Description
Maximum Power, Minimum Footprint
Reclaim your storage space without sacrificing energy. As an ultra-compact mini 12V lithium battery, it is 32% smaller than a typical 12V 300Ah lithium iron phosphate battery and 54% lighter than three standard 100Ah lead-acid batteries. This high-density 12 volt lithium battery combines exceptional power with effortless portability.
Proprietary 200A BMS for Heavy Loads
Experience stable and safe energy delivery. The proprietary 200A Battery Management System (BMS) delivers 2560W of continuous power and supports up to an 800A peak discharge for 1 second. This ensures your mini lithium battery runs heavy-duty appliances reliably, even under sudden high-power demands.
Rugged Marine-Grade Reliability
Conquer the waters with a robust 12 volt marine battery. Built with an IP65 water and dust resistance rating, along with salt spray and moisture-proof construction, it thrives in harsh environments. It performs flawlessly as a steadfast 12 volt trolling motor battery to keep you moving.
Expandable Energy for Off-Grid Living
Build a resilient home energy or solar setup with an efficient off grid lithium battery. Powered by EV-grade battery cells, it delivers impressive longevity: 4,000 cycles at 100% DOD, 6,000 cycles at 80% DOD, and up to 15,000 cycles at 60% DOD. The expandable design supports 4P4S configurations, allowing you to scale this lithium battery off grid system up to a massive 69.63 kWh of total energy.
Comprehensive Protection & Certified Safety
Equipped with over 20 built-in safety features, including intelligent low-temperature shutdown and automatic overload recovery. Backed by a 5-year warranty and fully certified to UL 1973, FCC, CE, RoHS, and UN38.3 standards, guaranteeing absolute peace of mind.
