Nah I'll wait and see once the kits are out - but judging by the pics on the Schumacher site, the main belt runs over the top of the pack (or the 4 cells on the NiMh version), so I doubt there is enough clearance for an extra 7mm or so.
Plus it also looks like the battery strap pivots at the front, which again means there is no way of adjustment if it's been designed around a standard height pack.
Hey ho - not a problem
