Two Anker SOLIX rows already sit next to each other on the Off-Grid Power Pro station table, and they do not agree about expandability. C1000 is Expandable: Yes. C1000 Gen 2 is Expandable: No. The official US product page for the Anker SOLIX BP1000 Expansion Battery is the manufacturer source for that split.
This page matches one add-on battery to those catalog rows. Specs below were read from Anker’s US listing on August 21, 2026. That manufacturer page is the spec source, not an Anker affiliate program. This site did not test the pack, did not time a runtime, and does not invent a price. Anker SOLIX is not on our Awin account. EcoFlow mentions below are not affiliate links.
What Anker prints for the BP1000
The US title is Anker SOLIX BP1000 Expansion Battery – 1,056Wh LFP (For Anker SOLIX C1000). On that same page Anker prints:
- 1,056 Wh capacity (also written 1056Wh)
- 19.97 lb / 9.06 kg
- 3,000 cycles to 80%+ capacity on the spec table; the marketing bullets also print 3000 life cycles and a 10-year lifespan
Treat those as manufacturer claims as of the source date. Remaining capacity after 3,000 cycles is the 80%+ threshold Anker printed.
Two fields are missing on purpose. The official US page does not name a connector or print a port voltage, so none appears here. The page is also not used as a price source.
Compatible — and not compatible
Keep the pairing lines separate. They are not identical.
The headline says the pack works seamlessly with SOLIX C1000. The tech-specs Compatibility line says it works with Anker SOLIX C1000 and C1000X. A note on the same page says it is not compatible with Anker SOLIX C1000 Gen 2.
FAQ Q7 on that page is stricter than the spec table. It says the BP1000 is only compatible with the C1000 and cannot be used with other power stations. That FAQ answer does not name C1000X; the spec table does. Both sentences are on the same official US page.
The same FAQ answer prints the reverse rule for the station: the C1000 can only be expanded using the BP1000 and is not compatible with other batteries like BP3800, BP2000, or BP2600.
As of August 21, 2026, that is the pairing Anker printed:
| Station or pack | What the official US BP1000 page prints |
|---|---|
| Anker SOLIX C1000 | Compatible (headline, specs, and FAQ) |
| Anker SOLIX C1000X | Listed on the spec table only; FAQ Q7 does not name it |
| Anker SOLIX C1000 Gen 2 | Not compatible |
| BP3800, BP2000, or BP2600 on a C1000 | C1000 is not compatible with those packs, per FAQ Q7 |
C1000X is a manufacturer pairing on that spec table. This article does not claim C1000X as a row on the live Pro table.
The live table already shows the split
Check the mid-size station table on Compare. Anker SOLIX C1000 is Expandable: Yes. Anker SOLIX C1000 Gen 2 is Expandable: No.
If the station you have is a C1000, the expansion battery Anker names is the BP1000. If the station is a C1000 Gen 2, the same official page says the BP1000 does not work with it. Close model names are not a substitute for the printed compatibility line.
How this site reads manufacturer pages — and what it refuses to invent — is on How we compare.
Other catalog-matching packs
Monday research also logged official US expansion batteries for other expandable rows on that table, including a Jackery pack for Explorer 1000 Plus and an EcoFlow extra battery for DELTA 3 / DELTA 3 Plus. Those are other catalog-matching packs, not this article’s subject. Their specs are not repeated here. EcoFlow Awin is still pending, so those mentions are not affiliate links.
What this page will not add
No street price. No invented connector voltage. No max pack count and no expanded-system watt-hour total — those figures are not on the BP1000 US page. No C1000 or C1000 Gen 2 runtime, output, or charge-time numbers. No ranking. No Anker Awin link (Anker SOLIX is not on our Awin account). No EcoFlow affiliate link.
If Anker changes the pairing later, re-check the official US BP1000 page and the live compare table.
FAQ
Does the BP1000 work with Anker SOLIX C1000?
Yes, as printed. The official US headline, tech specs, and FAQ Q7 all name C1000.
Does it work with C1000 Gen 2?
No. The official US page says it is not compatible with Anker SOLIX C1000 Gen 2. The compare table marks that row Expandable: No.
Does it work with C1000X?
The tech-specs Compatibility line lists Anker SOLIX C1000 and C1000X. FAQ Q7 on the same page says the BP1000 is only compatible with the C1000 and does not name C1000X. This article does not collapse those two lines.
Can a C1000 use a BP3800, BP2000, or BP2600?
Not according to FAQ Q7. That answer says the C1000 can only be expanded using the BP1000 and is not compatible with those other packs.
What capacity, weight, and cycle life does Anker print?
1,056 Wh. 19.97 lb / 9.06 kg. The spec table prints 3,000 cycles to 80%+ capacity; bullets also print 3000 life cycles and a 10-year lifespan. Manufacturer claims, not independent tests.
