Frequently Asked Questions
Why is LiFePO4 chemistry preferred for commercial and residential energy storage?
LiFePO4 (lithium iron phosphate) features exceptional thermal stability with thermal runaway thresholds exceeding 270°C, zero oxygen release during puncture, and superior calendar life delivering over 3,500 to 6,000 cycles at 80% Depth of Discharge (DoD).
Can different capacity or aged LiFePO4 cells be mixed in series/parallel strings?
No. Mixing cells with differing capacities or internal resistance creates voltage imbalances, leading to premature BMS low-voltage cutoffs and localized cell degradation. All series cells must be factory-graded and strictly matched within 1% capacity and IR variance.
What active balancing specifications are recommended for large LiFePO4 battery modules?
For modules exceeding 100Ah capacity, an active balancing circuit with 1.0A to 2.0A transfer current is recommended over passive bleed balancing. This prevents cell drift during the steep voltage knee at the end of the charging curve.
