Delivering the cornerstone for a carbon-neutral data center eco-system.

Industry-leading lifecycle power capacity

BluePack Critical Power Battery

The Natron BluePack battery is a 25kW, 48 volt building block for systems up to 812 volts. Standard configurations are 10-string for 480 volt critical power applications and 14-string configuration for 672 volt industrial applications. It is designed for extremely rapid charge/discharge, providing between 50,000 & 100,000 discharge cycles depending on application. It is incapable of thermal runaway and operates at extremely wide temperature ranges. Having twice the power of lithium-ion, it’s a safer alternative that is also responsibly and ethically sourced. This battery is designed for applications including Data Centers, UPSs, Telecom, EV Fast Charging, Fuel Cells, Motive/GSE, Industrial Power/Decarbonization, Grid Services – Peak Shaving, Dark Starting, Grid Forming, etc.
