The XPAND Modular Pack (XMP) is the core building block of XALT Energy’s state of the art Energy Storage Systems (ESS) based on XALT Energy’s world class lithium-ion cell designs. XMP is designed for use in multiple applications including hybrid and electric commercial truck, bus and heavy-duty transportation; hybrid and electric marine power and propulsion, rail and mining applications.
Upgradeable, Ultra-Long Lifecycle
XMP core accommodates cells in XALT’s 225mm family without the need for retooling, anticipating a wide variety of application voltage, power, and energy. As cell technologies advance or packs become available for re-purposing, the XMP core can be replaced while all external interfaces remain the same.
Modular and Flexible Design
Easy to customize high voltage, low voltage and cooling interfaces to each application. All connections at front panel; rear access not needed for installation.
Advanced Thermal Management
XMP’s advanced active liquid cooling system maintains ideal cell temperatures throughout the pack and responds quickly to increases in power demand and changes in ambient (environmental) temperatures. Efficient direct liquid cooling prolongs cell life under the most demanding cycle profiles and severe environments, while maintaining full IP67 sealing performance.


The XMP96P sub-pack provides 9.6kWh total energy. With over 4.4C discharge and 3.9C charge capability, XMP96P is ideal for applications with high discharge power demands or intense regenerative capture.LEARN MORE »
