- 【Advanced Smart BMS & All-Weather Safety】Equipped with an upgraded 100A Smart BMS, our battery provides comprehensive protection against overcharge, over-discharge, over-current, and short circuits. Unlike standard lithium batteries, it features automatic low-temperature cut-off, preventing charging below 32°F (0°C) to avoid cell damage. Built with stable LiFePO4 chemistry, it eliminates the risk of thermal runaway, ensuring maximum safety for your RV, boat, or home energy system in any season.
- 【Ultra-Lightweight & Perfect Group 31 Fit】Weighing only 24 lbs—70% lighter than comparable lead-acid batteries—this 12V 100Ah battery makes installation and transport effortless. Its compact dimensions (12.9" x 6.7" x 8.5") are a precise drop-in replacement for BCI Group 31 battery boxes. Ideal for upgrading marine trolling motors, RV house banks, or golf carts without modifying existing compartments. Enjoy maintenance-free power with no acid refilling or corrosion worries.
- 【15,000+ Cycles & 10-Year Lifespan】Invest once, save forever. Our premium Grade-A LiFePO4 cells deliver 15,000+ deep cycle life at 60% DOD and over 8,000 cycles at 80% DOD, lasting 10x longer than traditional lead-acid batteries. With a 10-year service life, this battery drastically reduces your long-term cost per cycle. Whether for daily solar storage or weekend camping, it maintains consistent voltage output until fully depleted, unlike lead-acid batteries that dim as they drain.
- 【Fast Charging & Flexible Energy Expansion】Recharge 3x faster than lead-acid options with zero memory effect. Fully charge in just 5 hours using a 14.6V 20A LiFePO4 charger, solar panels, or alternator. Designed for scalability, connect up to 4S4P (4 in series, 4 in parallel) to build massive systems up to 51.2V and 400Ah. Perfect for DIY off-grid solar setups, whole-home backup, or powering high-draw devices like CPAP machines, electric wheelchairs, and outdoor power stations.
- 【Reliable Power for Critical Applications】Engineered for stability in extreme conditions, operating reliably from -4°F to 140°F (-20°C to 60°C) during discharge. Delivers 100% rated capacity even under high loads, making it the trusted choice for saltwater fishing boats, off-road vans, and emergency home UPS. Backed by our dedicated US-based support team, we provide a 24-hour response guarantee for any technical questions or warranty claims, ensuring your power never fails when you need it most.
