Energy Storage Containers
2 Product Series · 5 Models available
The energy storage container packages battery, power conversion, thermal management and fire protection into a single factory-built, transportable unit. QDTB's liquid-cooled 20-ft high-cube container delivers up to 2.5 MW / 5 MWh per unit using 0.5P LiFePO4 cells (3.2 V / 314 Ah), arranged in 1P104S packs and 1P416S clusters for 5016 kWh at 1331.2 Vdc. A three-level BMS (cell–cluster–container), a 60 kW liquid chiller and dual perfluorohexanone-plus-water fire suppression keep the battery inside its safe operating window across -20 to 50 °C. Pre-integrated and factory-tested, the container drops onto a prepared pad and energises in days — the fastest route to grid-scale, commercial or microgrid storage.

Frequently Asked Questions
Why liquid cooling instead of air cooling?
Liquid cooling keeps cell temperature more uniform, supports higher energy density and prolongs cycle life, especially in hot climates.
How much energy does one container hold?
A single 20-ft unit is rated 2.5 MW / 5 MWh (5016 kWh at 1331.2 Vdc), scalable to larger capacities by paralleling containers.
What battery cells are used?
0.5P LiFePO4 cells of 3.2 V / 314 Ah, chosen for thermal stability and long cycle life.
How does the fire protection work?
Combined detectors inside each PACK trigger perfluorohexanone discharge at PACK/cluster level, with a water-flooding system as a final containment layer.
What is the operating temperature range?
The container operates from -20 to 50 °C, with derating above 45 °C, and is IP54-rated (IP55 optional) for outdoor installation.
What is the minimum order quantity (MOQ) for Energy Storage Containers?
One unit for standard products. Custom-designed equipment is quoted on specifications — send your parameters or drawings and our sales team will confirm the MOQ for your configuration.

Liquid-Cooled vs Air-Cooled vs Skid Cabinet: How to Choose
| Liquid-Cooled Container | Air-Cooled Container | Skid-Mounted Cabinet | |
|---|---|---|---|
| Thermal uniformity | Coolant keeps cell temperatures close across the rack | Airflow leaves hotspots between packs | Cabinet cooling, sized to a smaller bank |
| Energy density | Highest, because packs sit closer together | Lower, since air channels need space | Lowest per unit footprint |
| Auxiliary power | Chiller draws power continuously | Fans draw less, but cooling is less effective in heat | Small fans or a compact chiller |
| Environment range | Holds the battery window across a wide ambient band | Derates earlier in high ambient | Suited to moderate climates |
| Maintenance | Coolant circuit and chiller need scheduled checks | Filter and fan servicing | Simple access, small spare list |
| Cost | Highest per kWh installed | Lower, with a shorter service life in heat | Lowest, at the smallest scale |
| Typical application | Grid-scale and large C&I storage | Moderate-climate C&I storage | Microgrids and small commercial sites |
Where QDTB® Energy Storage Containers Are Specified
A storage container is specified when a plant needs megawatt-scale capacity delivered as one tested unit: grid-side storage, commercial and industrial sites, renewable integration and microgrids. Battery, power conversion, thermal management and fire protection arrive in one enclosure, so site work is a pad, a cable connection and commissioning rather than a construction project.
Liquid cooling is what makes the footprint practical at this scale, because it keeps cell temperatures uniform across a densely packed rack. Uniform temperature is also what protects cycle life — a bank that runs a few degrees hotter in one corner ages faster than its warranty assumes.
The 20-ft unit carries 2.5 MW / 5 MWh with LFP cells, a three-level BMS and dual perfluorohexanone plus water suppression, and holds the battery inside its safe window from -20 to 50 °C. Above 45 °C the unit derates rather than pushing the cells outside their limits.
Solar-plus-storage and backup schemes use the same container as the energy block, sized on usable energy and the plant's dispatch profile. Pre-integration is what shortens the schedule: the container is factory-tested, so energisation is measured in days after the pad is ready.
