The BP3800 is a 3.84 kWh add-on battery for the Anker SOLIX F3800 and F3800 Plus portable power stations. One unit doubles the host station to 7.68 kWh, and up to six can be stacked for roughly 26.9 kWh, enough for multi-day home backup or RV and EV charging. It is not a standalone battery: it only charges, discharges and reports through the host station and the Anker app. Owners like the plug-and-play setup and fast switchover with the Home Power Panel, but the daisy-chain cabling between multiple units is bulky and awkward to route.

Owners describe the BP3800 as an easy, reliable way to extend an F3800, with simple plug-and-play hookup and quick backup takeover through the Home Power Panel. The main complaints are about the wiring between multiple batteries, which looks jumbled and is fiddly to connect.
