Kerry Wong documented a failure of his Cyclenbatt LiFePO4 battery after only a few dozen charge cycles, despite normal terminal voltage. The battery exhibited rapid voltage spike above 14V during charging attempts, suggesting an internal degradation or balance issue that rendered it non-functional despite appearing healthy on basic voltage checks.
