Powering a Planet We Can’t Replace

N1C Lithium-Ion systems minimize their footprint, carbon emissions, and energy use due to their lighter weight, faster recharge rate, and higher temperature tolerance. They also function with a 15-year design life, eliminating the need to replace lead-acid batteries every few years, reducing the amount of toxic materials sent to landfills.
