Once when we were on the DYNO this happened and it was found the main DUMP cable was disconnected because we were making some battery changes.
Let us know what you find.

Can you elaborate on this? The failure mode sounds the same as mine.
I tightened all the nuts and connections to the battery which were all very loose. Seemed seemed to help but only slightly.
Can you check my understanding of the ESC controller?
The ESC is connected to the starter battery terminals with 2 connectors. These connections, I assume, draw energy from the starter battery and feed it into to the 2 Dump batteries (when ESC is not active). This feeding to dump battery is done through the thick gauge wires with heavy duty connections which also draw energy from the dump pack batteries to feed to the blower.
The voltmeter reads the voltage on the 12V dump batteries, which wired in series result in 28.3V when charged. Wouldn't the ESC fail to read the 28.X voltage and not function at all if it wasn't using the 2 dump batteries? The failure I am experience seems like the dump batteries are only being charged to a certain point and stopping which is resulting in only a few seconds of WOT before voltage dropping too. Was this what you experienced on the dyno?
Do you think an aux charger would help? How do I order one?
The metal connections on the thick gauge wire seem offset and pretty worn, could this be an issue? Picture attached.
I will try slow charging the batteries to bring them back to 100% and see if that helps. Maybe they have been low too long and the controller isn't charging them past a point.
Thanks in advance.
