Only GRECELL 4000W Power Station S5 is compatible with the expansion battery. To connect S5 solar generator with the expansion battery by the included battery packs connecting cable. Can I use S5-BAT Expansion Battery separately? The expansion battery cannot be used separately. It must be connected to the GRECELL S5 power station 5040Wh to charge or discharge. How long will S5+S5-BAT bundle power my device? Working time (estimated) = 10080Wh * 0.85 / operating power of your device. (0.85 = Conversion Rate) Kindly note the actual working time may vary under different circumstances. When charging a device, will the power in the external battery be used first? Both the expansion battery and GRECELL power station will gradually equalize their power levels. When outputting power, a balanced discharge is achieved based on both devices' power levels. This setup is designed to maximize product lifespan. What should I do if I bought a bundle, but only received one product? You may receive multiple packages from different carriers.

Highlights: 10.08kWh Expandable Capacity for Whole-Home Backup：Base capacity 5.04kWh, expandable to 10.08kWh by adding the included smart extra battery.
