• 🍃【Massive 16kWh Energy — Double Power, Double Runtime】The WattCycle 24V 314Ah LiFePO₄ Battery 2-Pack delivers a combined 16,076Wh of real usable energy, offering a dramatic upgrade for RV full-power setups, whole-home solar storage, marine systems, and continuous off-grid living. Built with EV-grade A+ cells, each unit provides 15,000+ cycles, ensuring over a decade of reliable performance with far greater efficiency than lead-acid or multiple small-capacity lithium packs.
• 🍃【600A Continuous Output for Heavy-Duty Loads】With two batteries working together, the system supports up to 600A continuous discharge, 700A peak, and 1200A burst power—making it capable of running large inverters, AC units, induction cooktops, heavy trolling motors, and high-demand off-grid equipment with minimal voltage drop. Ideal for RV boondocking, marine propulsion, mobile workshops, and commercial-grade power systems.
• 🍃【Dual Bluetooth 5.0 Monitoring & Full-System Protection】Each battery includes a 300A Smart BMS with independent Bluetooth 5.0 monitoring. View real-time SOC, voltage, current, temperature, cycle life, and fault logs for each unit via the WattCycle App. Features automatic low-temperature cutoff (–4°F), over-voltage & under-voltage protection, short-circuit protection, and advanced thermal management—ensuring your dual-battery system stays safe in all environments.
• 🍃【Compact, Rugged & Easy to Install in Pairs】The 2-Pack features two compact 18.9 × 14.25 × 9.53 in batteries, each with a reinforced aluminum frame for zero-swelling reliability and an IP65 waterproof steel shell for harsh outdoor use. At 45% lighter than equivalent lead-acid banks, installation is easier, while the top-terminal layout simplifies wiring for RVs, boats, cabins, and off-grid power walls.
• 🍃【Expandable System for Large-Scale Energy Storage】This 2-Pack supports scalable system design, allowing expansion up to 64.3 kWh for whole-home backup, RV power walls, and large off-grid energy banks. Also supports 48V setups using 2 units in series when needed. Perfect for solar storage, marine systems, UPS backup, and mobile or stationary power applications requiring high-capacity, long-life energy.
