Looking for 272ah or 280ah cells

Hi

I think I need your help.

The battery turned up, and I performed a capacity test, and it came out at about 81ah compared to the advertised 300ah. Quite a difference.

However, as I'm sure some of you will have anticipated the seller is not accepting this, and AliExpress have not accepted my evidence that the battery is not as advertised.

I posted this photo of the discharge test, just before it ended, and initially the seller argued that the battery can go down to 10v, so my test wasn't correct,



and now AliExpress are saying that the meter I used (which they sell) isn't valid to do such a test. I think I'm screwed here. Any thoughts?

This deserves its own thread, and will be a bit of a drawn out process to help you.
