FAQ
How should we compare cycle life claims?
Always request the test basis:
- Depth of discharge (DoD)
- Charge/discharge rate (C-rate)
- Temperature and rest periods
- End-of-life definition (e.g., 80% remaining capacity)
Numbers without context are not comparable and can hide accelerated aging risk.
What causes most integration failures?
Mismatch between inverter/charger behavior and BMS limits is the most common issue. Provide the exact inverter/charger model, target setpoints, peak loads, and operating temperature envelope to avoid surprises.
Why do batteries trip under high load even when capacity is sufficient?
Trips are usually driven by transient current peaks, cable/connector voltage drop, or thermal limits. Good BMS tuning coordinates overcurrent response timing with real peak events and includes controlled thermal derating.
What information do you need for a fit check?
- Target voltage and capacity
- Peak and continuous current profile
- Charger/inverter model numbers
- Duty cycle and charge windows
- Temperature envelope and enclosure constraints
- Communication requirements (CAN/RS485)
Which documents are most important for logistics and onboarding?
For most programs, procurement teams should request UN38.3 and MSDS for shipping workflows and CE-aligned documentation as applicable, plus labeling proofs tied to the final SKU.
Can you support EU delivery programs?
For stable demand, Poland Local Warehouse planning can shorten replenishment cycles and reduce lead time variability for qualified programs.
