Ya, the OP is not telling the truth. One there isn't a "variety", second they aren't UL listed at that price. I've spent months researching this space for an off grid setup and these are the two best setups direct from China from a cost standpoint for 15 kWh. Neither are UL listed: https://www.apexiummall.com/index.php?route=product/product&path=230_240&product_id=526 https://www.apexiummall.com/index.php?route=product/product&... https://yixiangpower.com/products/yixiang-vertical-15kw-diy-lithium-battery-box-kitus-stock-16pcs-eve-314ah-brand-new-grade-a-lifepo4-battery-cellchina-stock?sca_ref=9207522.jYuzmwEjUpH https://yixiangpower.com/products/yixiang-vertical-15kw-diy-... Both would cost roughly $4800~$5500 for that total size. If you want good customer service, dependable, UL listed, and correctly priced, then this is the king: https://signaturesolar.com/eg4-wallmount-indoor-battery-48v-280ah-14-3kwh-indoor-heated-ul1973-ul9540a-10-year-warranty https://signaturesolar.com/eg4-wallmount-indoor-battery-48v-... UL listed ~45 kWh will cost you $10k, not $5.4k.
