LZY Energy exclusively uses LiFePO4 (LFP) batteries for all of its hybrid solar container power systems because of their long cycle life, excellent thermal stability, and superior safety over NMC batteries, as well as their lower cost of ownership over time.

LiFePO4 batteries are safer and more stable compared to conventional lithium-ion batteries thanks to the absence of cobalt and nickel. The lower energy density of a LiFePO4 power station also makes for better thermal and chemical stability.
