The Anker SOLIX BP3800 is a lithium iron phosphate battery module with a single purpose: to sit alongside an F3800 portable power station and grow its reserve. On its own it doesn't work — it charges and discharges only while connected to the power station, which also shows its status in the app.
Each module doubles the energy of the unit it's attached to, and up to six can be connected: from there on, the limit is no longer the battery, but the space you have to put them in.
It sits next to the power station, connected by cable, and has no use of its own: it's extra capacity for anyone who already keeps an F3800 as a home reserve, not a standalone appliance.
