Voltage sag in relation to watts

[zeropointbug]

Yeah, well I would say those batteries have simply lost performance then from sitting and not doing much... lipo's have a bad time with sitting around and internally corroding. The power draw from the truck is also limited by how much traction it has.

Hmm.. crap. They probably don't perform better after a few cycles, do they? I can just throw them in the bin

They will always gain a bit of performance after a few cycles of non-use, but when they are that far gone, it will never be enough. I just retired some Hyperion G3's I had since spring 2009, only because they had not been used in a long time. They never really lost much performance, they still have a pack iR of 5-6 mohm vs. 4 mohm when new... they lost capacity mostly, and they lost it unevenly is the main thing (2 3s packs in series for 6s), so I can't use them together; other than that, they have plento power.

I have no experience with the HV esc's, but my best guess would be some sort of soft cut-off like you said, it must cut the power a bit to let you know... instead of the typical temporary power shutdown of most cut-off's. ?

Jup, that's soft cut off. It won't give you full power but only 50% or so.


Thanks for all the help ZPB :)

No prob.

Venlo, that's in the far east right? My relatives live around Oudewadering, Leiden, Leiderdorp, and others.

South-east indeed. It's only about 2 hours driving from Leiden. Holland is such a small country
