Generally a thumbs up!
The batteries appear to be working well. The flexibility of the AC300/B300 units would be improved by having battery input ports on both sides and the ability to plug a wind power system directly into the AC unit.

Great portable power setup that is quiet and fumes free. Makes for a much better environment to operate our field testing equipment by removing the generator. Bluetti customer service were very responsive and helpful in recommending a setup and the required cables to operate the B300 with AC200P
