So, if you have a shortly pack, it must be installed in a chassis that will fit a standard full-size pack. Foam spacers can be installed to position the battery, but no electronics or other components can be installed in the battery area. Basically, when the short pack is removed, a full-size pack must fit in its place without having to change anything on the car. Also, two shortly packs cannot be used in saddle configuration. 1S saddle packs can be hooked up in series to produce a 2S1P, 7.4V battery. But, a pair of 2S packs connected in parallel is not legal.
