Sorry for the (slight) change in subject. But are the 40160 (20Ah or 16Ah) cells available?

Thanks!

I talked to someone direct at headway on Monday. Currently the 12Ah and 16Ah are not in production. There was a small sample run. They plan on being in full production with in 1-2 months.....earlier if possible.

Just a warn:

I Tested the 10 Ah and 12 Ah cells. The 12 Ah cells have lower C capabilities than the 10 Ah. The voltage of the 12 Ah cells drops below 2V at 9C.

how'd you test that 9C discharge Crodriver? Got a graph?

I have tested it with a simple load and a cycle analyst. Today a friend of mine tested it with professional equipment and confirmed my results.

I have recorded the data from my test, I'll have to find it. Here is a graph of my friend:

He also told me that he felt some vibration in the cell when discharged at high currents (?!).

We know that it has some kind of valve for high pressure protection inside. Maybe the vibration is related to the valve.

good info, but realize, the 12 and 16Ah cells are not in full consumer production.... it was a test run. There were some issues with the 16Ah cells too.

I remember when there were issues with the 10Ah cells and it seems like they've gotten much better.

Thank you, frodus. Hopefully the 16Ah cells (are these 40160S cells?) will come out in time for your next boat shipment of other cells!

Yes, we can't wait to get confirmation on the new cells performance from someone incorporating them into something bigger then an e-bike...hint hint

I'll settle for getting the word from someone who put them in an ebike.

In fact, I'll volunteer to be the one!
