I. Product Overview This product is a 12.8V 314Ah lithium iron phosphate (LiFePO₄) deep-cycle battery with a total storage capacity of 4.0kWh (approximately 4019Wh). It uses Grade A square aluminum-cased lithium iron phosphate cells and features a built-in intelligent BMS battery management system. It can directly replace a 12V lead-acid battery pack (typically requiring 4-6 100Ah lead-acid batteries in parallel) without modifying the existing system. Applicable fields: Large-scale off-grid solar energy storage, main power for RVs/campers, marine/yacht power and domestic electricity, home UPS backup power, communication base station backup power, golf carts, low-speed electric vehicles, and industrial equipment. II. Core Features 1. Ultra-large capacity, one-stop energy storage A single 314Ah battery (approximately 4 kWh) can meet the basic daily electricity needs of an average household (lighting, refrigerator, television, fan, etc.). Large capacity requirements can be achieved without multiple batteries in parallel, reducing installation and wiring workload and potential points of failure. 2. Over 6000 cycle life: Lead-acid batteries only have a cycle life of 300-500 cycles, while this product supports over 6000 deep charge-discharge cycles (80% depth of discharge). Based on one complete charge-discharge cycle per day, the lifespan can reach 10-15 years, significantly reducing long-term electricity costs for users in remote South America. 3. High power discharge: Maximum continuous discharge current of 150-200A, peak discharge current of 300-400A (≤5 seconds), capable of driving 3000W-4000W inverters, meeting the simultaneous operation needs of high-power appliances (air conditioners, induction cookers, water pumps, power tools). 4. Built-in intelligent BMS: Safe and reliable. The BMS provides overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, temperature protection, and cell balancing functions. Even under prolonged high-load operation in the hot climate of South America, it remains safe and stable. 5. Lightweight design, significantly reducing weight: A single battery weighs approximately 28-32kg, while a lead-acid battery pack of the same capacity (approximately 300Ah) typically weighs 80-100kg. Lightweight design reduces the load on RVs and boats, lowering transportation and installation costs. 6. Flexible expansion capabilities: Supports up to 16 identical batteries in parallel (total capacity exceeding 5000Ah/64KWh), and up to 4 batteries in series to form a 48V system. Capacity can be flexibly expanded to meet the power needs of South American customers. 7. IP65/IP67 waterproof (optional): High protection rating ensures long-term stable operation of the battery in outdoor, humid, and rainy environments, making it particularly suitable for South American rainforests, coastal areas, and open-air solar energy storage projects. 8. Low-temperature charging self-heating (optional): Winter temperatures are low in some parts of South America (such as southern Chile and Patagonia, Argentina). An optional self-heating function allows for safe charging at -20℃, ensuring year-round availability. 9. Bluetooth/RS485/CAN Communication (Optional): Supports real-time monitoring of battery voltage, current, remaining power, cell temperature, and other data via a mobile app, facilitating remote management by local installers and end users. 10. International Certifications, Hassle-Free Export: Certified by CE, RoHS, MSDS, and UN38.3, meeting international transportation and import customs clearance requirements of South American countries.
