Our take on the Anker SOLIX BP3800 Battery

The Anker SOLIX BP3800 is an expansion battery for the Anker SOLIX F3800 portable power station. It stacks onto the F3800 to raise total stored energy, so the pair runs a home backup setup or long off-grid sessions far longer than the F3800 alone. It uses the same LiFePO4 chemistry as the F3800, which is known for long cycle life and stable output. It only makes sense if you already own or plan to buy an F3800; on its own it powers nothing.

Best forF3800 owners who want longer runtimeHome backup for outagesOff-grid and cabin powerLong jobsite or event days

Pros

Adds substantial capacity to an F3800 system
LiFePO4 cells with long cycle life
Stacks and connects to the F3800 without a separate charger
Scales with extra units for larger banks

Cons

Useless without an F3800 power station
Heavy and bulky to move

Questions and answers

Does the BP3800 work on its own?

No. It is an expansion battery for the Anker SOLIX F3800 and has no AC outlets or inverter of its own. It needs the F3800 to deliver power.

How does it connect to the F3800?

It stacks under or beside the F3800 and links through the station's battery connection. The F3800 then reports and uses the combined capacity.

Can I add more than one?

Yes. Multiple BP3800 units can be chained to the F3800 to build a larger bank. Each one adds the same capacity.

What battery chemistry does it use?

It uses LiFePO4 (lithium iron phosphate) cells, the same chemistry as the F3800. That chemistry is valued for long cycle life and thermal stability.

Will it work with other Anker power stations?

It is built for the F3800 DIY power system. Do not assume compatibility with other Anker SOLIX models; check the station's supported expansion batteries first.
