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:

Solutions for EV
Fast Charging

Reducing grid loads and demand charges.

Support multiple vehicle charges without expensive electric system upgrades.

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.

Natron Sodium-ion Battery Modules

Natron technology will be deployed with EV Fast Chargers on the University of California San Diego campus under a CEC grant. The batteries act as a reservoir of energy that can be tapped on demand to charge vehicles, much like the fuel storage tanks at gas stations. Natron’s battery recharges rapidly, and is ready to charge vehicles faster than any other battery technology.

Reduction in load to grid

Cycles for long project lifetimes

Better performance through better chemistry

Natron’s patented Prussian blue electrodes store and transfer sodium-ions faster, more often, and with lower internal resistance than any other commercial battery. With zero strain during charge / discharge, 10x faster cycling, and an over 50,000 cycle-life Natron’s sodium-ion batteries represent the future of industrial mobility.
