Blue Pack™ Critical Power Battery

The Natron Blue Pack 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.
