How it compares
Windrose Power vs. PU2000
Both are 2 MWh containerized battery systems. The key difference: Windrose Power is a mobile EV charging hub with built-in CCS and MCS guns. The PU2000 is a stationary grid-services BESS with higher AC discharge power but no onboard chargers.

LFP
Lithium Iron Phosphate
The iron–phosphate bond (Fe–PO₄) is one of the strongest in lithium-ion chemistry. Even at extreme temperatures, this bond holds its structure and does not release oxygen. Without free oxygen, the chain reaction that triggers thermal runaway — oxygen + heat + flammable electrolyte — cannot start. LFP is stable to ~270 °C before decomposing, vs. ~150 °C for NCA.
PU2000 · Battery Chemistry
NCA
Nickel Cobalt Aluminum
Nickel–cobalt oxide bonds release oxygen above ~150 °C. That oxygen reacts with the flammable electrolyte, generating heat that accelerates further decomposition — the exothermic cascade known as thermal runaway. Active cooling systems manage this risk under normal operation but cannot prevent it under severe abuse or failure.
Battery Lifetime: LFP vs NCA
At one full charge/discharge cycle per day, LFP reaches 8,000+ cycles in over 20 years with minimal capacity fade. NCA chemistry degrades faster under heavy daily cycling, typically reaching end-of-life around 8 years. LFP also carries no thermal runaway risk — a critical safety advantage for mobile, outdoor deployment.
