If 7 is the spikes above max voltage, then it's officially safe to drive around at 193v. hahahaha. Just kidding.

Ok, so I got off my butt and did it too and got something similar. Pack started off at 154V according to the test meter while my voltmeter in the car showed 152. In 3rd gear from a stop, it's easy to hit 500A with little voltage sag. The most I got from the test meter was 161V while the pack sagged to 148V on my car meter. So, I guess to be conservative, we could say that's 13V above pack voltage when considering voltage sag. A pack of lithiums won't sag as much (supposedly).
