Anker SOLIX BP3800 Expansion Battery 3840Wh (LFP) for F3800 Power Station

The Anker SOLIX BP3800 Extension Battery is the essential power expansion solution for owners of the Anker SOLIX F3800 Power Station. Designed to seamlessly integrate with the F3800 and F3800 Plus, the BP3800 adds a substantial 3,840Wh of additional LiFePO4 capacity in a single unit transforming a capable portable power station into a serious long-term energy solution for home backup, off-grid living, RV adventures, and emergency preparedness.

The BP3800 supports connection of multiple expansion batteries, allowing total system capacity to scale all the way up to 26,880Wh. That is enough stored energy to run an entire household's critical appliances for days at a time refrigerators, lighting, CPAP machines, security systems, and more. When fully expanded, the SOLIX F3800 system can scale from 3.8kWh up to 53.8kWh, giving you enough power from one day to two weeks.

Built with a capacity of 3,840Wh, the BP3800 features a robust LFP battery design built to last, with 3,000 life cycles and a 10-year lifespan. LiFePO4 chemistry is not only the most durable and long-lasting battery technology available in consumer power products it is also inherently stable and safe for indoor use. When connected to the F3800, the power of all devices automatically balances across the system, ensuring stable battery health throughout the pack.

Setup is simple and requires no technical knowledge. Just connect using the supplied battery-to-host cable, press the On/Off button for two seconds to power on, and monitor the system status through the Anker app. The unit features industrial-grade wheels and top and bottom carry handles for straightforward repositioning wherever it is needed. Please note the BP3800 cannot be used as a standalone unit — it must be connected to a compatible SOLIX F3800 or F3800 Plus power station to charge, discharge, and function.
