WattCycle 12V 314Ah LiFePO4 Lithium Battery, 4.02kWh 12 Volt Lithium RV Batteries with Bluetooth, Built-in 300A BMS & EV-Grade A Cells, 15000+ Deep Cycles Battery for RV, Marine, Solar, Off-Grid

Features

• 4.02kWh High-Density Energy Output Engineered for demanding applications, the WattCycle 12V 314Ah lithium battery supplies over 4kWh of usable energy in a compact, space-efficient design. Weighing just 61.72 lbs, it replaces bulky lead-acid banks while fitting seamlessly into RVs, boats, off-grid cabins, UPS systems, and emergency home backup installations.
• EV-Grade LiFePO Cells for Extended Service Life Manufactured with EV-grade A LiFePO cells, delivering up to 6,000 cycles at 80% depth of discharge and over 10 years of operational life. It is optimized for solar energy storage, RV living systems, marine electronics, and off-grid power setups requiring long-term durability.
• Full Smart BMS for High-Load Safety The integrated 300A Battery Management System supports high-current discharge up to 3840W, with controlled peak output for surge loads. It actively protects against over-current, over-voltage, over-discharge, short circuits, overheating, and imbalance, ensuring safe operation for inverters and power-hungry devices.
• Reinforced Metal Structure & Cold Protection A full aluminum internal frame enhances vibration resistance, structural rigidity, and heat dissipationimproving cooling efficiency by up to 30% during heavy operation. The IP65-rated housing resists dust and water exposure, while low-temperature cutoff halts discharge at 4F to protect the battery in cold climates.
• Bluetooth Monitoring & Scalable System Design Built-in Bluetooth enables real-time tracking of SOC, voltage, current, and temperature through the WattCycle app. Compatible with LiFePO chargers, solar controllers, and generators, supporting 1C charging. Expandable up to 4S4P for energy systems reaching 64.3kWh. Certified UN38.3, CE, FCC, and RoHS.
