Dear VASP admin and users,
For NEB calculation is it important to take fine k-mesh or one can do NEB calculation using coarser k-grid. As for diffusion barrier, ultimately we need the difference in energy of the system at initial and saddle point.
with best regards,

as the forces are based on the derivatives of the total energy, a fully converged k-mesh should be used for NEB runs as well.
