What are the main differences between VRLA and Lithium-ion batteries in UPS applications?

The choice between Valve-Regulated Lead-Acid (VRLA) and Lithium-ion (Li-ion NMC or LFP) batteries involves several key differences:Lifespan: VRLA typically lasts 3-5 years at 77°F (25°C), while Li-ion offers 8-12 years.Temperature sensitivity: VRLA life halves for every 18°F (10°C) above 77°F; Li-ion tolerates heat better but still prefers 68-77°F.Energy density: Li-ion provides higher energy density, meaning...

What are common pitfalls to avoid when adopting industrial LiFePO4 battery packs?

Adoption pitfalls include:Assuming Uniform Performance: Cell grade, BMS quality, and operating windows significantly impact year-8 capacity. Demand throughput warranties and independent test data.Overemphasizing Energy Density: Industrial applications prioritize safety, cycle life, and cost per kWh over Wh/kg. LFP’s lower density is offset by its stability.Ignoring Cold Weather: Charging below 0°C without heaters risks lithium plating....
