The internals of the battery have very little inductance, but any
conductor has something like a nanohenry per foot, and if this
conductor surrounds an area, there is a bit more. For normal signals,
this would be nothing to think about, but with 100 amp pulses, even
that low value can have significant consequences and be worth checking
