Temp rise from current flow

[Minerva]

Would a pair of 4500 Ampere Hour 48VDC wet cell battery banks provide enough current to heat a piece of metal this thickness to plastic state rapidy to facilitate bending without changing proper temper too much?

There is no load bank in town that goes that high but the Deka banks just got 2000MCM cables installed on them. Everyone is too chicken to try a shunt test! :evil:

I think you would risk exploding the battery, no?

The plates are thick and designed to put out well over 20C rates for perhaps a minute or even more. That's a lot of power and the enclosures are properly vented to remove hydrogen emissions too.

i'm pretty sure that once you heat a sway bar up to the poin that it can be easily bent its already destroyed, i think the anealing process is what allows it to flex without cracking.

This is why two are going to be attempted and the other source of heating would use an RF source but that's really complicated. 🙂

90kA - damn, what are the physical specs of these babies

Too heavy for the big joes to move them lol. The whole ass came off the ground trying to fork those!
