I tested Graphene packs about 8 years ago when HW released and graphene was a hype. More early than late I realised that his life is very short and don't meet expectations.
Should add a column on the spreadsheet whether you can buy each brand in the US, EU etc cause CNHL does not sell to the EU via amazon but does have a warehouse in the EU if you buy on their website. Importing to the EU is a pain in the ass and not practical, especially batteries.
I wouldn't know how to do that and know the challenges some face in certain countries. For example, would you have known I paid an extra 100 canadian to bring some of these packs across the canadian border? They are still accessible by Canadians but it will cost.
I've had a few 4000 mah 6s turnigy graphene panther lipos and found them to be powerful but heavy and swelled quite quickly when bashing. it was a few years ago though. I just use the turnigy heavy duty 4000 mah ones now there good enough for me for the price
@user-oh5in7rv7l this makes more sense. However, if I were to do this on my charger I'd get around 25 milliohms total on the 4s pack and the result doesnt fully agree with my own voltage drop measurements while loaded in an RC. I can't explain this discrepancy yet.
They changed the cells but word on the street is that these are the same. At one time the Panthers had the better cells. People say that's not the case anymore
Thanks for the test! It helps a lot in my decision for CNHL. A comparision to HRB would be interesting too.

Is it possible to just wire a switch inline with the dial. Could also still use in either mode by alternating starting positions?

Hi Ryan. Went flying this last Sunday. Did you get a chance to fly on one of these "strange" weather days ?
Hey Frank. That sounds awesome! It didn't even cross my mind to come out and fly. It's just not usually a thing in February.

They are saying the cells themselves are 2 miliohms each. 15-11 = 4 with 2 extra cells, so the rated spec isn't far off the 1.86 you measured.
You mean that the first 4 cells are 2.75 milliohm and the last 2 are 2.0 milliohm? Isn't that a significant QC issue?

at witch temperatur you measure the resistance?
22 to 23C
I only expect 20c out of any pack no matter what the label says and I'm never disappointed

So what you're saying is that people aren't getting what they think they're paying for?
That's one way to look at it
Lol cheap batteries for the win?
HRB FTW
Interesting choice!
