⚖️ Seller Warranty & Marketplace Dispute Conciliation

If, after following all self-resolution and verification steps, the controller exhibits persistent faults not caused by misuse, such as not recognizing the battery, not charging even with functioning panels, or showing visible internal component defects without signs of external impact, there may be a manufacturing defect justifying a warranty claim under the seller's warranty and marketplace return policy.
