We use both non-relativistic QCD (NRQCD) and fully relativistic formalisms to calculate semileptonic form factors for the decays B_c → eta_c lv and B_c → J/psi lv over the entire q2 range.To achieve this we employ a highly improved lattice quark action and at several lattice spacings down to a=.044 fm, which allow a fully relativistic treatment of charm and simulation of the full q2 range with controlled continuum extrapolation. We have two ways of treating the b quark: either with an O(alpha_s) improved NRQCD formalism or by extrapolating a heavy mass m_h to m_b in the relativistic formalism. We find good agreement between these approaches which provides an important cross-check of our results
