BATTERY FEATURES
Technical Support FAQ
Q1
What international certifications have your LFP cells passed?
Our cells comply with major international standards, including UN38.3, UL1642, IEC 62619, and CE/RoHS.
Q2
How do LFP cells perform under extreme temperatures?
The thermal runaway temperature is above 500°C. We use relief valves and flame-retardant materials to ensure safety under extreme conditions.
Q3
What is the cycle life of your battery cells?
Under standard conditions, our cells achieve 3,500 to 6,000+ cycles with capacity retention of at least 80%.
Q4
What charge and discharge rates (C-rate) are supported?
We offer Energy Type (1C) for ESS and Power Type (3C-5C) for high-demand industrial applications.
Q5
What are the TCO advantages of LFP compared to NCM?
LFP is cobalt/nickel-free and lasts 2-3x longer, significantly lowering the LCOE (Levelized Cost of Energy) over the full life cycle.
Q6
What is your Minimum Order Quantity (MOQ)?
We support Small Batch trial production. Formal order MOQ is typically by Pallet, depending on cell specifications.
