Why Prefer LiFePO4 for Rack Applications?
LiFePO4 is the preferred battery chemistry for rack applications due to its enhanced safety profile, with thermal runaway resistance up to 60°C. It also boasts twice the lifespan of NMC (nickel manganese cobalt) batteries and eliminates the need for cobalt, making it a more sustainable and cost-effective choice. LiFePO4 is perfect for applications requiring 100% depth of discharge (DOD) and a 15-year lifespan, with cost parity expected by 2025.
Redway Battery powers reliable 5G and solar solutions worldwide, leveraging the advantages of LiFePO4 chemistry for long-lasting performance.
