Sounds like you may want to take pac apart and see if connections are sound. That'd be the 1st thing I'd look at given the behavoir.
Thanks! The pack had a lot of air under the shrinkwrap. The cells were not puffed by the altitude in CO made the air under the shrink wrap "casing" was enough that it must have been placing enough pressure to cause the issue. A small slit in the underside and all is well. Ran great today after 2 charges. I will be keeping my eye on it but behaves fine so far! Weird.
