Humsienk Opens Prime Day 2026 on June 12, Permanently Retiring Its 12V 150Ah Group 31 LiFePO4 Battery

Humsienk launches Prime Day 2026, the brand’s largest sale event to date, running 19 days from June 12 to June 30 with discounts up to 60% across its LiFePO4 lineup for fishing, RV, golf cart, home, and off-grid applications. The event also permanently retires the 12V 150Ah Group 31 LiFePO4 battery as stock dries up, marking the end of an era for that core product. Customers can earn double loyalty points, receive a Lucky Spin Wheel entry, and access a 7% discount with PrimeDay7% on top of sale prices. A 5-year warranty, 30-day price protection, and price-match guarantee underpin purchases, while pre-orders for the upcoming inverter series open during Prime Day for July 2026.
