FAQ: BMS Protection Boards

What's the typical lifespan of a quality BMS?

Properly designed units last 8-10 years with ≤2% annual capacity loss in 25°C environments.

Can I use the same BMS for LiFePO4 and NMC batteries?

Not recommended - different lithium chemistries require specific voltage thresholds and balancing strategies.

How critical is IP rating for stationary storage systems?

IP65 becomes essential in humid environments to prevent condensation-related failures.

What's the cost difference between passive and active balancing?

Active balancing adds 20-35% to BMS cost but improves system efficiency by 12-18%.
