Eagletree graphs may not be accurate

i tested it with the voltage setting
recorder :10v
meter: 20v

then i plugged in an 5s pack and it reads ~40 volts

It's probably less versatile and comes with no warranty but medusa make a 200A 'Oracle'.

That's odd. That would mean that it applies that calibration amount as a multiplier of sorts, and not a static offset. I got different results. I'll have to re-test I guess.

I still want to wait until I hear from ET before I go ordering the new part and modding my current ET just to find out it doesn't work for some reason. I hope the ET engineers will see the email so I can get confirmation that my hunch is accurate (about it not reading accurately above the hall-effect sensor rating). It would be nice to see those actual peak values without trying to extrapolate.

Yeah, I could go with the Medusa solution, but I read they use a shunt, which has insertion losses (and therefore heat). The Hall-effect sensor is a much better solution IMO.
