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.

20-ft high-cube footprint delivers 5016 kWh, scalable by paralleling units.
Liquid-Cooled Thermal Management
60 kW chiller holds cells in the optimal temperature band, extending cycle life.
Three-Level BMS
Cell, cluster and container management with full SOC/SOH monitoring and protection.
Dual Fire Suppression
Perfluorohexanone PACK/cluster suppression plus water flooding for containment.
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.
