
