Announcement: Natron Energy currently offers BlueTray, BluePack, and BlueRack battery systems for use with industrial power equipment only. Natron Energy does not sell battery modules or battery cells as finished products. If you purchased any type of Natron battery or battery module from a 3rd party, please read this important disclaimer:

Reliable Performance & Uncompromising Safety

Natron’s sodium-ion battery packs the most peak-power and cycles safely into a production battery.

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.

Manufactured on Standard Production Lines

Sodium-ion batteries take advantage of standard lithium-ion pouch cell production lines while benefiting from a more sustainable chemistry. Natron’s cells do not rely on rare earth materials like cobalt nor do they have a long, questionable supply chain like lithium. Made from commodity materials including aluminum, iron, manganese, and sodium-ions (~68% of the earth’s surface is covered with salt water) Natron’s cells, modules, and battery represent a responsible alternative to lead and lithium batteries.

Volume Production Ready
Secure Supply Chain
Environmentally & Socially Responsible
Safe for Air Transport

After extensive market review and engineering studies we selected Natron’s BlueTray 4000 for our Edge Data Center applications instead of lead or lithium batteries as Natron provided a better fit to our workloads, higher peak capacity, a much wider temperature operating range that we need here in Arizona, and the flexibility to scale quickly.
