CI-215 liquid-cooled battery cabinet (215 kWh)
215 kWh / 100 kW with liquid cooling — for sites running two cycles a day in a hot climate, where air cooling would leave the cells working at a temperature that costs years of life.

Why 3 °C matters more than it sounds
Cell life is sensitive to temperature, and the relationship is not linear. More important than the average temperature is the spread: if one module runs 10 °C hotter than its neighbours, that module ages faster, drags the string's usable capacity down with it, and becomes the failure point of the whole cabinet.
Liquid cooling holds the spread within about 3 °C, which is what allows a guaranteed throughput figure to be offered on a high-duty site. Air-cooled cabinets in the same duty can show a spread two or three times wider.
Duty cycle is the deciding question
One cycle per day in a temperate climate: air cooling is adequate, and the premium for liquid cooling buys little.
Two cycles per day, or continuous operation in a hot climate: liquid cooling is the engineering choice, and the temperature control is what makes the ten-year performance guarantee defensible rather than optimistic.
If you are not sure which category your site falls into, send the interval data and the site's ambient temperature profile. We will calculate the expected cell temperature under both options and tell you honestly which one the site needs.

Applications
Two-cycle-per-day industrial storage
Sites where the battery charges and discharges twice daily and cell temperature consistency is the limiting factor on life.
Hot-climate commercial storage
Where ambient temperature stays high year round and an air-cooled cabinet would run hot for months at a time.
Solar shifting at scale
Absorbs a large commercial array's midday output and discharges the full evening load.
