Product Details
✓4kWh MONSTER CAPACITY, FEATHERWEIGHT BUILD: Why wire three 100Ah batteries when one does it better? Delivering a massive 4096Wh of energy, this 12V 320Ah powerhouse weighs an incredibly light 58.69 lbs—shedding over 120 lbs compared to triple lead-acid setups. Measuring just 20.49 x 9.34 x 8.69 inches, it completely eliminates the nightmare of messy parallel wiring and saves valuable space in your RV or boat.
✓250A ROBUST BMS & 3200W OUTPUT: Run your entire rig on a single battery! Upgraded with a heavy-duty 250A Battery Management System, this beast effortlessly delivers up to 3200W of continuous output. You can easily run your 15,000 BTU RV air conditioner, microwave, espresso machine, and fridge simultaneously without ever triggering frustrating voltage drops or BMS shut-offs.
✓SMART BLUETOOTH APP MONITORING: Total energy control from your smartphone. Say goodbye to battery anxiety and expensive external shunts. The built-in advanced Bluetooth module syncs seamlessly with the HumsiENK APP, allowing you to monitor real-time capacity (SOC), voltage, current, and cell temperature. Never guess your battery level again, even if it's hidden deep in a battery bay.
✓32°F LOW-TEMP CUT-OFF & ALL-WEATHER SAFE: Invest with absolute confidence. Engineered for extreme outdoor adventures, the smart BMS features a built-in low-temperature cut-off that automatically stops charging below 32°F (0°C) to prevent permanent cell damage during winter camping. Housed in a rugged, vibration-resistant casing, it thrives on harsh overland trails and choppy waters.
✓EV-GRADE CELLS & MASSIVE 4S4P EXPANSION: A true decade-long investment. Utilizing premium Automotive Grade-A LiFePO4 cells, it delivers 6000 to 15000 deep cycles and up to a 10-year service life. Need to build the ultimate power wall? It safely supports expansion up to 4 in series and 4 in parallel (Max 4S4P) to create a staggering 51.2V 1280Ah (65.5kWh) energy storage bank. Backed by a solid 5-year warranty.
