  We have used new measurements of the B/C ratio in galactic cosmic rays at
both low and high energies by the Voyager and AMS-2 spacecraft, respectively,
along with propagation calculations using a truncated LBM to examine the
implications of these new measurements over an extended energy range from a few
MeV/nuc to 1 TeV/nuc. We find that the predictions from both the truncated LBM
and the Diffusive Reacceleration model for GALPROP both agree with the Voyager
and AMS-2 measurements of the B/C ratio to within +/- 10 percent throughout the
entire energy range from 50 MeV/nuc to 1 TeV/nuc. The two propagation
approaches also agree with each other to within +/-10 percent or less
throughout this energy range. In effect a diffusion model, without significant
additional acceleration, provides a match within +/-10 percent to the combined
data from Voyager 1 and AMS-2 on the B/C ratio from 50 MeV/nuc to 1 TeV/nuc.
The B/C ratio below 50 MeV/nuc measured at V1 exceeds the predictions of both
propagation models by as much as 3 sigma in the data measurement errors.
