Most drill/driver battery packs do not have terminals one can clip
onto,they have flat contacts recessed to prevent accidental shorting.
One would have to build a socket for the pack to plug into,with contacts to
mate with the pack's contacts. Or cannabalize an old,spare charger for the
socket/contacts.
