[gmx-users] charges in vaccum simulations

I have a small query regarding neutralization of charges in vaccum
I would like to simulate in vaccum 10 copies of 10 residue peptide
containing one charged residue lysine (I am interested in monitoring
cation-pi interactions between them).
1) Would you suggest me to neutralize the system (since electrostatic
neutrality is required for the MD simulations of the system) even though I
would like to monitor cation pi interactions?
2) How can I deal with the charges in-vaccum simulations? Since there are no
solvent molecules with dipole, would the addition of salt ions be
energetically be stable?
3)Also, I have read few papers in which MD simulations were carried out
without neutralization of charges. Is it reasonable to carry out such
Thanks in advance.
