Pre‑Purchase Notice – Clearance Sale (Used / Returned Batteries)

Thank you for your interest in our clearance inventory. To help you make an informed decision, please read the following important notes before placing your order.

These batteries are second‑hand / customer‑returned / minor‑defective units, offered at a 40‑60% discount off the original price for quick stock liquidation.

Please be aware that:

  • Packaging may be damaged – outer boxes or internal protective materials may show signs of wear, tear, or repacking.
  • Accessories may be missing – some units may not include all original cables, brackets, manuals, or mounting hardware. Please check the contents upon receipt and verify against the product listing.
  • Cosmetic imperfections – scratches, dents, or other surface blemishes are common and do not affect core functionality, but they are not covered under our standard aesthetic warranty.

We strongly recommend this offer for:

  • Buyers with basic technical knowledge of battery systems, especially the ability to inspect, test, and safely handle LiFePO₄ batteries.
  • Users who are comfortable with disassembly or repair (if needed) and can make use of second‑hand battery cells for DIY projects, off‑grid setups, or backup systems.
  • Customers who prioritize cost‑effectiveness over pristine condition and are willing to accept minor defects in exchange for significant savings.

Please purchase cautiously. All clearance items are sold as‑is, with no returns or exchanges unless the product is completely non‑functional upon arrival. We do not offer full refunds for cosmetic or accessory issues.

Shipped 4 complete batteries

Shipped 4 complete batteries . 2 very good condition and 1 was quite used. The weakest battery measures about 75...80Ah. Rest measure around 100Ah. For the money paid this is a good deal.
