12V 8Ah Off-grid Solar Lithium-ion Battery

【Value for Money】Vastsea off-grid solar lithium iron phosphate batteries feature an impressive 4000~7000 cycle life and a service lifespan of up to 10 years. Compared to conventional AGM/SLA batteries, our products deliver higher energy density, more consistent performance, and greater power output, making them ideal for diverse applications.

【Ultra-Lightweight Design】At just 72 lb per module, our 12V 300Ah battery weighs only one-third of a comparable AGM/SLA battery. Free from heavy and rare metals, it is also completely pollution-free.

【Superior Safety Performance】All Vastsea batteries support series or parallel connection configurations, with no risk of overheating, combustion, or explosion even under high temperatures or overcharging conditions. The built-in Battery Management System (BMS) provides comprehensive protection for the battery’s internal structure.
