WattCycle 12V 314Ah Mini LiFePO4 Lithium Battery with Bluetooth 5.0, 200A BMS, 4.01kWh Energy, IP65 Waterproof, 15000 Cycles, for RV, Marine, Solar Off-Grid

• 【Hassle-Free High Capacity】This WattCycle 12V 314Ah Mini LiFePO4 Lithium battery delivers 4.01 kWh of energy—surpassing three 12V100Ah or 12V 300Ah lithium batteries in parallel. It easily powers RV appliances (fridges, ACs) for 3 consecutive days during boondocking and supports up to 4S4P configurations to build a 64.307 kWh system, perfect for solar off-grid setups, home backup, and marine use. Meets IEC/ROHS/CE standards for reliable performance
• 【Advanced Conductivity System】Built with high-grade braided oxygen-free copper wires, this battery boosts current output efficiency by 50% and handles devices over 2000W (like 2000W pure sine inverters). The low-resistance design ensures stable power for heavy-duty needs—from trolling motors to RV air conditioners—making it a true upgraded version of standard 12V 300Ah LiFePO4 batteries
• 【Superior Protection Technology】Its built-in 200A BMS offers 15+ protections (over-charge, short-circuit, over-current), while premium aluminum cooling fins speed up heat dissipation by 30% to prevent overheating. It also has a smart low-temperature cut-off (-4°F/-20°C) that stops discharging in freezing conditions, auto-recovering when temps rise above 41°F—ideal for winter camping or cold-climate solar use
• 【Full-Aluminum Skeleton Design】The unique full-aluminum internal frame eliminates swelling risk, even in high-heat environments, and creates a shock-resistant structure that passed UL62133 safety tests. The durable ABS+PC (UL94 V-0) case adds extra protection, making it tough enough for bumpy RV trips or marine vibrations
• 【Smart Bluetooth 5.0 Monitoring】Via Bluetooth 5.0 (300ft range), the WattCycle App lets you check voltage, temperature, and depth of discharge (DOD) in real-time—no need to crawl under RV floors or climb to solar arrays. It’s compatible with other WattCycle 12V systems, including golf carts and camper backup power, for unified monitoring
• 【Lightweight & Powerful Lead-Acid Replacement】Made with EV Grade-A cells, it lasts 10+ years with 15,000 deep cycles (vs 300-500 cycles for lead-acid). At 59.52lbs, it’s 1/3 the weight of a 12V 300Ah lead-acid battery, charges 2x faster, and requires no complicated wiring—cutting installation time for DIY solar setups
• 【Mini Size for Versatile Fit】With dimensions 9.76"H x 15.12"W x 7.64"L, it fits tight spaces in RVs, boat compartments, or home storage closets. Compared to lead-acid, AGM, or SLA batteries, it saves over 50% space and weight, making it the top choice for efficient solar energy storage and weekend camping trips
