Why Max Charge Voltage and Min Discharge Voltage Matter
For LiFePO₄ batteries, Max Charge Voltage and Min Discharge Voltage are not just technical data — they reflect the consistency and balance of every single cell inside the pack.
When all cells reach the charging and discharging limits almost at the same time, it shows that the pack is perfectly matched, with highly uniform voltage and internal resistance. This means better efficiency, higher usable capacity, and a much longer lifespan.
At our factory, every battery pack is tested individually, and its Max Charge Voltage and Min Discharge Voltage results are published on our website for full transparency.
Most manufacturers do not share such detailed data — but we do, because we believe:
-- Real quality can be proven with real numbers
