Auto Self‑Heating Tech: When the temperature is below 32°F (0°C) during charging, the self-heating system activates using power supplied by a charger with a current output greater than 7A. Once the battery warms to 37°F (3°C) , charging automatically begins. This helps prevent damage caused by low-temperature charging and ensures dependable performance even in cold environments.High-Density Powerhouse (12.8V 320Ah): Massive energy in a compact footprint. Delivers 4096Wh of capacity while measuring just 13.58×7.48×9.64 inches. At 55.55 lbs, it provides 3x the energy of traditional lead-acid batteries at 1/3 the weight.Robust 200A BMS & High Discharge: Built for heavy loads. Features a powerful 200A BMS that supports 200A continuous discharge and a massive 650A surge (＜3s), making it ideal for running air conditioners, microwaves, and large inverters.Smart Bluetooth 5.0 Monitoring: Stay in control with the KeepKnow App. Track voltage, current, remaining capacity, and battery health in real time right from your smartphone, with no external battery monitor required.Rugged IP65 & All-Weather Design: Engineered for harsh environments. Encased in a flame-retardant, military-grade ABS shell with IP65 water/dust resistance. Operates reliably from -4°F to 140°F with built-in low-temp charging protection.Massive System Scalability: Flexible expansion for off-grid living. Supports up to 4S4P configuration (4 Series, 4 Parallel) to build a colossal 48V (51.2V) 1280Ah system with 65.5kWh of energy storage.EV Grade-A Longevity: Powered by premium LiFePO4 cells delivering 4,000+ cycles at 100% DOD (6,000+ at 80% DOD). Designed for a 10+ year service life, offering true maintenance-free performance.Versatile Charging Compatibility: Recharge efficiently via LiFePO4 Chargers (14.6V 20A+ recommended), Solar Panels (MPPT), or Alternators. Fully compliant with FCC, CE, RoHS, and UN38.3 standards.Exceptional KeepKnow Service: Experience worry-free power with our 5-Year Warranty, lifetime technical support, fast delivery, and responsive 24/7 customer service.
