Radion pros g3

After 2 years of speculation, i recently purchased 3 radion xr30w pros gen 3 from brs. They didn't come with the big battery packs (ballasts) i see everyone has, but came with 3 small adapters, like the ones on the xr15w. Is that normal?? Did they recently upgrade their products or was it a mistake? Yes all 3 lights came with adapters.
