Yes, absolutely. All models—including the F1PRO, F1PRO+, and F2/F4/F6/F8/F15/P60-160 series—are built withpremium A-grade LiFePO₄ (lithium iron phosphate) short-blade cells, known for exceptional thermal stability and safety. They are engineered to operate reliably in temperatures ranging from-20°C to 55°C, making them resistant to freezing cold, desert heat, and high-altitude environments. With12 layers of intelligent protectionand a built-in BSM (Battery System Management) module, these products ensure safe, stable, and durable performance over thousands of cycles.

For safety and system integrity,all models in this lineup do not support series or parallel connections. Each unit already features optimized internal cell balancing, advanced BMS (Battery Management System), and precise voltage regulation. Allowing external linking could lead to imbalance, overheating, or damage due to mismatched charge levels or communication errors. Instead, each model is designed as a standalone, plug-and-play solution with clearly defined voltage and power outputs (e.g., 12V, 24V, 48V, 60V), so you can confidently choose the right one for your specific application without complex configurations.

TheF1PRO and F1PRO+ share identical performance specs, including 10,000mAh capacity, 18W fast charging, 150PSI air compressor, 16-LED shadow-free flashlight, and 12V universal vehicle support. The key difference isweight: the F1PRO+ weighs823.4g, while the F1PRO weighs896.2g—making the "+" versionover 70g lighterand more portable. If you prioritize ease of carrying (for travel, emergency kits, or daily use), go with theF1PRO+. For all other purposes, both deliver the same powerful, reliable performance.

Yes. TheF6 (6kWh module)has a massive487.5Ah capacity at 12V, allowing it to safely deliver up to2400W of continuous load powerthanks to its high-current MOSFET design and advanced thermal management. While 12V systems typically require thicker cables due to higher current (I = P/V → 2400W / 12V = 200A), the F6 is specifically engineered to handleup to 200A max discharge current, ensuring stable output even under heavy loads. It’s ideal for marine, audio, and off-grid applications where high-amperage 12V power is essential.

All F-series and P60-160 modules come equipped withreal-time Bluetooth app monitoring, allowing you to view state-of-charge (SOC), voltage, current, temperature, and historical data directly from your smartphone. Unlike basic LED indicators, this system uses precision sensors and algorithmic calibration for±1% SOC accuracy, giving you full visibility and control. The F1PRO and F1PRO+ also feature adigital displayshowing exact voltage and charging status—ensuring no guesswork when it matters most.
