Q2: Is this battery safe for household or vehicle mounted use?
A2: Yes. It uses automotive‑grade LiFePO4 chemistry and passes strict safety tests including overcharge, over‑discharge, short circuit, crush, heating and temperature cycle. It will not explode or catch fire under conventional misuse conditions, making it highly safe for vehicle and household energy storage.
Q3: Will the battery get hot during normal use? Is high temperature dangerous?
A3: Slight temperature rise during charging/discharging is normal.
Safe working temperature: ≤60℃
When temperature exceeds 60℃, power will be limited to protect the cell
Continuous high temperature will accelerate aging and affect safety
We recommend equipped with thermal management or ventilation for high‑power scenarios.
Q4: Can I use this battery in high or low temperature environments?
A4: Yes, it has strong adaptability:
Discharge temperature: ‑35℃ ~ 60℃
